Groundbreaking research published this month in Nature Communications has upended a long-standing assumption in neuroscience: contrary to the traditional view, our visual cortex doesn’t act as a passive camera that merely records the world for later analysis. Instead, it actively tunes how we see, adjusting perception in real time to align with what we’re trying to do at any given moment. This insight, highlighted in a recent article by MedicalXpress, provides a vivid new understanding of how our brains flexibly interpret the world depending on our current objectives—whether that means preparing a winter stew or hosting a Super Bowl party, as the study’s lead author, Dr. Nuttida Rungratsameetaweemana, describes in a relatable example (source: https://medicalxpress.com/news/2025-04-purpose-visual-cortex-tunes-perception.html).

A new study in Nature Communications challenges the idea that the visual cortex merely records the world. Instead, it actively tunes perception in real time to fit what we’re trying to do at any moment. Researchers highlight that even simple shapes are processed differently depending on our objectives. In practical terms, your brain’s visual system flexes to help you achieve your current goal, whether you’re selecting the right mango at a market or solving a classroom puzzle.

A rising number of families feel overwhelmed by the search for the most suitable therapist for their children, especially when ADHD-related behaviors create urgent stress at home. This was the focus of a recent episode on Slate’s Care and Feeding podcast, where a mother described the draining cycle of trial after trial in search of support for her daughter. The episode underscores a broader trend now gaining attention in research and news: therapy shopping—the demanding, time-consuming hunt for effective mental health care.

A growing number of parents are finding themselves overwhelmed and exhausted by the search for the “right” therapist for their children—especially for conditions like ADHD, where behavioral outbursts can create urgent family stress. This was the central story in a recent episode of Slate’s “Care and Feeding” parenting podcast, where hosts responded to a mother tired by seemingly endless therapy trials and the ongoing struggle to find support for her daughter’s behavioral needs. Her dilemma reflects a wider phenomenon now drawing attention in new research and news: ‘therapy shopping’—the often stressful, confusing, and time-consuming search for effective mental health care—is exacting a heavy toll on families everywhere (Slate Podcast).

Rejection can sting for anyone, but some people react as if every slight is deadly. This phenomenon, known as rejection sensitivity dysphoria (RSD), has gained prominence through social media, evolving research, and personal accounts. A recent feature in a leading international publication uses real stories, clinical insight, and emerging science to explore a condition not yet common in medical textbooks but increasingly discussed by mental health professionals worldwide, including among Thai youths.

For many Thais, rejection—whether from friends, family, or colleagues—can feel like a sting, but for some, even the smallest slight feels devastating. This overwhelming emotional reaction, described as “rejection sensitive dysphoria” (RSD), is gaining attention thanks to social media, research, and a wave of first-person accounts. The latest article from The New York Times draws on real-life stories, clinical insight, and emerging science to examine a phenomenon seldom found in medical textbooks but increasingly recognized in the mental health community, including among younger generations in Thailand and worldwide (source: The New York Times).

Rejection Sensitive Dysphoria (RSD) has returned to the spotlight, with researchers and advocates describing how even minor criticism can trigger sudden, overwhelming distress. The New York Times highlighted RSD as a condition where perceived rejection can plunge individuals into deep sadness, rage, or worthlessness, making the world feel unstable.

For Thai readers, this renewed attention matters as mental health awareness grows amid lingering stigma. RSD is closely linked with ADHD and other neurodivergent experiences, but recent studies show its impact reaches beyond diagnosed groups, affecting daily life and self-esteem in many people. Data from leading health researchers indicate higher rejection sensitivity among those with mood disorders and anxiety, underscoring the need for broader recognition and support.

In recent months, the term “Rejection Sensitive Dysphoria” (RSD) has gained renewed attention in both scientific literature and popular media, as mental health experts and affected individuals speak out about this intense emotional condition that can turn minor criticisms into catastrophic emotional reactions. The New York Times recently profiled RSD, describing the condition as a state where even slight rejection, teasing, or criticism triggers a rapid plunge into feelings of profound sadness, rage, or worthlessness, making sufferers feel as if “the world is collapsing” around them source.

A wave of online discussion and emerging expert commentary has thrown the spotlight on a little-known but deeply felt emotional response that many people with attention deficit hyperactivity disorder (ADHD) are now recognizing as a shared experience: rejection sensitive dysphoria (R.S.D.). Although not officially classified in psychiatric manuals, R.S.D. is described as an intense or overwhelming reaction to actual or perceived criticism, rejection, or failure—a feeling likened to a “balloon popping” by TikTok creators and capturing the imagination of millions on social media platforms source.

A growing online conversation and expert commentary are bringing attention to rejection sensitive dysphoria (R.S.D.), a powerful emotional response some people with ADHD experience when facing criticism or perceived failure. Although not yet a formal diagnosis in major manuals, ADHD communities describe R.S.D. as an intense, sudden shift in mood—like a balloon popping—triggered by real or imagined rejection. This topic has captivated millions on social media and sparked wide conversations about mental health.

The bustling world of A.D.H.D. diagnosis and treatment has come under fresh scrutiny as new research questions long-held beliefs about the disorder’s nature and treatment. A detailed New York Times article by Paul Tough, “Have We Been Thinking About A.D.H.D. All Wrong?,” dives deep into the evolving understanding of Attention Deficit Hyperactivity Disorder (A.D.H.D.) and how it is frequently addressed through medical treatments, challenging the current paradigm with emerging scientific insights.

Attention Deficit Hyperactivity Disorder (ADHD) is undergoing re-examination as new research questions long-held assumptions about its nature and treatment. A recent New York Times piece by Paul Tough, Have We Been Thinking About ADHD All Wrong?, probes how the disorder is identified and managed, challenging prevailing approaches with fresh scientific insights.

