What causes recurrent light-headedness?
Patient: PAST YEAR EXPERIENCE LITE HEADEDNESS. HAVE BEEN TO HOSPITAL 3 TIMES. MIR, CAT- SCAN EKG, EEG. CHECKED CORTID ARTERIES, BLOOD FLOW. ALL OK I AM TOLD. REACHING OUT FOR OTHER IDEAS. LOST 20 LBS PER DOC ORDERS. THESE ATTACKS LAST ABOUT 2 MINUTES. LAST 1 ABOUT 3 HOURS AGO. 64 yrs old. Doctor: Well come to HCMThank for asking,I really appreciate your concern, if the concern tests are unremarkable as long as the headache are concern then it could be migraine and nothing could be else, it is a kind of depression and anxiety causes the symptoms and it may aggravates the migraine, such symptoms pretty common in female, I would suggest Tab Carbamazepine 200 mg once in day,  hope this information helps.
