Understanding fatigue after a first ischemic stroke

Better Understanding of Fatigue After STroke

NA · Brugmann University Hospital · NCT06292377

This project will try to see if measures of heart rhythm, blood tests, and brain scans can explain why adults who recently had a first ischemic stroke develop ongoing fatigue.

What this trial studies

Adults with a first-ever ischemic stroke who are admitted within 72 hours to two Brussels stroke units will be enrolled and undergo ECG (for heart rate variability), transthoracic echocardiography, blood sampling, brain MRI, and standardized questionnaires for fatigue, cognition, mood, and sleep. The study will compare early (<3 months) and late (>3 months) post-stroke fatigue and relate symptom patterns to markers of autonomic dysfunction. Researchers will analyze whether altered heart rate variability and other biological markers correlate with persistent fatigue after stroke. No experimental drug or device is being tested; the focus is on physiological and clinical measurements to clarify underlying mechanisms.

Who should consider this trial

Good fit: Adults (≥18) admitted to CHU Brugmann or UZ Brussel with a first-ever ischemic stroke within 72 hours who can undergo MRI and complete fatigue, cognitive, mood, and sleep assessments in French or Dutch.

Not a fit: People with prior strokes or other structural brain lesions, severe language impairment or dementia, life expectancy under one year, pregnancy, or who cannot speak French or Dutch are unlikely to benefit from this project.

Why it matters

Potential benefit: If successful, the findings could help identify patients at higher risk of post-stroke fatigue and point to new ways to prevent or treat it.

How similar studies have performed: Previous observational work has linked autonomic dysfunction and altered heart rate variability to worse post-stroke outcomes, but interventions to prevent or treat post-stroke fatigue based on these findings remain unproven, so the approach is exploratory.
