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.

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.

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.

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).
