Home About Stroke. About Stroke Stroke is the No. What are the types of stroke? Ischaemic strokes are the most common type of stroke. They happen when a blood clot blocks the flow of blood and oxygen to the brain. These blood clots typically form in areas where the arteries have been narrowed or blocked over time by fatty deposits known as plaques.
This process is known as atherosclerosis. Your arteries may naturally become narrower as you age, but there are some things that dangerously speed up this process. Another possible cause of ischaemic stroke is a type of irregular heartbeat called atrial fibrillation.
This can cause blood clots in the heart that break apart and end up in the blood vessels that supply the brain. Haemorrhagic strokes also known as cerebral haemorrhages or intracranial haemorrhages are less common than ischaemic strokes. These drugs prevent the production of an enzyme that can turn cholesterol into plaque — the thick, sticky substance that can build up on the walls of arteries and cause strokes and heart attacks.
High blood pressure can cause pieces of plaque buildup in your arteries to break off. These pieces can block arteries, causing a stroke. As a result, managing high blood pressure with medication, lifestyle changes, or both can help prevent a stroke.
