Can the brain repair itself after stroke? | Encompass Health
- Reduced swelling and improved circulation: In the initial stages after a stroke, the brain focuses on reducing swelling and improving blood flow to the affected area. This can help salvage some cells and create a better environment for healing.
- Sprouting new connections: Existing neurons near the damaged area can sprout new connections, or axons, to reach other healthy neurons. This helps reroute signals and restore lost functions.
- Reorganization of brain functions: The brain can also reassign functions to other healthy areas. For example, if the part of the brain responsible for speech is damaged, another area might take over that function.
Important factors to remember:
- Time is crucial: The brain’s ability to heal is highest in the weeks and months following a stroke. Early intervention with rehabilitation therapy is essential to stimulate neuroplasticity and maximize recovery.
- Limited repair: The brain cannot regenerate lost neurons, so complete recovery is often not possible. However, rehabilitation can help people regain a significant degree of function.
- Individual variability: The extent of recovery varies greatly depending on the severity and location of the stroke, as well as a person’s age and overall health.
