<s>[INST] 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. [/INST] Well come to ChatDoctorThank 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 aggravate the migraine, such symptoms pretty common in female, I would suggest Tab Carbamazepine 200 mg once in day, hope this information helps. </s>
