Study links OCD improvement to brain activity shift

A recent study from Baylor College of Medicine and Texas Children's Hospital has identified a specific neural activity pattern as a novel biomarker to accurately predict and monitor the clinical status of individuals with obsessive-compulsive disorder (OCD) who have undergone deep brain stimulation (DBS), a rapidly emerging therapeutic approach for severe psychiatric disorders. The study, led by led by Drs. Sameer Sheth and Wayne Goodman along with co-lead authors, Drs. Nicole Provenza, Sandy Reddy, and Anthony Allam, was published in Nature Medicine.
