my dad was diagnosed with psp this year. the thing I here a lot is peoplr who know someone with psp say they fall backwards. my dad seems to be getting worse buy the week. he does not fall much maybe once a month and when he falls he falls forward not backwards. I have noticed he has problems lifting his legs up when he is sitting. my question is do you still get worse with out the falling involed, I here a lot of people say there spouse or loved one falls all the time . but dad does not and he seems to be getting worse.
