Imagine this scenario: It’s a bright, sunny morning, and Anna decides to take her dog out for a walk like usual. However, she feels herself not enjoying it as much. She goes home and decides to write a poem, listen to music, talk to friends, or play your favorite game–typically things she loves to do–but nothing seems to stick. She chalks it up to ‘fatigue.’ The truth is, this is anhedonia, the inability to feel pleasure or joy from activities that you once enjoyed. About 10% to 15% of adolescents exhibit symptoms of anhedonia [1]. Letting anhedonia go on untreated can be a major concern, as research shows that 58% of adolescents who experience anhedonia go on to be diagnosed with a major depressive disorder later in life [2]. More troubling, among youth undergoing treatment for depression, anhedonia is uniquely tied to treatment resistance [3]. Finding a solution for anhedonia becomes challenging because the majority of people are not aware of it in the technical sense, and anhedonia is often masked under other parameters such as burnout, tiredness, etc. Anhedonia can exist in two forms: physical and social. Physical anhedonia is when physical activities become unenjoyable, such as eating your favorite foods or listening to music, whereas social anhedonia is when one loses interest in talking to friends, spending time with family, etc. Anhedonia is particularly dangerous because it drains an individual of the happiness of daily life, as individuals may find themselves pulling away from social circles, hobbies, and interests. Research shows that anhedonia is primarily caused by an imbalance of dopamine, the hormone that controls reward and motivation. Anhedonia is historically under-researched relative to its massive clinical impact. This is largely due to the fact that psychiatric research typically considered the inability to feel pleasure as a secondary or downstream feature of a low mood, rather than an independent target of study. Moreover, traditional antidepressants (SSRIs) primarily target the chemical serotonin, largely ignoring the dopaminergic reward pathways that govern pleasure and motivation. Ultimately, research also indicates that high stress is associated with anhedonia, as long periods of severe stress can drain your brain's reward system [4]. Although anhedonia may seem untreatable, there are multiple accessible methods to combat it today. Talking therapy can reduce negative thoughts and rebuild habits, while daily exercise, such as brisk walking, jogging, or cycling, can immensely help, as regular elevated heart rates increase brain growth factors like BDNF, helping reset neural circuits linked to reward and motivation [5]. Although current research shows that nearly 32% of teens face extreme stress during the school year, leaving them susceptible to experiencing anhedonia, we should raise more awareness of this topic, understanding that it is not simply fatigue but something deeper.

Learning any new skill, whether it is playing an instrument or learning a language, comes with various challenges. It requires long-term perseverance, and it can feel impossible, especially when improvement isn't immediately visible. Yet, with practice, the skill becomes easier. Why is this the case? The human brain is designed to maintain homeostasis within the body, ensuring that the body is maintained at an optimal level. When our brain is introduced to a challenging new environment, however, the brain begins to adapt. Similar to how, with constant repetition, muscles become stronger, and lungs become more efficient, the brain is also able to modify itself to suit the new environment. This idea serves as the fundamental basis for skill development and neuroplasticity. When learning a new skill, the brain modifies the neuronal connections within the brain. Specifically, the brain produces new neuronal pathways, allowing separated neurons to communicate with one another. But why does it matter? When individuals are expected to perform tasks outside of their respective comfort zones, the brain's neuroplasticity changes the brain's functions, mechanisms, and habits. Eventually, as an individual repeatedly practices the same skill, it becomes easier for the brain to perform. Just remember: it can seem difficult to take on new risks at first, but with practice and a little help from neuroplasticity, you can master skills you once thought were impossible!

Anesthesia is a medical treatment that temporarily blocks pain and other senses during surgery. When it is implemented in surgical procedures, physicians must maintain adequate analgesia. Patients are unconscious and therefore cannot tell whether they feel pain or stress during treatment. Due to the lack of verbal speech or facial expressions, doctors usually use changes in the body, such as heart rate, blood pressure, and other signs of physiological signs, to judge whether enough pain-relieving medicine is sufficiently provided to the patient. However, these signals are not easy to interpret. Medasense’s PMD-200 is a non-invasive monitoring system that is used by doctors to provide a more objective way to measure the body’s response to painful surgical stimulation. This is done by combining several physiological signals with a score called the Nociception Level Index. This measure helps doctors to support decisions about analgesia. Pain and nociception should be thought of as two separate measures. Pain is a subjective experience, while nociception is the nervous system’s response to harmful stimulation. The nervous system reacts to these changes in the body, changing heart rate, blood vessel activity, and sweating. What is extraordinary about the PMD-200 is that it is a non-invasive tool. It uses a finger sensor to collect body signals. These signals are then combined with a score called the NOL, which ranges from 0 to 100. A score of 0 means that there is no nociceptive response, whilst 100 means the response is very strong and high. The PMD-200 helps doctors to make decisions on whether the patient is in need of more or less pain medicine during surgery. The white paper explains that NOL scores above 25 for more than a minute may mean that more analgesia is needed. (Medasense Biometrics, n.d., p.10). This is especially important for young people, as young people should understand that not only front-line doctors are the ones saving lives through medical operations, but technology and medical instruments are also contributing in some capacity. Many people try to follow their dreams of becoming a doctor who saves patients' lives by performing surgery, but an alternative path to this dream of working in the medical field can be to work in biomedical engineering. Therefore, young people who are interested in both medicine and technology should understand that they do not have to choose one path and that they can support patients and improve healthcare without necessarily becoming doctors. The PMD-200 is a non-invasive monitor that assists doctors in providing an approximate measure of nociception during anesthesia. By combining several physiological signals and NOL scores, it can give doctors a better chance of surgical success and decrease medical accidents overall. References Medasense. (2024, February 7).

