The real cause of a common stroke may have been missed for decades

A groundbreaking discovery reveals that the primary cause of a frequent type of stroke might not be clogged arteries but rather enlarged and damaged blood vessels deep within the brain. This new insight challenges long-held beliefs and explains why traditional treatments have often fallen short. With this fresh understanding, researchers are now focusing on developing new therapies that specifically target these tiny, vulnerable brain vessels, potentially leading to more effective stroke prevention and treatment strategies.
