In this episode, Dr. Jeffrey Strawn addresses your unanswered questions from his presentation: Re-Counting Neurobiological Treatment Advances of Obsessive-Compulsive Disorder.    Dr. Jeffrey R. Strawn's early work examined the neurophysiology, neurochemistry and neuroanatomy of anxiety disorders in children and adolescents.In parallel with Dr. Strawn's work on the neurophysiology of mood and anxiety disorders in children and adolescents, he has worked to increase the evidence base for treatment interventions in youth. Using meta-analysis, he demonstrated that antidepressants are well-tolerated in pediatric patients with anxiety disorders, but also examined specific class-specific side effects (e.g., activation). Also, he has examined the unique tolerability of antidepressants in special populations of adolescents with depressive and anxiety disorders (e.g., those who are at high risk for the development of bipolar disorder) and has observed that antidepressants are poorly tolerated in this population with likelihood of antidepressant adverse events leading to discontinuation being directly related to age. Additionally, he has extensive expertise in the conduct of double blind, placebo-controlled trials in youth with anxiety disorders.
