Abstract

A method and apparatus diagnose a circulation disorder in a patient, and in particular, predict whether a patient is likely to suffer a stroke. The diagnosis is made based on a patient's responses to questions regarding whether the patient has experienced symptoms of a neurological disorder, and based on sensed electrical brain activity and sensed blood pulse activity. The pulse measurements may be taken at the patient's head, and/or at the patient's arms and/or legs. The diagnosis may be based upon a comparison of the patient's electrical brain activity on the right and left sides of the patient's brain, and on a comparison of the pulse activity on the right and left sides of the patient's head, arms and legs. The diagnosis may also be based on the patient's electrical heart activity. The diagnosis may further be based on the results of a stress test that measures the patient's blood pressure, pulse rate and anxiety level. Such a stress test may be performed before and/or after the patient's electrical brain activity, blood pulse activity and electrical heart activity have been measured. The diagnosis may also be based on whether the patient exhibits one or more arteriosclerosis risk factors and based on patient data such as age, weight, height, sex, blood cholesterol level and blood sugar level.
