#ADHD

A new study published in Trends in Cognitive Sciences is shedding light on a phenomenon everyone from Thai university students staring at exam papers to harried Bangkok office workers can relate to: the mind suddenly, inexplicably going blank. Once lumped in with mind wandering, “mind blanking” has now been described by neuroscientists as a unique and measurable state linked not just to daydreaming or boredom, but to specific changes in the brain, body, and levels of alertness. The findings carry important implications for how we understand everyday lapses—along with clinical conditions like anxiety and ADHD—for people in Thailand and around the world.

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 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).

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).

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.

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.

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.

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.

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.
