Helping people recover after stroke by boosting brain cell energy
Official title: Enhanced Mitochondrial Function Increases Effectiveness of Post-Stroke Rehabilitation
Funded at Southern Arizona VA Health Care System · NIH-11206889 · Data updated 2026-11-12
The team is seeing if a drug that clears harmful fat debris and restores cell energy can limit brain damage and improve movement recovery after stroke.

Who could benefit from this research
✓Could help
Ideal candidates for eventual human testing would be people who recently had an ischemic stroke and are undergoing motor rehabilitation for arm or leg weakness.
✕Less likely to help
People with non-ischemic (e.g., hemorrhagic) strokes or whose injury is many years old may be less likely to benefit from this specific approach.
What this research studies
If you had a stroke, this research is testing a medicine called HPβCD that helps immune cells clean up myelin-derived fat debris and restore their mitochondria (the cell's power plants). In mice, researchers give the drug after stroke and combine it with motor rehabilitation to see whether it reduces tissue loss and speeds recovery of movement and memory. They track brain tissue, inflammation, mitochondrial health in immune cells, and behavior to measure benefit. The work is currently done in an animal model at the Southern Arizona VA with the goal of informing future treatments for people who have had strokes.
Why it matters
Potential benefit: If successful, this approach could reduce long-term brain damage after stroke and make rehabilitative therapy more effective for regaining movement and memory.
How similar studies have gone: Preclinical studies in mice from the same group have shown promising results, but this specific treatment approach has not yet been tested in people.
