As we all know, vertigo is one of the indicating symptoms of stroke. As stroke is well known of the ‘three highs and one low’ characteristic, it’s important to pay special attention to the symptom of vertigo in order to prevent stroke before its onset.

The research provides supportive evidence for the theoretical research of stroke indicatives, and clinical application for diagnosing and preventing of stroke.
