Stroke and Memory Loss: What’s the Connection?
A stroke occurs when blood flow to the brain is interrupted. This can happen due to a blood clot blocking an artery (ischemic stroke) or a burst blood vessel (hemorrhagic stroke). Strokes can cause a wide range of symptoms, including memory loss.
The severity of memory loss after a stroke depends on several factors, including the size and location of the stroke. Strokes that affect the parts of the brain responsible for memory, such as the hippocampus, are more likely to cause memory problems.
