The Link Between Sleep and Stroke Links by the Research in the Paper

The Link Between Sleep and Stroke Links by the in the University of Cambridge - Research Paper Example Haemorrhagic stroke is also known as cerebral haemorrhages or intracranial haemorrhages. These types of strokes are not as common as ischaemic strokes. Sudden bleeding in the brain causes a haemorrhagic stroke. This bleeding makes the brain to swell and increased pressure is build up in the skull thus busting. The swelling and pressure damage the tissues and the brain cells. High blood pressure is an example of a condition that causes a hemorrhagic stroke (Meschia 3-4). It weakens the arteries in the brain making them prone to rupture or split. There are things that increase the risk of high blood pressure which include smoking, obesity, an excessive amount of alcohol, lack of exercise and stress. Haemorrhagic strokes can as well occur as a result of rupture of a brain aneurysm and badly formed blood vessels in the brain (Connolly et al 1712). Stroke effects vary from one person to another depending on the type, location, severity and the number of strokes. There are both mental and physical effects of stroke. Weakness or paralysis is one effect that may affect one side of the whole body or just a leg or an arm. This leads to problems of balancing and coordinating because the weight of the weak side pulls against the strong side. The other effect is a problem when using a language where a person may have problem understanding writing or a speech, have the problem of thinking the right words to speak or write or have a problem of saying words clearly. Again, a person with a stroke may suffer vision and perception problems. The condition also causes cognitive problems which include problems with thinking, attention, memory, mental activities and learning (Go 28-30).
