I submit to you these facts and reflections:
1) Today I found a marriage in which the man has been diagnosed PSP early, 7 months ago. He has taken our experience in gymnastics and speech therapy and applies it with intensity and rigor every day. It even overflows them in dedicated time.
2) A neighbor who suffers from a neurological disease that affects only the legs. It is a "rare" disease in the family of Amyotrophic Lateral Sclerosis. He was given a couple of years to live. In addition to his treatment he does swimming every day (2000 meters). Of this is 12 years ago.
3) I wonder if one of the primary research goal for PSP would be: early diagnosis and specific intensive gymnastics as soon as it is detected.
