My mother who turned 70 a couple of weeks ago was diagnosed with PSP about a year ago, they reckon she's probably had it for at least 5 yrs already. She has been in denial since diagnosis and says they've got it all wrong!! She definitely has it unfortunately and has every symptom going, which has progressed rather quickly now, it is so sad to watch her deteriorate. We even had a second opinion to help her come to terms with it, but she still doesn't want to. It is very hard to watch and very hard to help her but we are trying to make her as comfortable as possible. She has become a very difficult person but there are flashes of my Mum at times.
