Identifying biomarkers for cognitive impairment after stroke using fNIRS

Identifying Biomarkers Related to Post-stroke Cognitive Impairment: A fNIRS Study

Observational First Affiliated Hospital of Chongqing Medical University · NCT06703307

This study is trying to find brain signals that can help us understand cognitive problems after a stroke by comparing stroke patients with healthy people while they do thinking tasks.

What this trial studies

This observational study aims to identify biomarkers associated with post-stroke cognitive impairment by utilizing functional near-infrared spectroscopy (fNIRS). It includes both healthy subjects and stroke patients, who will undergo cognitive tasks such as the Stroop task and verbal fluency tests while their brain activation is monitored. Various cognitive function assessments will be conducted to evaluate the participants' cognitive abilities and compare the results between the two groups. The goal is to uncover differences in brain activation and connectivity that may relate to cognitive decline following a stroke.

Who should consider this trial

Good fit: Ideal candidates include stroke patients aged 18-80 with a confirmed diagnosis and healthy individuals within the same age range who can complete cognitive tasks.

Not a fit: Patients with serious mental illnesses, significant organic diseases, or those unable to tolerate the tests may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and potential interventions for cognitive impairment in stroke patients.

How similar studies have performed: While this approach is innovative, similar studies using fNIRS for cognitive assessment in stroke patients have shown promise in identifying brain function changes.
