Recent surveys suggest that every 40 seconds someone is affected by a brain stroke & every 4 minutes someone dies from it. Brain stroke is crucial & common health nowadays. A brain stroke can happen to anyone at any time & may even reoccur in some cases. It has become one of the leading causes of death around the globe. Remarkably few people recover entirely from the brain strokes, while some disability strikes most of the survivors for a lifetime. The harm caused by & also the treatment of a brain stroke depends upon the part of the brain that is affected by the stroke. Besides all this, 80% of the brain strokes can be prevented, only if we have sufficient knowledge of the topic.

What is a brain stroke?

A brain stroke is necessarily disruption of blood flow to a specific part of the brain. This confuses oxygen to the brain thus damaging the brain cells & ultimately causing them to die. Due to this, the functions of that part of the brain are disturbed & might stop altogether. A brain stroke might be of little frequency or even significant. Small brain strokes might cause temporary inability to move a muscle while large brain strokes may also cause permanent paralysis of half or yet complete body. Whether the brain stroke is large or small, it is necessary to seek medical help in both the cases as soon as possible.

What causes a stroke in the brain?

The primary cause of a brain stroke is the break in supply of the blood to the brain. This deprives the brain of oxygen & other essential nutrients due to which it ceases to function. The brain cells start dying thus causing non-functioning of a particular part of the brain. Brain strokes are differentiated into various types, depending upon their causes as given below.

Ischemic Stroke:

Ischemic brain strokes are caused when the arteries carrying blood to your brain are either narrowed or blocked due to mostly a clot or thrombus, reducing blood supply to the brain. It is the most common type of brain strokes & occurs in 85 of the people reporting brain strokes. Common types of Ischemic brain strokes are Thrombotic Strokes & Embolic Strokes.

Haemorrhagic Strokes:

Haemorrhagic brain strokes are caused by either a leaking or a ruptured brain artery. Bursting or leaking of a brain artery may be caused by some health conditions like high blood pressure, overuse of anticoagulants or weak spots in arterial walls. Another rare cause of haemorrhagic brain stroke is bursting or rupturing of an abnormal tangle of thin-walled artery present at birth. Common types of Haemorrhagic brain strokes are intracerebral haemorrhage & subarachnoid haemorrhage.