ADHD diagnoses rose sharply in recent decades, from about 3% of American children in the early 1990s to roughly 11% today. The surge coincates with the 1990s, when stimulant medications such as Ritalin became widely prescribed. The landmark Multimodal Treatment of ADHD (MTA) study initially supported stimulant use for symptom relief. Yet long-term follow-ups raised questions about the durability and scope of medication benefits, with researchers including psychologist James Swanson highlighting evolving concerns.

A comprehensive meta-analysis published in a leading medical journal reveals a notable association between maternal diabetes during pregnancy and a higher risk of neurodevelopmental disorders in offspring, including autism and ADHD. The large study pooled data from hundreds of studies and millions of pregnancies, emphasizing the importance of diligent blood sugar monitoring for expectant mothers to improve outcomes for babies.

Researchers distinguished between gestational diabetes, which arises during pregnancy, and pre-gestational diabetes, in which the mother already has type 1 or type 2 diabetes. The analysis found about a one-quarter to one-third increase in neurodevelopmental risks for children born to mothers with diabetes, even after adjusting for factors such as weight and socioeconomic status. The elevated risk was more pronounced for women with pre-existing diabetes than for those who develop gestational diabetes.

A major international analysis published in The Lancet Psychiatry finds that ADHD medications generally cause only minor cardiovascular effects, mainly small increases in heart rate and blood pressure. The study, led by researchers from the University of Southampton, reviewed data from 102 clinical trials involving more than 22,700 participants worldwide. It compared stimulant and non-stimulant ADHD treatments, concluding that while small heart-related changes occur, the overall benefits of these medicines often surpass the risks.

A comprehensive new analysis, published in The Lancet Psychiatry, underscores that medications prescribed for attention-deficit/hyperactivity disorder (ADHD) generally induce minor impacts on cardiovascular health, mostly characterized by slight elevations in heart rate and blood pressure. Conducted by an international team led by the University of Southampton, this large study evaluated data from 102 clinical trials involving over 22,702 participants globally, comparing both stimulant and non-stimulant medications used to treat ADHD. The news from this research provides a balanced view, suggesting that while there are small cardiovascular effects, the broader benefits of these medications often outweigh such risks.

A growing wave of health experts suggests a simple habit could sharpen focus and energy at work and school: a dopamine menu. Rather than aimless scrolling during breaks, Thai professionals and students can benefit from short, purposeful activities that refresh the brain and reset attention.

A dopamine menu is a brief list of easy actions that raise dopamine—the brain’s “feel-good” chemical linked to mood, attention, reward, and motivation. The concept comes from behavioral activation, a psychology approach that helps people start beneficial tasks even when motivation is low. Instead of passive distractions, the recommended breaks involve quick actions like a short walk, listening to music, petting a pet, or brewing a cup of tea.

In the whirlwind of modern work life, maintaining focus on challenging tasks can often feel insurmountable, especially for those in high-stress roles. A recent insight from the Mayo Clinic Executive Health suggests an innovative approach to this persistent issue: the “dopamine menu.” This concept is designed to rejuvenate mental energy and redirect focus by integrating strategically chosen breaks into the daily grind. It’s an intriguing development with meaningful implications for Thai professionals and students alike.

In an age where mental health awareness is at an all-time high, a new perspective from neuropsychiatrist Dr. Alastair Santhouse raises thought-provoking questions about the potential over-diagnosis of mental health conditions. Dr. Santhouse’s recent book, No More Normal: Mental Health in an Age of Overdiagnosis, argues that while mental health awareness is undoubtedly beneficial, it might also be leading more people to identify with symptoms that may not necessarily qualify as mental disorders. For Thai readers, understanding this global conversation is crucial in navigating local mental health discourses.

A new perspective from neuropsychiatrist Dr. Alastair Santhouse challenges readers to consider whether mental health awareness is veering into over-diagnosis. In his book No More Normal: Mental Health in an Age of Overdiagnosis, he argues that while raising awareness is vital, it may also prompt more people to identify with symptoms that do not meet clinical criteria. For Thai audiences, this global discussion has meaningful local implications for how mental health is understood and treated.

In a groundbreaking study, researchers employing virtual reality (VR) and functional MRI have unveiled distinct neural communication patterns in children with ADHD, diverging significantly from traditional methods that focus on resting brain states. Conducted by a collaboration of European universities, including Aalto University, the research underscores the potential of dynamic diagnostic methods and gamified tools in transforming ADHD diagnosis and treatment.

ADHD, or Attention Deficit Hyperactivity Disorder, remains a prevalent condition affecting many Thai children, characterized by symptoms such as inattention, hyperactivity, and impulsivity. Current diagnostic practices often rely on static brain imaging, which fails to capture the nuances of how these symptoms manifest in real-world interactions. This study marks a significant pivot towards understanding ADHD as an active neurodevelopmental disorder, where the brain’s interaction with the environment becomes a crucial diagnostic element.

A European partnership using virtual reality and functional MRI maps how children with ADHD communicate during active tasks, not just at rest. The study points to dynamic diagnostic methods and gamified tools that could reshape ADHD identification and treatment. For Thai readers, the findings suggest practical ways to tailor classroom and clinical interventions.

ADHD, or Attention Deficit Hyperactivity Disorder, affects many Thai children and is characterized by inattention, hyperactivity, and impulsivity. Traditional assessments often rely on static brain imaging, which misses how symptoms unfold in real-life interactions. The research frames ADHD as a neurodevelopmental condition shaped by environmental engagement, offering a more holistic diagnostic perspective.
