My father and mother both died with alzheimers disease and the past few days I have been experiencing symptons such as problems remembering things. Day before yesterday my whole body began shaking and trembling. That night I woke up 6 or 7 times and had to urinate. While I was driving I had to focus on where I was going to places I ve just driven to in the past. I feel lightheaded most of the time. Could I be coming down with alzheimers?
