He has PSP and his quality of life is suffering at home? We live in dad's house with him, his mobility is very bad and falls almost every day. He recently broke his hip. He is now on the waiting list for high care. I just know he will fight every inch of he way to stay home, but it's getting to be too hard on a daily basis.
Progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and multiple system atrophy (MSA), are little-known but disabling brain diseases, sometimes called atypical Parkinsonian disorders. These rare neurodegenerative diseases are often misdiagnosed as Parkinson's disease, amyotrophic lateral sclerosis (ALS), or Alzheimer’s disease. PSP, CBD and MSA lead to progressive decline, and although symptomatic treatment exists, there is no known cause or cure
