Brain Stimulation on Higher-Order Cognition
open to eligible people ages 18-50
The purpose of this study is to better understand the neural correlates of higher-order cognition, both in the healthy brain and in schizophrenia, and to determine how these mechanisms are modulated by transcranial direct current stimulation (tDCS) at frontal and occipital scalp sites. Testing the effects of tDCS at these scalp sites on cognitive task performance will help us understand the roles of the brain regions corresponding to these sites during higher-order cognitive processing (language comprehension, cognitive control, and related attention and memory processes). Behavioral and electrophysiological (EEG) measures will be used to assess cognitive performance. The investigator's overarching hypothesis is that stimulating prefrontal circuits with tDCS can improve cognitive control performance, and ultimately performance on a range of cognitive tasks, as compared to stimulating a different cortical region (occipital cortex) or using sham stimulation. This study is solely intended as basic research in order to understand brain function in healthy individuals and individuals with schizophrenia. This study is not intended to diagnose, cure or treat schizophrenia or any other disease.

Dose-Optimized and Spaced Transcranial Direct Current Stimulation for Treatment-Resistant Depression
open to eligible people ages 18-85
This study aims to evaluate the feasibility, safety, and tolerability of an innovative approach to treating Major Depressive Disorder (MDD), particularly in cases where patients have not responded well to traditional therapies. Specifically, the objective is to evaluate the antidepressant effects of a Dose-Optimized and Spaced Transcranial Direct Current Stimulation (DOS-tDCS) protocol in participants with treatment-resistant depression (TRD) compared to spaced tDCS only and sham tDCS in a 3-arm randomized controlled trial (RCT). The proposed method involves applying low-intensity electrical currents through the scalp in a manner that is both more intense and more frequently spaced than standard treatments. This approach is hypothesized to lead to a significant reduction in depressive symptoms. Participants in the study will be randomly assigned to one of three groups: the experimental group receiving the DOS-tDCS treatment, a group receiving spaced tDCS only, or a control group receiving a sham (placebo) treatment. Outcomes will be measured over a period of six weeks. The study's goal is to offer a potentially more accessible and effective treatment option for individuals who have not benefited from existing MDD therapies.

Brain Stimulation on Cognition, Oscillations and GABA Levels in Schizophrenia
“Volunteer for paid research and contribute to discoveries that may improve health care for you, your family, and your community!”
open to eligible people ages 18-47
People with schizophrenia often have problems with attention, learning and memory and other cognitive abilities that interfere with their work and school performance. Unfortunately, even our best treatments often do not significantly reduce these cognitive problems. The current study investigates whether or not delivering a very small electrical current to people's foreheads (called, transcranial direct current stimulation; (tDCS)) might improve functioning in the front part of the brain and reduce these cognitive problems in people with schizophrenia. tDCS is non-invasive and has been shown to improve cognitive functioning in some preliminary studies. The current study will investigate whether giving tDCS during a task is more effective than giving it during rest (Aim 1), whether delivery of tDCS to the front of the head is more effective than delivery to the back of the head (Aim 2), and whether tDCS delivery will alter levels of a major inhibitory neurotransmitter in the brain (GABA; Aim 3) that is important to cognitive functioning and may be disrupted in people with schizophrenia. Although this study is not intended to diagnose, cure or treat schizophrenia or any other disease, if results are positive it will encourage future large-scale studies to determine if tDCS can become an effective treatment for cognitive problems in people with schizophrenia.

Speech-Language Treatment with Remotely Supervised Transcranial Direct Current Stimulation in Primary Progressive Aphasia
Sorry, in progress, not accepting new patients
Primary progressive aphasia (PPA) is a disorder characterized by gradual decline in speech-language ability caused by underlying neurodegenerative disease. PPA is a devastating condition that can affect adults as young as their 50's, depriving them of the ability to communicate and function in society. Along with Alzheimer's Disease and other Alzheimer's Disease Related Dementias (AD/ADRD), PPA is now identified earlier and with greater precision. Increasingly, patients and families seek options for behavioral and neuromodulatory treatments to address PPA's devastating effects on communication, prolong speech-language skills, and maximize quality of life. Studies have documented the robust benefits of speech-language telerehabilitation methods for persons with PPA, with in-home treatment resulting in immediate and long-term benefits. This investigation aims to further enhance the potency of these treatment approaches by pairing them with tailored neuromodulatory intervention that targets critical brain networks supporting treatment in each clinical subtype of PPA. The study will evaluate the feasibility and preliminary benefit of home-based transcranial direct current stimulation (tDCS) combined with evidence-based speech-language telerehabilitation methods. tDCS will be delivered to patients in their own homes and site of stimulation will be tailored for each clinical subtype of PPA. This project has the potential to enhance clinical management and rehabilitation for individuals with PPA by establishing the benefit of behavioral and neuromodulatory treatment that is neurobiologically-motivated and accessible for patients and families.

Transcranial Direct Current Stimulation for Treatment of Acute Ischemic Stroke
Sorry, not yet accepting patients
Many patients with acute ischemic stroke are ineligible for currently available standard treatments (clot-busting medication, also known as intravenous thrombolytic or mechanical removal of a clot), and many are non-responders, resulting in a low rate of excellent outcomes, which necessitates the development of novel therapies. In this study, investigators are testing a new treatment in which a weak electrical current will be applied via scalp electrodes to increase collateral blood flow to the brain and rescue the brain tissue at risk of injury. The primary aim is to find an optimal dose of this therapy that is both adequately safe and effective on imaging markers of brain tissue rescue.