"The power which a man's imagination has over his body to heal it or make it sick is a force which none of us is born without." Mark Twain What if the most powerful ingredient in a pill wasn't the medicine, but your expectations? In many research projects, scientists employ a pill that affects the body based on what the recipient is told about it. This pill is considered a placebo: something that triggers a genuine response to a non-therapeutic treatment. The placebo effect is an authentic reaction stimulated by a person's belief, expectations, and social cues rather than by chemicals. While scientists cannot fully understand how placebos work, it is known that they involve the brain’s ability to release natural chemicals that mimic the responses typically produced by therapeutic methods. This stems from higher cognitive centers regulating lower sensory and physiological functions. When the body experiences physical pain, the brain typically generates natural morphine-like substances, which act like pain medication. Additionally, neurotransmitter systems like dopamine---which plays a vital role in the brain's reward system---regulate individuals' perception of reality. Yet, there are also other factors, including social and personal conditioning, that contribute to this phenomenon. From mood-enhancing hormones to immense activity in specific brain areas connected to expectation, emotion, and reward, the placebo effect is considered a neurobiological phenomenon. There have been numerous cases where placebos have benefited patients. In a study of Open-Label Placebo Treatment for Cancer-Related Fatigue, it was proven that those who took the placebo during the first three weeks experienced less fatigue than those who only received their normal treatment. In addition, even after the three weeks were over, the placebo group continued to benefit, and the standard treatment group also experienced improvements in fatigue after taking the pill. Researchers use placebos to identify the actual improvements from a drug. Essentially, it acts as the experiment’s control variable. Placebos are integrated widely in trials and acknowledged as the ‘gold standard’ to evaluate whether a treatment is effective. Additionally, it helps scientists test the drug’s true contribution towards the participants or patients; without it, treatment would seem more effective than it actually is. Considering all that the placebo effect can do, there is one question researchers have asked: can negative expectations towards a drug cause the same consequences in patients? The answer is yes---there have been multiple occurrences where people have experienced negative side effects despite having received an inactive substance. This effect is called the ‘placebo effect’s evil twin’ or, more often, the Nocebo effect. Just like the placebo effect, the brain influences the body through expectations. For example, if your doctor says an injection will hurt, the body may perceive it to be painful, whereas the pain may be less intense if the doctor says otherwise. Ultimately, the placebo effect shows us the relationship between the mind and the body and how we can use this knowledge to our advantage. Our mindset is one of the biggest impactors on our health. Just like a pill, the seed of optimism we carry into our lives gives us the power over our body and how we choose to treat it. References Cherry, K. (2011).

“The greatest opportunity offered by AI is not reducing errors or workloads, or even curing cancer: it is the opportunity to restore the precious and time-honored connection and trust between patients and doctors." Dr. Eric Topol, cardiologist and author of Deep Medicine 72% of physicians rely on an assistant that makes their job instantly easier–except this ‘assistant’ wears no face (OpenAI, 2026). From lobotomy to medications and mercury to antibiotics, the practice of medicine continues to evolve through new advancements that tackle important health challenges more effectively. Practices we used to think required cognitive abilities unique to humans can now be sourced from something entirely different through a human creation: Artificial Intelligence. Giant technology companies like Microsoft and Google are now investing in AI research and integration into the healthcare sector. This is no surprise given the vast potential these systems hold in transforming medicine and the delivery of healthcare in ways we have yet to discover. Considering the profound changes that technology has had on healthcare so far, we can imagine AI transforming everyday healthcare for people in the future. In the same industry where physicians used to fall into administrative overload and spend hours in what is called "pajama time," AI now has the power to eliminate this clinical burnout. Before this, doctors had to rush to take notes during patient visits, but with AI, doctors can now give patients their undivided attention and restore connection. Clinicians no longer need to translate everyday conversation into clinical language such as SOAP notes. AI can already automate this task, leaving doctors with more mental energy to make medical decisions. By drastically reducing physician time on Electronic Health Records from hours to minutes, doctors are able to dedicate more time to rest, promoting work-life balance. Still, it is important to recognize that although AI may speed up the documentation process without increasing staff members, only 10% of medical executives have formally integrated it into their workplace (Purohit, 2025). From what used to take days for a team of researchers to interpret, diseases can now be accurately predicted by technology through analyzing immense amounts of data in mere minutes. Every minute, there are quiet clinical eyes watching over hundreds of patients’ vitals, monitoring minor changes in data points to eventually detect irregularities that may be early signs of disease. Multiple companies have already developed AI imaging and anomaly detection tools. For example, Google Health engineered systems able to uncover breast cancer with fewer false positives and negatives than human professionals (Google for Health, 2025). As AI slowly becomes more and more integrated into the practice of medicine, experts believe it will soon become an everyday clinical tool to improve patient experience and physician work. Dr. Robert Pearl, former CEO of The Permanente Medical Group, voiced, "AI will be as common in healthcare as the stethoscope.” While AI provides many utilitarian benefits, it also has its limitations. Furthermore, the increasing rise of AI in healthcare raises important questions about the safety frameworks and limits to how much these machine-learning tools can participate in healthcare while still retaining