Stroke
A stroke, or Cardio-Vascular Accident (CVA) is when there is a reduction to the flow of blood to the brain causing damage to brain tissue.
As different parts of the brain control different parts of the body, the extent and part of the body affected by the stroke will depend on what part of the brain is damaged.
Symptoms like weakness in one arm or leg, difficulty with speech, understanding, reading, writing or making sense of what you see, hear and touch are most common.
During a stroke, brain cells are damaged and others die. The dead brain cells cannot regenerate, however the undamaged nerve cells around the dead cells may take over as the swelling caused by the stroke reduces. It is also possible that other parts of the brain can learn to take over from areas that have died. Although the most recovery happens in the first few months following a stroke, individuals can continue to recover and make gains for several years after the initial event.
There are two main types of stroke: Ischaemic and haemorrhagic.
The Ischaemic Stroke
This is the most common type of stroke where there is a blockage in the vascular system within the brain. Blood, and therefore oxygen, is restricted causing damage to areas beyond the blockage. This may result in physical and psychological disability of varying degrees depending on the area of the brain affected.
The Haemorrhagic Stroke
This type of stroke is less common however it may lead to more severe neurological deficits. As opposed to an ischaemic stroke, the haemorrhagic stroke is where there is a leakage of blood from the blood vessels within the brain, creating a lack of oxygen to the nerve cells beyond the leak. Damage is more widespread initially due to the amount of blood that has leaked within the brain and, secondarily, as a result of an increase in pressure on surrounding brain tissue.
Transient Ischaemic Attack (mini-stroke)
A transient Ischaemic Attack (TIA) is often called a mini-stroke, and happens when the blood supply to the brain is interrupted for a short time.
The symptoms are very similar to a stroke (such as weakness on one side of the body, loss of sight and slurred speech) but they are temporary. A TIA may last for just a few minutes or even hours. The symptoms will then disappear completely within 24 hours.
A TIA can be a warning sign prior to a stroke therefore medical assistance should be sought as a matter of urgency.
