Network-based tDCS for Apathy

Apathy is one of the most common and undertreated neurobehavioral symptoms in older adults with dementia. It is associated with reduced motivation and engagement in daily activities, and may contribute to faster cognitive and functional decline. Currently, there are no approved pharmacologic treatments for apathy, and many behavioral interventions are difficult for individuals with apathy to initiate and sustain. This ISAC-funded pilot study will examine the feasibility of a home-delivered, network-based transcranial direct current stimulation intervention designed to target and non-invasively stimulate brain regions involved in motivation and goal-directed behavior, including the dorsolateral prefrontal cortex and anterior cingulate cortex. The study will assess feasibility, safety, adherence of this intervention for older adults with dementia and apathy, and obtain preliminary data of clinical and neurophysiological measures. The team has submitted the IRB application, which is currently pending review, and has posted a position to hire a new research assistant who will support recruitment, study coordination, and intervention delivery. These start-up activities will help prepare the team to launch participant enrollment once regulatory approvals and staffing are in place.

The Effect of Non-invasive Brain Stimulation rTMS on Hand Muscles in Chronic Stroke Patients.

The study is about using a brain stimulation technique called rTMS (Repetitive Transcranial Magnetic Stimulation) to help improve hand muscles in people who had a stroke. Researchers want to understand how this device can help stroke patients use their hands better.

Effects of Transcranial Electrical Stimulation on Task Performance in Healthy Adults

The objective of this randomized, double-blind, sham-controlled, crossover study is to evaluate the effects of transcranial electrical stimulation (tES) on complex cognitive task performance in healthy adult volunteers. The primary questions this study aims to answer are: 1. Does tES improve task performance, including speed, accuracy, and overall success, during a computerized track-and-capture task? 2. Do different stimulation targets produce differential effects on performance? 3. Are there short-term post-stimulation effects on task performance (up to 48 hours)? Participants will: 1. Complete two testing sessions under either active or sham stimulation conditions. 2. Perform a complex operational task involving dual-hand controllers while undergoing tES or sham stimulation, and immediately after. 3. Return for follow-up task performance assessments at 24 and 48 hours post-stimulation to evaluate after-effects.

Cortical Excitability and Role of Non Invasive Brain Stimulation in ADHD and AUTISM

This double-blind, randomized, sham-controlled clinical trial will evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on children and adolescents with attention-deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD) and matched healthy controls. Participants aged 6-19 years will be assigned to active or sham rTMS protocols targeting the dorsolateral prefrontal cortex over 3 weeks, with assessment of changes in disorder-specific symptoms and cortical excitability. The study aims to determine the safety, feasibility, and preliminary efficacy of rTMS as a non-invasive neuromodulation approach in pediatric neurodevelopmental disorders.
