Causes
Stroke exists as a consequence of blood supply to part of an individual’s brain as it is interrupted or reduced due to a blocked artery or leaking/bursting of a blood vessel. In simpler words, a stroke occurs due to 2 main causes. Either an article blocks the flow of blood or something causes bleeding in the brain. The particular cause of stroke depends on the type of stroke
Ischemic stroke:
For example the cause of an ischemic stroke is a plugged/disrupted blood vessel which leads to the brain. This occurs due to fatty deposits present in one’s arteries which break off and travel to the brain. The blocked blood flow is caused by a blood clot or by atherosclerosis (diseases which causes narrowing of arteries).
Hemorrhagic stroke:
The cause of a hemorrhagic stroke is a weakened vessel which ruptures and bleeds into the surrounding brain. This blood then accumulates and compresses the surrounding brain tissue.
TIA (transient ischemic attack):
Lastly, the cause of a TIA (transient ischemic attack) is a buildup of fatty deposits (contains cholesterol) called plaques (atherosclerosis) in an artery or one of its branches which supply oxygen and nutrients to the brain.
