Stroke occurs when there is a disruption or reduction of blood supply to the brain, causing the brain to be deprived of oxygen and nutrients. Brain cells, depending on the severity of the disruption, may suffer transient disturbance of function or even permanent death. Strokes can be differentiated into two main types – ischemic and hemorrhagic. There is also another sub-set of stroke called the Transient Ischemic Attack (TIA). 






What is Transient Ischemic Attack (TIA)?


Transient Ischemic Attack (TIA) or often termed ministroke, happens when there is a clot blocking blood flow to part of the brain briefly. The stroke symptoms caused by TIA last less than 24 hours.

•    Headache
