ischemic penumbra

Ischemic penumbra refers to the area of the brain that is at risk during a stroke. When blood flow is blocked, the tissue in the penumbra is damaged but still alive; it's not dead like the center of the stroke, where blood supply is completely cut off. This area can potentially recover if blood flow is restored quickly. Timely medical intervention can save this tissue, minimizing long-term damage and improving recovery outcomes for stroke patients. Understanding this concept highlights the importance of prompt treatment during a stroke.