the human aspect of medicine. Government and medical organizations have voiced numerous critical risks AI integration poses, such as data privacy and security risks, lack of "human warmth and compassion," overreliance, and skill atrophy. Optimizing the benefits while moderating drawbacks from AI requires careful evaluation of it before widespread implementation (HITRUST, 2023). In overview, the application of AI in healthcare necessitates safety frameworks and limitations to ensure a safe workplace and healthy usage of this new tool in health services. In a study conducted by Wolters Kluwer titled “Generative AI: Balancing today’s needs and tomorrow’s vision,” they found that while 63% of medical personnel were eager to apply AI to their workflows, only 18% were aware of any regulatory policies or training at their institutions. Considering the benefits AI can bring to healthcare, we may revolutionize healthcare delivery for the public with its implementation of it. Despite all these advances, however, we must not forget the human touch that molded medicine. No matter how innovative the industry seems to be, AI should be kept as a tool, not a replacement for professional care. Just like the stethoscope, the power of algorithms can only act as an extension of the skill of the person wielding it. It will never become a substitute for years of studying and experience, the comfort given to despondent families, nor a person who can make complex ethical decisions that require empathy and professional judgement. Patient care is ultimately a responsibility that lies on the shoulders of medical experts, making humans vital to the practice of medicine. With regulation, ethical boundaries, and persisting human compassion, AI truly can become a valuable tool in not only forwarding healthcare, but also restoring and preserving the care in the heart of medicine.

Since its discovery in the brain, dopamine has been regarded by scientists as one of the brain’s most vital neurotransmitters. Though frequently portrayed in social media as a “pleasure hormone” or “reward molecule” [1], dopamine spans a range of processes beyond making us “feel good” and has important implications in neuroscience and in our everyday lives. Dopamine is a neurotransmitter synthesised from the amino acid phenylalanine [2] that is produced mainly in the midbrain of the brainstem. The midbrain is divided into two main regions: the ventral tegmental area (VTA) and the substantia nigra [1-4]. Dopamine neurons in these regions project to other brain regions, forming pathways (Figure 1) involved in a wide range of cognitive processes. For example, the mesolimbic pathway, which forms when dopamine neurons in the VTA project to the nucleus accumbens, plays a role in rewarding experiences, and the nigrostriatal pathway, which forms when dopamine neurons in the substantia nigra project to the dorsal striatum, plays a role in movement [1, 3-5]. Figure 1. Main dopamine pathways in the brain (Boggio et al. 2023) Dopamine binds to five different subtypes of dopamine receptors (D1, D2, D3, D4, and D5), activating a G protein. This triggers an increase or decrease in the concentration of the second messenger cyclic adenosine monophosphate (cAMP), depending on the receptor type (increase for D1 and D5 receptors, and decrease for D2, D3, and D4 receptors). In turn, this stimulates various cellular responses, such as the activation or deactivation of specific proteins that mediate various cognitive functions [1–3]. The most well-known cognitive function influenced by dopamine signalling tends to be the feeling of pleasure and reward [1,3]. However, it would be an oversimplification to say that dopamine makes us “feel good” during rewarding experiences. Dopamine is involved in reward prediction error (RPE), which is defined as the difference between the reward that is expected and the reward that is received [1, 3-5]. In other words, dopamine increases when a reward is better than expected, increasing the likelihood that future actions will be taken to obtain the reward again, and the opposite happens when the reward does not meet one's expectations [1,5]. An important finding regarding the role of dopamine in pleasure and reward is that when a reward is completely as expected, dopamine does not increase in response to the reward but rather in response to the reward’s cue [1,5]. This idea has become important in explaining the science behind addictive behaviors, such as excessive social media usage. On social media, cues such as notifications, messages, and likes increase dopamine by activating the mesolimbic pathway and satisfying the human need for social approval. It is important to note that these cues are unpredictable, as users cannot predict when they will receive a like. Previous research has determined that unpredictable cues tend to sustain long-term dopamine signalling compared to predictable cues and reinforce repeated engagement with social media, such as frequent checking. Another notable fact is that the cues are quantifiable, with a greater number of cues, such as more likes on a post, generally resulting in a greater activation of the mesolimbic dopamine pathway [5]. Beyond its role in pleasure and reward, dopamine also plays a vital role in voluntary movement [1,3]. This was demonstrated in the 1950s when Swedish neuropharmacologist Arvid Carlsson, the scientist who first discovered dopamine in the brain, inhibited dopamine transmission in rabbits, paralyzing the animals [1]. However, movement was restored when the rabbits were injected with L-DOPA, a precursor molecule used in the synthesis of dopamine [1,2]. This experiment formed the basis of understanding the role of dopamine in movement and led to the hypothesis that the movement-related symptoms of Parkinson’s Disease (PD), such as tremors, may be due to the death of dopamine neurons in regions of the brain, such as the substantia nigra [1–3]. Additionally, dopamine plays a role in working memory, emotions, endocrine function, gastrointestinal function, immune responses, and higher-level cognitive processes [1-3]. Dopamine is also often thought of as a “neuromodulator” that is directly or indirectly involved in nearly every cognitive function that occurs in the central nervous system and various functions that occur in the peripheral nervous system [1–4]. In overview, dopamine is far more than a “pleasure or reward chemical” and has important implications in medicine and in our daily lives. Research into dopamine has been pivotal in developing medical interventions against various neuropsychiatric disorders, such as Parkinson’s Disease, schizophrenia, and substance use disorder, and in better understanding the day-to-day actions and habits that define us as humans.

