Can a blocked carotid cause memory problems?

Yes, a blocked carotid artery can lead to memory problems. The carotid arteries supply blood to the brain, and if they become narrowed or blocked, it can reduce blood flow, potentially resulting in cognitive issues, including memory loss. This condition may also increase the risk of transient ischemic attacks (TIAs) or strokes, which can further impact cognitive function. It's essential to seek medical evaluation if experiencing memory problems, especially in the context of vascular issues.
