Stroke is a leading cause of death and disability in adults. Based on studies, the incidence of stroke in India is about 203 cases per 100,000 population above 20 years which amounts to approximately a total of 1 million cases. This makes high blood pressure or hypertension the one most important risk factor.
What is Stroke?
A stroke can be described as a sudden loss of brain function because of interruption of the blood supply to the brain. Interruption of the blood supply results in a deficiency of oxygen and other nutrients into the brain tissue. Since the brain tissues utilize oxygen at an exceptionally high speed, disturbance of their oxygen and other nutrients into the mind even for a few seconds can cause extensive damage and severe complications.
Blood Supply to the Brain
Blood supply to the brain can be interrupted due to:
A block by means of a clot or other debris in the blood vessel, which supplies blood to the brain. Should this happen, you’re having an ischemic stroke. This Sort 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 in the brain, and this then leads to bleeding from the brain tissue and disruption of blood supply to cells located after the stage of rupture
These two are potentially serious and can cause extensive damage and potentially serious complications.
The Impact of High Blood Pressure
The threat stroke due to high blood pressure is directly associated with the level of blood pressure which is greater the blood pressure higher is the risk of stroke. The risk of stroke is lesser in patients with well-controlled blood pressure as compared to 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. However, the symptoms that are a cause for concern include:
Reduction of consciousness
Numbness or Weakness of any part of the body
Loss of feeling in any part of the body
