What this trial studies

This study evaluates the effects of transcranial direct current stimulation (tDCS) on brain functioning and memory in individuals with post-stroke cognitive impairment (PSCI). It aims to understand how electrical stimulation influences brain activity, cerebral blood flow, and neuroinflammation biomarkers. The study employs non-invasive brain imaging techniques, including functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG), alongside cognitive assessments and blood sample analysis. Participants will undergo various tests to determine the impact of stimulation on their cognitive abilities.

Who should consider this trial

Good fit: Ideal candidates are individuals who have experienced an ischemic stroke within the sub-acute phase and exhibit cognitive dysfunction.

Not a fit: Patients with severe psychiatric conditions, significant neurological disorders, or contraindications to tDCS may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance cognitive functioning and memory in patients recovering from stroke.

How similar studies have performed: Other studies using non-invasive brain stimulation techniques have shown promise in improving cognitive functions, suggesting potential success for this approach.