When you hear the word scoliosis, you might picture someone with bad posture or a heavy backpack. In reality, it is neither of these things. Scoliosis is a condition in which the spine curves sideways and often twists, forming an “S” or “C” shape instead of appearing straight. As someone living with scoliosis myself, I know how easy it is for people to misunderstand the condition or assume it is caused by poor posture. However, learning more about it has shown me that there is so much more to scoliosis than many people realize. While mild cases may go unnoticed, roughly 2-4% of teenagers worldwide are affected by scoliosis, making it one of the most common spinal conditions in teenagers. Because it often develops during puberty due to rapid growth spurts, understanding scoliosis can help young people understand and recognize early signs to seek appropriate care when needed. Figure 1. Measuring the Cobb Angle A healthy spine is designed to look straight when viewed from behind. However, in scoliosis patients, the spine curves sideways, usually by 10 degrees or more. This is a measurement known as the Cobb angle. In many cases, the spine also rotates, causing a shoulder blade or a side of the rib cage to appear more prominent than the other. There are several types of scoliosis, but the most common is adolescent idiopathic scoliosis (AIS). AIS affects 1-3% of children in the population, with those aged 10-15 years. The word idiopathic means that the exact cause is unknown. Although researchers believe genetics may play a role because scoliosis runs in families, no single cause has been identified yet. Scoliosis usually develops rapidly between the ages of 10 and 18. Many teenagers do not experience pain, and they only begin to notice its symptoms when one shoulder begins to sit higher than the other, clothes fit unevenly, or an adult notices a significant change in posture. To diagnose scoliosis, a doctor may perform a simple physical examination called the Adam’s Forward Bend Test, where the patient bends forward while the doctor checks for unevenness in the back. If scoliosis is suspected, an X-ray is used to measure the Cobb angle and determine how severe the curve is. Treatment depends on several factors, including the size of the curve, the patient’s age, and whether they’re still growing. Small curves are often monitored with regular checkups to ensure they do not worsen. Moderate curves in growing teenagers may be treated with a supportive brace that the patient must wear during the day (typically 10+ hours and, in severe cases, up to 23 hours) and may be recommended to partake in physiotherapy, which strengthens muscles and improves posture. Surgery is usually considered only for severe curves that continue to worsen despite other treatments. The most common surgery is called a spinal fusion, involving straightening the spine using metal rods and screws, then ‘welding’ the curved bones together with bone grafts so they heal into a single solid piece. Figure 2. A Scoliosis Brace Figure 3. Spinal Fusion Surgery Results As mentioned earlier, scoliosis is most commonly diagnosed during adolescence, making it especially relevant for students. One of the biggest misconceptions regarding scoliosis is that it is caused by carrying a heavy backpack or having poor posture. However, in reality, these factors cannot directly cause scoliosis. While carrying a bulky backpack can lead to temporary back pain, it does not change the shape of the spine, while having bad posture could be a symptom of scoliosis. Having scoliosis does not mean someone cannot live an active life. Many teenagers with scoliosis continue to participate in sports and engage in other physical activities. Indeed, staying active is often encouraged because it helps maintain muscle strength, overall flexibility, and well-being. At the end of the day, understanding scoliosis can help dismantle these common misconceptions about it and remind us that a curved spine does not define a person’s abilities or potential. Although scoliosis may sound intimidating, it is a common condition that many young people successfully manage. Writing this article as someone with scoliosis has reminded me how important awareness is, as understanding the condition is the first and most important step towards replacing misconceptions with the facts and supporting those around you living with this condition. With regular monitoring, appropriate treatment, and continued physical activity, most teenagers with this condition (including me!) can still live healthy and active lives. References Jo, H.

