Cerebrovascular Disease

Cerebrovascular Disease involves a wide range of condition. Such as stroke, carotid stenosis, vertebral stenosis and intracranial stenosis, aneurysms and vascular malformations are included.

They affect the flow of blood through the brain. This change is sometimes temporarily or permanently affected by ischemia or bleeding, which can impair brain functions. Such a sudden event is known as a Cerebrovascular (CVA).

The term Cerebrovascular is made up of two parts, the first is “cerebro” which refers to a large part of the brain and the second is “vascular” which means arteries and veins.

Together, the term, cerebrovascular refers to the flow of blood to the brain.

Cause

cerebrovascular disease can develop due to various reasons:-

  1. Due To Damage To A Blood Vessel In The Brain :- When a blood vessel is damage in the brain, it does not reach enough blood in the area of the brain. And this lack of blood hinders the delivery of sufficient oxygen, and without oxygen, brain cells stand during.
  1. Due To High Cholesterol :- Cerebrovascular disease occurs when high cholesterol levels, combined with inflammation in the arteries of the brain, block blood flow in the arteries in the form of thick, waxy plaque. This can restrict or completely obstruct blood flow to the brain, causing an attack of cerebrovascular, such as a stroke or TIA (Treansient Ischaemic Attack).

Types Of Cerebrovascular Disease

there are mainly two types of cerebrovascular disease.

  1. Ischemic stroke :- When a blood clot blocks a blood vessel and prevents blood and oxygen from entering a part of the brain, it is called ischemic stroke.

          This can happen in two ways.

1.1. First Embolic stroke :- When a clot is formed elsewhere un your body and accumulates in the blood vessel in the brain.

1.2. Second Thrombotic stroke :- When a clot forms in the blood vessel within the brain.

  1. Hemorrhagic Stroke :- Due to the rupture and bleeding of the blood vessel, the blood does not get into the part of the brain. This bleeding can occur in and blood vessel or surrounding membrane of the brain, which we call hemorrhagic stroke.

Symptoms

Symptoms of cerebrovascular include.

  1. Numbness of paralysis in one side of face, leg or arm.
  2. Difficulty in speaking or understanding.
  3. Trouble in balancing and co-ordinating something.
  4. Sudden headache when nausea, vomiting or dizziness.
  5. Difficulty in walking.
  6. Blurred vision.

Risk-Factor

this following risk-factors should be avoided which can cause cerebrovascular disease. (CVA)

  1. Hemoglobin level higher than normal.
  2. Heart failure or valvular heart disease.
  3. High blood pressure patient taking birth control pills.
  4. Age related morbidity.
  5. High cholesterol.
  6. Diabetes.
  7. Smoking and drinking habit.
  8. Obesity.
Prevention

For the prevention of cerebrovascular disease, a few think should be kept in mind.

  1. Stop or limit smoking and alcohol.
  2. Control high blood pressure and high blood cholesterol.
  3. Eat a healthy and balanced diet.
  4. Stay away from hormone replacement therapy.
  5. Reduce stress levels.
  6. Do regular exercise.
  7. Maintain a healthy weight.
  8. Get your doctor checkup regularly.
