STROKES: A NEW CAUSE DISCOVERED For decades, doctors have believed that a common type of stroke was caused by fatty plaque clogging up arteries. But new research from the University of Edinburgh flips that idea on its head. It turns out the real culprit might be something much deeper — tiny blood vessels in the brain that are damaged and enlarged. This discovery could explain why standard treatments, like aspirin, often fall short for this type of stroke. Instead of battling clogged arteries, scientists now think the key lies in directly protecting these fragile little vessels. The type of stroke in question is called lacunar ischemic stroke . It happens when the brain’s smallest blood vessels get damaged through a condition known as small vessel disease. This stroke isn’t just a one-off event — it’s a major cause of long-term disability and is linked to memory loss, dementia, and a higher chance of future strokes. A team led by researchers from Edinburgh, together with internati...
