Researchers at Duke University have found an abnormality in visual regions of the brain being associated with an individual’s general risk for mental illness. The findings (link below) indicate a signature abnormality shared between common forms of mental illness, which could help clinicians assess a patient’s general risk for developing a mental illness. The signature abnormality was present in participants (605 university students) involved in the study who already had a higher risk of mental illness (participants met criteria for psychiatric disorders, including alcohol or substance use disorder, major depressive disorder, and bipolar disorder). This was characterized by a reduced efficiency between visual areas and brain networks important for integrating sensory information and suppressing distracting information.
