Family Casebook Mini-Stroke
A TIA - a transient ischaemic attack - is essentially a miniature stroke which is caused by a temporary interruption in the blood flow to the brain.
Symptoms mimic a stroke and can be severe - including loss of speech and power in the limbs - but they usually only last less than 24 hours and the victim is left with no lasting disability.
However, attacks are very frightening and require a visit to hospital for assessment.
A TIA is an early warning sign that the circulation to the brain is not as healthy as it should be and can be a precursor to a full stroke.
They can be caused by many things, ranging from an irregular heartbeat to tiny blood clots, but your risk can be reduced through lifestyle changes.
You should be of a normal weight, eat a low-fat diet and not smoke.
Smoking can cause the arteries to constrict and if they are already narrowed due to fat build-up this can result in a TIA.
Dietary supplements of Omega 3 fish oils also help prevent strokes and TIAs.
There is also evidence that low doses of aspirin can help but speak to your GP before you take it.
