STROKE

What is a stroke?

A stroke is a sudden loss of brain function. It is caused by the interruption of flow of blood to the brain (ischemic stroke) or the rupture of blood vessels in the brain (hemorrhagic stroke). The interruption of blood flow or the rupture of blood vessels causes brain cells (neurons) in the affected area to die. The effects of a stroke depend on where the brain was injured, as well as how much damage occurred. A stroke can impact any number of areas including your ability to move, see, remember, speak, reason and read and write.

In a small number of cases, stroke-like damage to the brain can occur when the heart stops (cardiac arrest). The longer the brain goes without the oxygen and nutrients supplied by the blood flow, the greater the risk of permanent brain damage. Brain injuries can also result in uncontrolled bleeding and permanent brain damage. This is usually referred to as an Acquired Brain Injury. 

Over several Wednesdays I will offer information on the following - 

• Anatomy of the brain - next Wednesday
• Ischemic stroke
• Transient Ischemic Attack (TIA or mini-stroke)
• Hemorragic stroke
• Stroke in children (Paediatric stroke)
• Effects of a stroke