Imagine a physically fit individual. What comes to mind? For most people, it is someone who is slender and has healthy hair, nails, and teeth. Yet, the fundamental determinant of fitness is almost always overlooked: proper nutritional intake. Nutrition builds the foundation of one's overall health, supplying them with the necessary nutrients to function. Neglecting to consume meals with proper nutritional value for one’s body type can result in hair loss, teeth decay, inhibited growth of nails and bones, and many other ailments that affect the internal processes of the body. The hectic urban life has made the average person increasingly susceptible to nutritional deficiencies. This is primarily because the majority of people choose to consume fast food over home-cooked meals, owing to its cheapness, convenience, and accessibility. Furthermore, fast food is primarily composed of sodium, sugars, and fats [1] which contribute to their addictive nature, making them easy to over- consume. Consequently, an alarmingly high number of individuals are at an increased risk of developing chronic diseases, such as obesity, diabetes, hypertension, and cardiovascular disease [2]. Despite this, nutritional deficiency is often perceived as having a single, universal image—the emaciated figure portrayed in textbooks. This misconception reiterates the stigma surrounding individuals who appear either physically ‘fit’ or ‘overweight,’ discouraging them from acknowledging or seeking help for nutritional deficiencies. Malnutrition can affect individuals across the body-weight spectrum, from those who appear physically fit to those who are obese. Approximately 2 billion ‘obese’ people are classified as ‘malnourished’ [3], as diets high in ultra-processed foods provide ample energy but insufficient essential vitamins, minerals, and other nutrients. Similarly, individuals who appear physically fit may also experience malnutrition, often by engaging in harmful and/or restrictive diets without professional guidance. For instance, ketogenic diets have been shown to lower blood levels of triglycerides and increase LDL cholesterol in individuals [4]. Even many athletes, who are hailed as the pinnacle of physical fitness, are reported to face forms of malnutrition, namely relative energy deficiency and micronutrient deficiencies. This is largely due to their diet comprising high glycemic foods, excess omega-6 lipid consumption [5], and insufficient energy intake relative to training demands, as well as inadequate intake of essential micronutrients. Raising youth awareness of this issue is critical, as dietary guidance for adolescents in their formative years can create lifelong habits. Numerous studies underscore the importance of adequate nutrient intake during adolescence for optimal physical and cognitive development. Maintaining a balanced diet, eating regular meals, undergoing routine medical check-ups and blood tests when appropriate, and engaging in regular physical activity are all practical measures that can help individuals monitor and improve their nutritional status. In a society that equates health with appearance, it is indispensable that young people remain aware of their nutritional needs over physical aesthetics. At the end of the day, good nutrition should not be judged by appearance alone but by whether the body's physiological needs are being adequately met. References 1.

For much of modern medical practice, treatment has focused on managing disease rather than eliminating underlying causes. While advances in pharmacology and surgical intervention have significantly improved survival and quality of life across a range of conditions, many genetic disorders remain fundamentally incurable, requiring lifelong management instead. However, in recent years, emergent gene-editing technologies have been challenging this paradigm. CRISPR-based systems now enable targeted modifications of DNA, the molecular substrate of heredity. Once regarded as a theoretical or experimental tool, gene editing has progressed rapidly toward promising clinical applications. Its emergence represents a potential shift in medicine from symptomatic treatment towards genetic-level intervention, with implications spanning inherited disease, oncology, and regenerative medicine. DNA encodes the biological instructions required for cellular function and organismal development. These instructions are organized into genes, which direct the synthesis of proteins that regulate nearly all physiological processes. Mutations in the DNA sequence can alter protein structure or expression, contributing to disease development. Gene-editing technologies such as CRISPR-Cas9 have enabled direct intervention at the microscopic level of the genome. Derived from a bacterial adaptive immune system, CRISPR uses a guide RNA to direct a nuclease to a specific genomic location. Once bound, the enzyme introduces a double-stranded break in DNA, which can then be repaired through cellular mechanisms that allow for targeted disruption or correction of genetic material. This approach has translated into clinically relevant therapies. In 2023, the first CRISPR-based treatment for sickle cell disease received regulatory approval. Sickle cell disease results from a mutation in the HBB gene, which encodes a specific subunit of hemoglobin. The mutation leads to the production of structurally abnormal hemoglobin, resulting in deformed erythrocytes and subsequent vascular occlusion. Gene-editing approaches targeting important hematopoietic stem cells can restore more typical hemoglobin expression levels, reducing disease severity in the affected individual. Ongoing research is extending these methods to additional conditions, including inherited retinal disorders, primary immunodeficiencies, and certain malignancies. While clinical translation remains limited to a small number of approved therapies, the field is advancing rapidly and is increasingly situated within a vast framework of precision medicine. The implications of gene editing extend beyond specialized clinical settings, particularly since many genetic disorders manifest during childhood and adolescence. Advancements in this field may therefore alter the long-term prognosis for conditions that are currently chronic and progressively debilitating. At the same time, however, this expansion of genetic medicine does introduce complex ethical and societal considerations. The boundary between therapeutic intervention and enhancement remains scientifically and philosophically contested. Questions regarding equitable access, long-term safety, and appropriate regulatory oversight remain unresolved and will likely require sustained engagement from both scientific and public stakeholders. For younger populations, these developments are particularly relevant not only as potential patients, but also as future researchers and participants in scientific, medical, and public policy. In conclusion, gene-editing technologies represent a significant development in contemporary biomedical science, with the potential to fundamentally alter the treatment of genetic disease. While early clinical successes have demonstrated clear therapeutic promise, the field remains in an early stage of translation, with substantial technical, ethical, and regulatory challenges still to be addressed. As genetic medicine continues evolving, its ultimate impact will depend not only on scientific progress but also on the frameworks established to guide its responsible application in clinical practice.

