My mother is recovering from her 2nd TIA which occured 5 wks ago and the only obvious signs of her attack were short term memory loss until a few days ago. She has started comlaining about an excessive dry mouth, thirst and constant trips to the ladies. Along with these symptons she is experiencing shaking periods where her whole body shakes for around 45mins then it subsides and she feels normal again. The thirst increases prior to and during these attacks. Blood tests have come back normal. Has anyone experienced anything similar or has any indications as to what this can be?
