Although multiple treatments for OCD exist, slow symptom decrease, high remission, and significant side effects for some OCD patients limit their efficacy. More research into the precise neural mechanisms and linked cognitive functions in OCD is also necessary. To address both concerns, this study by Dr. Reinhart and his team will test a new, non-invasive, and well-tolerated neuromodulation method for reducing OCD symptoms, based on reward-related rhythms of the orbitofrontal cortex (OFC; a brain region responsible for reward, decision making and other crucial functions that is affected by OCD). This proposal is based on highly encouraging preliminary data in both subsyndromal and treatment-resistant populations that shows rapid reductions in OCD behaviors that last at least 1-3 months. Using high-definition transcranial alternating current stimulation (HD-tACS) guided by EEG brain wave recordings, the study will test whether repetitive modulation of relevant rhythm activity in the OFC can lead to rapid (within five days) and sustainable (up to three months) OCD symptom reduction. This research aims to increase knowledge of OCD and development of effective treatment with minimal side effects.

Clinically characterized as executive dysfunction, these deficits are associated wit1 expand

Deficits in cognitive control are core features of late-life depression (LLD), contributing both to emotion dysregulation and problems with inhibiting irrelevant information, conflict detection, and working memory. Clinically characterized as executive dysfunction, these deficits are associated with poor response to antidepressants and higher levels of disability. Improvement of cognitive control network (CCN) dysfunction may benefit both mood and cognitive performance, however no current pharmacotherapy improves Cognitive Control Network deficits in LLD. The study examines the hypothesis that nicotine acetylcholine receptor agonists enhance Cognitive Control Network function. This effect may resultantly improve mood and cognitive performance in LLD. Small, open-label studies of transdermal nicotine (TDN) patches have supported potential clinical benefit and provided support that transdermal nicotine administration engages the Cognitive Control Network. This blinded study will expand past open-label trials supporting potential benefit in LLD. It will examine TDN's effect on depression severity and cognitive control functions measured by neuropsychological testing. The study will evaluate 60 eligible and enrolled participants over a 3-year period.

The overall objective of this in-lab randomized controlled trial is to test the efficacy of multi-day interruptions in sedentary behavior vs. single bouts of sustained exercise on metabolic, cognitive, affective, and cardiac autonomic nervous system responses in children with overweight and obesity who are at risk for type 2 diabetes. The use of continuous glucose monitoring will provide insight into the daily and cumulative metabolic effects of each condition that have thus far not been studied. In-lab studies demonstrating sustained efficacy of this approach in ameliorating negative effects of sedentary behaviors in children are necessary for the optimization of field-based interventions. Given the lack of success of interventions to prevent obesity-related diseases and increasing rates of type 2 diabetes in children and its related healthcare costs, this study addresses a critical public health need by testing of novel intervention strategies to reduce obesity-related diseases in children with overweight and obesity.