Ageism comes in many different shapes and forms. Ageism can range from inadvertently avoiding eye contact with older adults to refusing to provide healthcare services to the elderly. Regardless of the severity of the discrimination, understanding how societal prejudices affect healthcare delivery is essential in creating a safe healthcare ecosystem for all generations. Image: Designed on Canva A Nature report from 2025 found that ageism affects older patients physiologically, psychologically, and behaviorally. Take a look to find out more about how ageism affects healthcare outcomes! Effects of Healthcare Experimental Conditions Results Physical Effects The study used vagally mediated HRV (heart rate variability) as a measurement of physical health, since a low HRV score has been associated with stress and cardiovascular mortality in other stigmatized groups. Among the 64 elderly participants in this experiment, those who experienced healthcare discrimination had a larger decrease in HRV than those who did not. Psychological Effects The study examined the relationship between patient trust and psychological health. The elderly who experienced discrimination had lower levels of trust in the healthcare provider than the elderly who did not experience discrimination. Behavioral Effects Previous studies reported that victims of discrimination were much more likely to take part in "unhealthy behaviors," such as substance abuse, sleep deprivation, and avoiding regular medical checkups. There was increased avoidance of the experimental healthcare worker in the elderly who experienced ageism.  Although this study alone cannot account for all of the possible consequences of ageism in healthcare, it shows a glimpse of how one's personal biases can, and do, interfere with healthcare delivery. How Is This Relevant To Teenagers? There is a very common misconception regarding ageism: ageism only affects the elderly.  However, this belief could not be farther from the truth. In reality, children, even those who do not yet have the words to describe this bias, internalize ageism from as young as 4 years old. As a result, these biases eventually form the worldview from which children perceive others and themselves.  Ageism can also affect young adults and teenagers (like you and me)! Ageism exists in the workplace, where there are implicit social hierarchies that limit young employees' roles. Ageism exists in young adults who are afraid to take risks, simply because they have been taught that they are too "old" to change routes. Image: Designed on Canva Truly, this issue is not limited to one sector, one country, or even one generation. Ageism has seeped into every crevice of our lives, impacting both the 1.4 billion elderly in the world and the other 6.9 billion who have also been affected by the cycle of ageism. Ageism is not only a healthcare issue but also a societal one that dismantles the trust between generations. What Can I Do to Combat Ageism in Healthcare? Now that we understand the widespread and destructive nature of ageism, what can we, as teenagers, do to combat such issues? Here is a list of several action items that can promote societal change. Advocate for laws that promote fair healthcare delivery for all age groups. In the United States, high school students can intern with paralegals or attorneys. In these internships, teenagers can attend trials and organize service programs in their local community.  Although youth advocacy may have its limits (e.g., having a hard time finding others who support your cause), teenagers are at a unique stage of life that allows them to connect with both adults and children.  Raise awareness of ageism.   Whether you believe it or not, a simple speech uploaded to YouTube, spoken to your classmates, or posted on your medical blog (just like I did!) can illuminate the detrimental consequences of practicing ageism.  Raising awareness both helps individuals recognize the significance of this issue and motivates them to proactively reform their unconscious biases.  Connect with individuals from different walks of life.  Teenagers are at the cusp of childhood but still a step away from adulthood. This unique standing provides them with the social skills to communicate with the elderly and the long-term thinking skills that allow them to teach children the dangers of ageism.  Overcoming biases is a two-way street; it requires the "teacher" to show compassion to those who are biased, but also the "student" to learn how detrimental biases can be. Embrace being in the position of both a teacher and a student. All in all, ageism is not an issue that can be solved overnight. However, youth advocacy can bridge communities from all walks of life.

