Stroke Caused by High Blood Pressure


Stroke is a leading cause of death and disability in adults. Based on research, the incidence of stroke in India is about 203 cases per 100,000 inhabitants above 20 years that amounts to about a total of 1 million cases. The most worldwide cause of stroke is high blood pressure. This makes hypertension or hypertension the one most important risk factor.

What’s Stroke?
A stroke could be defined as a sudden loss of brain functioning because of disturbance of the blood supply to the brain. It is caused by an acute vascular event such as interruption of blood supply (ischemic strokes) and/or bleeding into the brain tissue (hemorrhagic strokes). Interruption of the blood supply results in a deficiency of oxygen and other nutrients into the brain tissue. As the brain tissues use oxygen at an exceptionally large speed, interruption of their oxygen and other nutrients into the mind for a few seconds can cause considerable damage and serious complications.

Blood Supply to the Brain
Blood supply to the brain could be interrupted because of:

A block by a clot or other debris from the blood vessel, which supplies blood to the brain. Should this happen, you are having an ischemic stroke. This type of stroke is more common (85 % of strokes are of ischemic stroke)
A hemorrhagic stroke occurs when there is a rupture of the blood vessels within the brain, and this then leads to bleeding from the brain tissue and interruption of blood flow to tissues located after the stage of rupture
These two are potentially severe and can cause extensive damage and possibly serious complications.

The Impact of High Blood Pressure

The threat stroke due to elevated blood pressure is related to the level of blood pressure which is higher the blood pressure greater is the risk of stroke. The risk of stroke is significantly lower in patients using well-controlled blood pressure in comparison with patients with poorly controlled blood pressure.

Warning Signs of Stroke
The signs and symptoms of stroke depend on the region of the brain which is affected. But the symptoms that are a cause for concern include:

Loss of consciousness
Numbness or Weakness of any part of the body
Loss of sensation in any part of the body
Deviation of mouth to one side
Issue in talking
Issue in understanding dialog
Sudden visual defect in one or both eyes
Dizziness, giddiness, or unhappiness
Loss of equilibrium or unexplained falls
Stroke is an acute and possibly life-threatening illness so never ignore your symptoms. In a lot of individuals, the symptoms may last only for a few seconds. Ask your doctor or visit an emergency room immediately in the event that you have signs of stroke even if they persist only for a few seconds.
