A new review has shed light on why people living with obsessive-compulsive spectrum disorders (OCSDs), chronic tic disorders (CTDs), and attention-deficit/hyperactivity disorder (ADHD) often experience pronounced sleep disturbances—as well as how these intertwined problems could one day be better managed. The research, recently published in the Harvard Review of Psychiatry and summarised by several neuroscience outlets, finds that disruptions in a crucial brain circuit, the cortico-striatal-thalamo-cortical (CSTC) pathway, underpin both the psychiatric symptoms and the insomnia, delayed sleep onset, and other sleep issues reported in these populationsNeuroscience News.

A new review explains why people with obsessive-compulsive spectrum disorders (OCSDs), chronic tic disorders (CTDs), and ADHD often suffer from sleep disturbances, and how these issues might be better managed in the future. The study, highlighted by neuroscience outlets and summarized in academic journals, points to disruptions in a brain network called the cortico-striatal-thalamo-cortical (CSTC) circuit as the underlying mechanism for both psychiatric symptoms and insomnia, delayed sleep onset, and related sleep problems.

Thailand, like many countries worldwide, is witnessing increased public concern as reported cases of autism rise steeply each year. However, recent research and leading international experts contend that this apparent surge in autism diagnoses may not reflect a true rise in the prevalence of autism itself, but rather the product of social, medical, and diagnostic transformations over recent decades (BBC).

The significance of understanding these trends cannot be understated for Thai parents, educators, and healthcare professionals. Against a backdrop of growing public discussion and sometimes anxiety over neurodevelopmental disorders, clear and accurate information about autism spectrum disorder (ASD)—its causes, diagnosis, and support—remains critical for societal awareness, policy planning, and resource allocation.

Public concern about autism is rising in Thailand as diagnoses increase each year. Experts say the uptick is not necessarily a true increase in autism itself, but the result of social, medical, and diagnostic changes over the past decades. Research from international institutions suggests that greater awareness, improved screening, and evolving criteria are driving more children into diagnosis.

Understanding these trends is essential for Thai parents, teachers, and healthcare professionals. Clear, accurate information about autism spectrum disorder (ASD)—its causes, diagnosis, and support—helps with policy planning, resource allocation, and reducing anxiety around neurodevelopmental differences.

In a groundbreaking study published in The Lancet, Chinese researchers have unveiled a significant association between maternal diabetes during pregnancy and an elevated risk of neurodevelopmental disorders like autism and ADHD in children. This extensive meta-analysis evaluated 202 studies encompassing over 56 million pregnancies. It reveals that diligent monitoring of blood sugar levels throughout pregnancy could be crucial in mitigating these risks, underscoring a vital public health message for expecting mothers.

A new study from UC Santa Cruz and UC San Francisco reveals that neurons may be more adaptable than once thought. Published in iScience, the research demonstrates that certain neurons can change their type in response to environmental cues. The findings challenge the long-held belief that neuronal identity is fixed after differentiation. Data from advanced 3D brain models, known as cerebral organoids, underpin this breakthrough and point to transformative possibilities for neurodevelopmental research.

In a pioneering study, researchers from UC Santa Cruz and UC San Francisco have overturned traditional neuroscientific tenets by demonstrating that neurons, the cellular pillars of brain activity, exhibit far greater plasticity than previously acknowledged. Published in the journal iScience, this research unveils the startling ability of certain neurons to transform type in response to their environment, a finding that could revolutionize our understanding of brain functions and neurodevelopmental disorders (Source).
