A Study to Assess Change in Disease Activity and Adverse Events (AEs) With Cariprazine in the Treatment of Depressive Episodes in Pediatric Participants Participants (10 to 17 Years of Age) With Bipolar I Disorder.
Recruiting
Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population and 1.8% of the pediatric population in the United States. The treatment of the depressive episodes of bipolar disorder in the pediatric population has not been as widely studied as the treatment of depressive episodes in bipolar disorder in adults, therefore pharmacotherapeutic options are limited. Given the change in disease state and safety demonstrated in adults with depressive episodes associate... Read More

Dual Frequency Stimulation in Parkinson's Disease
Recruiting
Deep brain stimulation (DBS) in the dorsal region of the subthalamic nucleus (STN) is very effective for reducing motor symptoms of Parkinson's disease (PD). Modeling studies suggest that this therapy may result in current spread into the ventral STN, causing altered cognitive processes. As a result, current stimulation parameters often lead to worsening in verbal fluency, executive function, and, particularly, cognitive control. There is evidence suggesting that low frequency oscillatory activi... Read More

Meditation Accelerated Brain Stimulation for Depression
Recruiting
Repetitive Transcranial magnetic stimulation (rTMS) is an FDA-approved treatment for depression that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. The ultimate goal of this treatment is to increase excitability and long-term plasticity in DLPFC, a brain region shown to be hypo-active in depression. Unfortunately, rTMS only has low to moderate efficacy; remission rates for patients range from \~15-30% in large randomized controlled trials.... Read More
