'Mini' stroke can cause major disability if untreated

September 13, 2012

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.