As a high school junior, I know how overwhelming life can feel when you have a million tasks on your to-do list. Although many teens realize that asking for mental health guidance is OK, I can definitely relate to trying to hide my struggle with anxiety, issues at home, or overthinking. Yet, since October is the month of Mental Health Awareness, I wanted to open up the discussion on how mental health stigma affects teens today. Let's find out today 🧠 Image: Designed on Canva Primary types of mental health disorders Affecting about “one in seven 10-19-year-olds” worldwide, mental health issues are both widespread and have long-lasting impacts on their health. The following table, referencing data from the World Health Organization, exemplifies the various types and symptoms of psychological disorders. Type of Disorder Examples What can happen if it is untreated Statistics Emotional disorders Anxiety disorders, depressive disorders Suicide, decreased school performance, and social isolation Anxiety disorder affects around 4.1% of 10 to 14-year-olds and 5.35 of 15 to 19-year-olds. Behavioral disorders Attention deficit hyperactivity disorder, conduct disorder Increased probability of committing a crime, decreased school performance ADHD affects around 2.7% of 10 to 14-year-olds and 2.2% of 15 to 19-year-olds Eating disorders Anorexia nervosa, bulimia nervosa Suicide, premature death Eating disorders affect 0.1% of 10 to 14-year-olds and 0.4% of 15 to 19-year-olds. Psychosis Hallucinations, schizophrenia, delusions Stigmatized by society, difficulties in daily life, and education Psychosis affects 0.1% in 15-19 year olds Scientists typically attribute these disorders to exposure to risk factors , which in this case are primarily experiences that increase an individual's chance of having a mental illness. Ranging from childhood abuse to lack of mental health guidance, these risk factors may affect how teenagers respond to mental health issues . Mental Health Stigma Now we know the types of mental health disorders, but here’s the real question: why is it that most teenagers don’t ask for help? Let’s take a look at a study from the Stigma and Health Journal. Image: Lyra Health This study broke down stigma into 4 major categories: labeling, stereotypes, separation, and discrimination. Labels are recognition phrases that divide those with and without mental health issues. While most may have the preconception that labels are inherently bad , that is not always the case. For instance, self-labeling can help teens reach out for help, especially if they believe they have a condition that needs professional guidance. Yet, it is true that labels with negative connotations may lead to internalized feelings of stigma. As a result, some teenagers may avoid labeling their conditions entirely , simply due to the potential of stigma affecting other aspects of their lives, such as social relationships or personal reputation. What's more, participants of the study tended to distance themselves from those with severe mental health disorders, displaying the cycle of stigma that continues to exist today. What can I do as a teenager? With suicide being one of the primary causes of death among adolescents, professional intervention in this cycle is critical. As a teenager reading this article, you can also do several things to speak up about this issue! Image: Lyra Health Have (deep) conversations with people you trust. Everyone has things they don’t talk about, whether that is family conflict or seasonal depression. By a llowing yourself to be vulnerable to those you trust, you will not only build more authentic relationships but may also find yourself with sage advice. So, take the first step in having a deep conversation with a friend today. Share how you seek help. You don’t have to tell everyone in your high school that you go to counseling or therapy (unless you want to, of course). Taking one step is just as brave as a grand gesture. Sharing how you are seeking professional help for your mental well-being can open up the discussion on mental health issues and encourage a classmate or family member to also try counseling. Image: Designed on Canva If you find yourself in a group of individuals passionate about mental health, educate your community on mental health. Refer to local psychiatric services or even your guidance counselors at school to find out ways you can contribute to mental health literacy. Attend mental health conferences to gain an even deeper understanding of the underlying causes of mental health illnesses By making your local community aware of the importance of mental health, you can reach students who, despite having a smile on their faces, may have been struggling with stress or coping mechanisms. Share outside resources that discuss teen mental health. As I share posts that normalize the discussion of stigmatized health conditions through the Med Tales, you, too, can make mental health a norm, not a taboo. Share some of these awesome mental health videos with a classmate today!

