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.
What are the symptoms of stroke?
• Drooping, weakness or numbness of the face, arm or leg
• Difficulty with seeing in one or both eyes
• Difficulty with speaking and understanding
• Difficulty with walking
What are the treatments for stroke?
The emergency treatment for stroke will depend if it is an ischemic stroke or a hemorrhagic stroke. When the patient is medically stable, the next focus of treatment will be on rehabilitation.
