Stroke occurs when there’s a blockage in the blood supply to the brain it happens when a blood vessel in the brain ruptures and bleeds. Furthermore, oxygen supply to the brain ceases leading to brain damage.
Types of Strokes
There are three types of strokes with sub-types Ischemic Stroke Transient Ischemic Attack Hemorrhagic Stroke
Due to arteries being blocked or narrowed, ischemic stroke can also occur when too much plaque clogs blood vessel.
Ischemic stroke 1.Thrombotic- when a blood clot forms in one of the arteries supplying blood to the brain. 2. Embolic- when a blood clot or other debris forms in another part of the body go towards the brain.
Transient Ischemic Attack Is a temporary blockage period of symptoms similar to those you’d have in a stroke also know as mini stroke usually last 5 minutes.
Hemorrhagic stroke When there is bleeding in the brain -.Blood vessel in your brain balloons up and bursts or a weakened one leaks.
- Intracerebral hemorrhagic– when the tissues surrounding the brain fill with blood after an artery bursts.
- Subarachnoid hemorrhagic– when bleeding in the area between the brain and the tissues that cover it.
