There are two types of stroke – ischemic and hemorrhagic.
Ischemic strokes are relatively common and are caused by a blood clot or narrowing of a blood vessel , that becomes blocked and thus prevents blood flow to the brain.
Hemorrhagic stroke is less common and occurs when a blood vessel in the brain bursts and causes internal bleeding in it.
What happens in the body during a stroke
Nowadays stroke is the 5th most common cause of death. It is also among the major factors causing partial or total disability.
Even if a person survives a stroke, they usually remain affected by paralysis of one half of the body.
In both cases, ischemic and hemorrhagic strokes, oxygenated blood cannot reach the nerve cells in the brain. These then die, which leads to the impairment of functions for which that part of the brain was responsible.
The brain is a very complex organ. When regions that control specific bodily functions become disabled, that part of the body will never function the same as before.
Partial recovery of functions through rehabilitation is possible, but the original condition is usually never fully restored.
Early signs of a stroke
There is a belief that a stroke appears suddenly and cannot be predicted in advance. This is not entirely the case.
Our body usually sends us the following signals before an impending stroke:
- frequent hiccups
- fainting
- physical weakness
- pain in various parts of the body
- breathing problems
- hallucinations
- epileptic seizures
- changes in behavior
It is very important to correctly recognize the above signals and seek medical help as soon as possible to minimize the risk of serious brain .
Such help can reduce the risk of death and disability and significantly increase the chances of faster recovery.
Doctors and medical experts say that symptoms can vary among individuals depending on the type of stroke, the affected part of the brain, and the extent of the damage.
However, their common feature is that a stroke usually comes on suddenly. Therefore, one should be prepared in advance for this moment.
