my husband is 77 and has been haven all kinds a systems. We have seen a vascular doctor. Dizzy, lost of balance, sometimes he can not stand up straight and he scuffles when he walks. Also he has some tremors in his lower lip and hands. He is forgetful, and at times he is disoriented and/or confused. The doctor said he could have the beginning of Parkinson s and prescribe a med. it seem to work for one day and the morning of the next day. Middle of that day he lost his balance and became a little confused. I think he is having little strokes or Tia s. Also, he is lethargic and very often cold.
