Stroke; is caused by the interruption of the blood supply to the brain, usually because a blood vessel is block by clothing. cutting off the supply of oxygen nutrients causing damage to the brain tissues.

Signs and symptoms of stroke;

The most common symptom is sudden weakness of the face, arm or legs and most often one side of the body;

  • Difficulty seeing with one or both eyes
  • Difficulty in walking, dizziness, loss of balance.
  • difficulty in speaking or understanding
  • Numbness of face, leg, arm especially one side the body.
  • unconsciousness or fainting
  • Headache with no cause.

Types of stroke;

  • Ischemic stroke; These are strokes brought on by an artery (or, in some cases, a vein) obstruction. An estimated 87% of stroke cases are ischemic.
  • Hemorrhagic stroke;These are strokes caused by bleeding. About 13% of strokes are hemorrhagic.
  • Thrombotic stroke; blood clot, that forms in the arteries delivering blood to the brain is the cause of thrombotic strokes. This kind of stroke typically affects the elderly, particularly those with diabetes, high cholesterol, and atherosclerosis—a buildup of fat and lipids inside blood vessel walls. Thrombotic stroke symptoms can sometimes strike unexpectedly, usually in the middle of the night or early in the morning. In other situations, it could happen gradually over several hours or even days.
  • Embolic strokes: An embolus, or blood clot, that originates elsewhere in the body and makes its way to the brain through the circulation is often the source of embolic strokes. Heart surgery or heart illness are common causes of embolic strokes, which happen quickly and without any warning symptoms. People with atrial fibrillation, a kind of irregular cardiac rhythm in which the heart’s upper chambers beat ineffectively, account for around 15% of embolic stroke cases.
  • Haemorrhagic Stroke; occur when a blood vessel that supplies the brain ruptures and bleeds. When an artery bleeds into the brain, brain cells and surrounding tissues and irritation and swelling occur, which can lead to further tissues do not get oxygen and nutrients. In addition, pressure builds up in brain damage.

Major Risk factors for stroke;

  • High blood pressure
  • Diabetes.
  • Heart diseases
  • Smoking.
  • Age and gender
  • Race and ethnicity
  • Brain aneurysms or arteriovenous malformations (AVMs)
