Rajiv Ratan, MD, PhD, of the Burke Neurological Institute, explains the mechanisms involved in how cells undergo ‘programmed death’ following a hemorrhagic stroke.

A hemorrhagic stroke occurs when a blood vessel bursts and blood leaks into the surrounding brain tissue. This type of stroke is relatively rare, and it is only recently that studies have begun to better understand how hemorrhagic strokes impact the brain.

Studies in Dr. Ratan’s lab indicate that the breakdown of blood cells following a stroke can trigger the destruction of other cells and efforts are underway to develop treatments aimed at preventing that ‘programmed cell death’ following a hemorrhagic stroke.
