tDCS for Post-Stroke Cognitive Impairment

University of Oklahoma

Start Date

Completion Date

Summary

This study will evaluate the effects of a form of non-invasive brain stimulation on brain functioning and memory in participants with post-stroke cognitive impairment (PSCI).

Detailed Description

The goal of this study is to learn important information about the effects of electrical stimulation (Transcranial direct current stimulation (tDCS) on brain functioning in those with post-stroke cognitive impairment (PSCI). The findings will help determine how stimulation affects the brain's activity, cerebral blood flow, and circulating blood biomarkers of neuroinflammation after stroke. The study will use different forms of non-invasive brain imaging to see whether stimulation changes how the brain responds during a memory task. Functional near-infrared spectroscopy (fNIRS) and electroencephalograph (EEG) will be used, we will also collect blood samples for the biomarkers of inflammation. The study also uses cognitive tests and questionnaires.

Eligibility Criteria

Age Range: 18 years to 99 years

Inclusion Criteria: 1\) ischemic stroke participants in sub-acute phase (at least 10 days after stroke event or discharge and under 5 months post-event) with cognitive dysfunction (MoCA \<26); Exclusion Criteria: 1. clinically significant or unstable medical or psychiatric condition; 2. diagnosis of severe depression; 3. history of relevant neurological diagnosis (e.g., epilepsy); 4. previous neurosurgical procedure with craniectomy; 5. contraindications to tDCS (implanted brain medical devices); 6. severe visual impairment, hearing impairment, aphasia, neglect or dementia.
