Hyper brain / hyper body: The trouble with high IQ
A study of 3,715 high-IQ individuals found increased prevalence of mood and anxiety disorders, ADHD, ASD, and immune-related conditions (allergies, asthma, autoimmune disease) compared with national averages. Authors propose a ‘hyper brain / hyper body’ theory linking heightened sensitivity and chronic stress to immune and behavioral dysregulation.
