When blood stops flowing in your brain and damages your brain cells, you’ll experience a stroke. The flow stops because of a blood clot. The impact of a stroke depends on the area of the brain and the extent of the damage. Therefore, you can better understand stroke if you know how the brain operates. 

Types of Stroke

Aside from the part of the brain and the amount of damage, the effect of stroke also depends on its type. 

When there is a blood clot or blockage in your brain, this is an ischemic type of stroke. There is a possible build of plaque in the wall of an artery. A hemorrhagic stroke happens when a brain artery suddenly opens. The most common cause of this stroke type is high blood pressure. High blood pressure causes arteries to become weak. 

TIA or transient ischemic attack happens when an artery is blocked momentarily by a small clot. The symptoms often last not more than an hour. Since it happens for a few minutes only, it is also called a warning or mini-stroke. This is also an indication that a worse stroke may happen. 

A tumor, infection, swelling of the brain from a disease or injury are the other possible but rare causes of a stroke. People who have artery defects at birth can have a stroke later in their lives.

The effects of stroke in the body can be mild, moderate, or severe. How long the brain had no blood flow and the time it took for treatment to be given also play a role in the severity of a stroke.
