About

Dr. Paul E. Croarkin is a leading child and adolescent psychiatrist whose research focuses on the neurobiology and treatment of pediatric neuropsychiatric disorders, particularly through the application of noninvasive brain stimulation techniques. His major contributions center on exploring the therapeutic potential of repetitive transcranial magnetic stimulation (rTMS) in children, with a specific emphasis on Tourette syndrome. In a pivotal 2021 study, Dr. Croarkin investigated the feasibility and effects of low-frequency rTMS delivered to the supplementary motor area (SMA) on tic severity and motor system neurophysiology in children with Tourette syndrome. This work, which has garnered over 50 citations, represents a critical step in understanding how brain stimulation can modulate motor circuits in developmental disorders. Beyond this, his broader research portfolio includes pioneering studies on rTMS for adolescent depression and anxiety, as well as investigations into biomarkers of treatment response. Dr. Croarkin’s work is notable for its translational impact, bridging mechanistic neuroscience with clinical applications to improve outcomes for young patients. His contributions have established him as a key figure in pediatric neuromodulation, earning him recognition through numerous grants and leadership roles in the field.
