Stroke - GCSE Psychology Definition

A stroke is a serious medical condition that happens when the blood supply to a part of the brain is cut off or reduced, stopping brain tissue from getting the oxygen and nutrients it needs. Without this blood flow, brain cells can begin to die within minutes. There are two main types of strokes: ischaemic, which is caused by a blockage like a blood clot, and haemorrhagic, which is caused by a blood vessel bursting and bleeding into the brain. Depending on which part of the brain is affected, a stroke can impact a person's memory, speech, movement, and behaviour. Since our brain plays a big role in controlling our thoughts, emotions, and actions, understanding strokes can help us learn more about how the brain influences our behaviour, something that is important in psychology.
