Summary

This prospective observational study aims to investigate cerebrospinal fluid mitochondrial biomarkers in patients with ischemic stroke and Alzheimer disease controls who undergo diagnostic lumbar puncture for clinical indications at Xuanwu Hospital, Capital Medical University.

Residual cerebrospinal fluid samples will be analyzed by flow cytometry to quantify mitochondrial content, mitochondrial membrane potential, and cellular or vesicular source-related markers. The flow cytometry panel will include MitoTracker, JC-1, and membrane-associated markers including CD45, CD41, CD24, vWF, and EAAT1.

In patients with ischemic stroke, the study will further examine whether cerebrospinal fluid mitochondrial measurements are associated with neurological severity and functional outcomes, including admission and discharge NIHSS scores and the 90-day modified Rankin Scale score. Alzheimer disease patients undergoing diagnostic lumbar puncture will serve as disease controls for biomarker comparison.

Cerebrospinal Fluid Flow Cytometry

Residual cerebrospinal fluid obtained during clinically indicated diagnostic lumbar puncture will be analyzed by flow cytometry. The assay will measure mitochondrial signal using MitoTracker, mitochondrial membrane potential using JC-1, and membrane-associated markers including CD45, CD41, CD24, vWF, and EAAT1. The study does not assign participants to any treatment or diagnostic procedure beyond routine clinical care.
