One in every 40 Americans struggles with obsessive-compulsive disorder (OCD), which occurs when obsessive thoughts lead to repetitive behaviors that can hinder a person’s day-to-day activities. But UCLA researchers believe that brain scans could help determine which OCD patients would benefit most from cognitive behavioral therapy—or placing patients in controlled environments where they can learn how to tolerate anxiety-inducing stimuli. Certain brain scan patterns may provide clues to determine the best course of therapy before launching into costly and time-consuming treatment. However, a brain scan could save them thousands of dollars in the long run compared to trying, what may otherwise be, unsuccessful treatment. Could this news affect you or someone you know?
