A mini stroke occurs when part of the brain is deprived of oxygen for a short time.
The symptoms are mild: weakness or temporary loss of a body part that can go away after 24 hours.
As a result, some patients may not seek medical attention. But a study in the American Heart Association's Stroke journal finds that without medical intervention after a mini stroke damage could be far more serious.
Scientists found the disabilities of many patients who received no initial medical or preventive therapy deteriorated significantly.
