Neurology

The medical condition of stroke characterises poor or loss of blood flow to the human brain, which results in the death of cells. The two major forms of stroke include ischemic stroke (or lack of flow of blood to the brain) and haemorrhagic stroke (occurs due to bleeding). Ischemic Stroke This is the most common stroke condition in humans and is caused due to the formation of a blood clot that does not allow the blood to flow through the vessels and reach the brain. The clot may plug or block the blood vessel and the brain cells start to die within minutes of the blocking. As the artery carries fresh and oxygenated blood to the brain cell, the cells die due to lack of oxygen, and the accumulation of cellular waste and carbon dioxide also occurs in the affected areas of the brain. The two common types of Ischemic Stroke include: Thrombotic Stroke This stroke occurs due to the clotting of blood and formation of the blood clot within the brain area. This form of stroke acc
