A Stroke is an attack on the brain. It is caused when not enough blood is supplied to the brain.

Brain cell function requires a constant delivery of oxygen and glucose from the bloodstream. The disruption in the blood supply to the brain can be due to either ischaemia (lack of blood flow) caused by a blockage or a haemorrhage in the brain (leakage of blood). Strokes can therefore be classified into 2 major categories: ischaemic and haemorrhagic.

As a result of the Stroke, the affected area of the brain has difficulty functioning, which might result in problems, including the inability to move one or more limbs on one side of the body; inability to understand or formulate speech; impaired memory and/or an inability to see one side of the visual field.

A Stroke on the left side of the brain affects the right side of the body and vice versa.

A mini stroke (TIA)- Transient Ischemic Attack
Symptoms are sudden but disappear within 24 hours leaving no permanent damage. This should be treated as a warning as it can be an opportunity to prevent a Stroke in the future.