For most teens, stress hits close to home (especially if you are balancing school and any kind of sleep schedule)! That’s why whenever teens think about stress, they may typically imagine themselves pacing the night before a big presentation or anxiously shaking their legs during an exam. However, stress is not always a curse! In fact, stress is an evolutionary mechanism that enabled our ancestors to survive and learn from experience. Today, let’s explore how stress manifests in our bodies and how to recognize these signals ! Types of Stress Stress is a natural phenomenon that occurs when you are faced with stressors , a term referring to any challenges or changes in your environment. There are three main types of stress. Acute stress Short-term stress from a specific event/period, typically associated with positive or  negative emotions Example: Riding a rollercoaster Episodic acute stress Regular stress that arises when your lifestyle and/or obligations limit the time or resources to calm down Example: Working at the Emergency Department and not having time to unwind Chronic stress Long-term stress that extends for weeks or months Example: Financial problems leading to stress that lasts for 3-4 months When your body recognizes a stressor, your adrenal gland releases hormones , including cortisol, epinephrine (AKA adrenaline), and norepinephrine, into your bloodstream . This release leads to various responses from your body, ranging from increasing your heartbeat to disrupting the lining of blood vessels (known as the endothelium). In the meantime, the brain activates the sympathetic nervous system , a part of a bigger system referred to as the autonomic nervous system. While the autonomic nervous system is largely responsible for regulating one’s breathing, heart rate, and vision, the sympathetic nervous system particularly homes in on your “fight-or-flight” response. The “fight-or-flight” response leads to your body subconsciously enlarging your pupils and slowing down digestion to help you survive in dangerous situations. Physical Manifestations of Stress While stress is a critical survival mechanism that can save in life-or-death situations, chronic stress may lead to serious consequences, impacting your physical, psychological, and behavioral health . There is a side-by-side comparison down below! Physical side effects Psychological side effects Behavioral side effects Headaches Anxiety Eating disorders Sleep deprivation Sadness Substance abuse Hypertension Panic attacks Smoking Digestive problems Depression Internet use addictions Long-Term Consequences of Stress Although temporary stress may help you during your SAT or a big home game to focus, prolonged stress can lead to bigger problems over time. For one, your immune system can weaken, leading to slower healing times or increasing your chances of being infected . Your cardiovascular system might also be compromised, increasing your risk for high blood pressure . Chronic stress can also affect your appetite . Since cortisol tends to increase your appetite, you are naturally drawn to consume carb-heavy foods . This can lead to visceral fat , a type of body fat that releases hormones and chemicals typically associated with insulin resistance. From a bird’s eye view, stress can even affect how long your life is . Telomeres, the caps at the ends of chromosomes, naturally shorten with age. However, with additional stress, these telomeres can shorten faster ! Without telomeres, cells cannot divide, leaving you just enough time before your body eventually deteriorates. However, because there is no objective measure of stress, healthcare professionals often 1) have a hard time diagnosing stress and 2) prioritize tackling the physical symptoms before understanding the root causes behind your stress. My Point-Of-View As a high-school student, I know how hard it can be to manage social relationships, academic diligence, and sleep at the same time. To be honest, I am not immune to stress either. Some days, I curl up and do nothing all day, while on other days, I feel confident after writing three essays. Don’t think there is a uniform “path” for everyone. You can go at your own pace , so trust that you’ll find your own way. Final Words Stress is an inevitable part of life that you cannot control, but what you can control is how you choose to respond to and manage stress. According to the Cleveland Clinic, mental health is inextricably tied to your physical health, so I encourage you to get some exercise—whether it is a stretch or a full-body workout—to help your brain register that it is not in danger. By setting goals and healthy boundaries, you can overcome this very stressful period of being a teenager. Always know that if you feel overwhelmed or burnt out, you can reach out for help through your school counselors or therapists. If you are considering inflicting self-harm, please reach out to your local crisis lifeline.

You might hear E. Coli and think it’s some mysterious, fatal disease that you’ve never encountered before. In reality, E. Coli is a bit like celebrities: lots of people have strong opinions or misconceptions about it! Today, let’s break down what E. Coli really is, the risks associated with it, and steps you can take to prevent outbreaks. Image: Harpeth Conservancy What is E. Coli? The full name of E. Coli is Escherichia coli . It’s a single-celled organism that lives in the colons of warm-blooded animals. In other words, it is a coliform bacterium . 👍 The Pros Most strains of E. Coli are actually innocuous and even helpful in the gastrointestinal tract. In your gut, E. Coli plays a role in digesting food, assembling vitamins, and fighting off harmful toxins. It is also one of the few gut bacteria that can exist under oxygen . You can think of E. Coli as a superhero for your gut, absorbing up all of the oxygen so the rest of your microbiome environment can thrive! Image: Science Photo Library Additionally, E. coli has been a “model organism” for scientists for decades. Knowledge about key information regarding DNA, including codons and gene expression, can be attributed to the experiments on the K-12 strain of E. Coli. 👎 The Cons But E. Coli isn’t always your superhero. Image: Marler Clark Because E. Coli is also released in the feces of warm-blooded animals , it can reach water systems through leaky sewer pipes, poor septic systems, or runoff from manure and wildlife. Some strains of E. Coli are pathogenic, meaning they cause illness. Yet, even non-pathogenic strains can cause trouble when consumed in contaminated food or water. Potential consequences of an E. Coli infection include: Pneumonia Sepsis Hemolytic uremic syndrome (HUS) - a dangerous condition where inflamed blood vessels lead to clots that can damage the kidney and other organs. Children and those with weak immune systems are especially vulnerable! 🦠 How does E. Coli Attack? E. Coli releases toxins into intestinal cells, telling them to either stop absorbing water or release more water (which leads to diarrhea). Symptoms usually appear 3-4 days after exposure and last about 5-7 days. Most people can recover with the right resources, but if the disease progresses, don't hesitate to get in touch with your local healthcare provider ! 🩺 Precautions Image: Designed on Canva The U.S. Centers for Disease Control and Prevention (CDC) recommends some simple habits that can prevent an E. Coli infection: Wash your hands, utensils, and surfaces (especially before cooking or eating) Separate raw and cooked food Place perishable food in the refrigerator (within 2 hours) Use a food thermometer to check that your meals are safely cooked ⭐️ I hope you learned something new about E. Coli, our gut health’s superhero and occasionally, our archnemesis!
