A new study suggests that a common type of stroke may not be caused primarily by fatty plaque buildup in the arteries, as long believed. Instead, researchers found a stronger connection with enlarged and damaged small blood vessels deep within the brain. This discovery could explain why standard treatments, such as aspirin, are often less effective for these patients. The findings also point toward a new treatment strategy focused on protecting and repairing the brain’s tiny blood vessels rather than simply preventing blood clots. While more research is needed, this breakthrough could pave the way for more targeted and effective stroke therapies in the future.
