Stroke is one of the leading causes of death.
700,000 people experience a stroke each year, and 160,000 of them are fatal. Stroke is characterized by the sudden loss of circulation to an area of the brain, resulting in a corresponding loss of neurologic function. The combined incidence of both VAD and CAD is estimated to be 2.6 per 100,000. The path of the Vertebral Artery is well described elsewhere. This is the most common site for VAD associated with cervical manipulation.
