Explain What A Stroke Is And What Are The Types Of Stroke?
Answers
A stroke occurs when the supply of blood to the brain is either interrupted or reduced. When this happens, the brain does not get enough oxygen or nutrients, and brain cells start to die.
Ischemic Stroke (Clots) Occurs when a blood vessel supplying blood to the brain is obstructed. ...
Hemorrhagic Stroke (Bleeds) Occurs when a weakened blood vessel ruptures. ...
TIA (Transient Ischemic Attack) Called a “mini stroke,” it's caused by a serious temporary clot. ...

Answer:
The three main types of stroke are:
Ischemic stroke.
Hemorrhagic stroke.
Transient ischemic attack (a warning or “mini-stroke”).

Ischemic Stroke
Most strokes (87%) are ischemic strokes.1 An ischemic stroke happens when blood flow through the artery that supplies oxygen-rich blood to the brain becomes blocked.
Blood clots often cause the blockages that lead to ischemic strokes.
Hemorrhagic Stroke
A hemorrhagic stroke happens when an artery in the brain leaks blood or ruptures (breaks open). The leaked blood puts too much pressure on brain cells, which damages them.
High blood pressure and aneurysms—balloon-like bulges in an artery that can stretch and burst—are examples of conditions that can cause a hemorrhagic stroke.
There are two types of hemorrhagic strokes:
Intracerebral hemorrhage is the most common type of hemorrhagic stroke. It occurs when an artery in the brain bursts, flooding the surrounding tissue with blood.
Subarachnoid hemorrhage is a less common type of hemorrhagic stroke. It refers to bleeding in the area between the brain and the thin tissues that cover it.
