STROKE

Stroke is the sudden death of neurons in localized brain areas due to inadequate blood supply to that area.

A stroke occurs when a blood vessel in the brain ruptures and bleeds, or when there’s a blockage in the blood supply to the brain. The rupture or blockage prevents blood and oxygen from reaching the brain’s tissues. Without oxygen, brain cells and tissue become damaged and begin to die within minutes. 

It can be characterized with reversible and irreversible paralysis and other symptoms.

It is also called CEREBROVASCULAR ACCIDENT OR BRAIN ATTACK

CAUSES

1. Heart diseases

2. Hypertension

3. High cholesterol in blood

4. High blood sugar

5. Heavy smoking 

6. Heavy alcohol consumption

TYPES

ISCHEAMIC STROKE

IsCheamic stroke occurs due to interruption of blood supply or flow to a part of the brain by thrombus or atherosclerotic embolus.

HEMORRHAGIC STROKE

Tho stroke is developed due to the rupture of a blood vessel in the brain, there by stopping the flow of blood to a particular area.

SYMPTOMS

1. Dizziness

2. Loss of consciousness

3. Coma or death

4. Weakness 

5. Numbness or paralysis, particularly on one side of the body

6. Impairment of speech

7.loss of memory

8.loss of coordination

9.Emotional disturbance

The loss of blood flow to the brain damages tissues within the brain. Symptoms of a stroke show up in the body parts controlled by the damaged areas of the brain.

The sooner a person having a stroke gets care, the better their outcome is likely to be. For this reason, it’s helpful to know the signs of a stroke so you can act quickly.
