I have read that one of the factors that distinguishes one of the Parkinson's Plus diseases (striatonigral degeneration) from PD is early gait/balance problems. According to what I recently read, with PD gait/balance problems may occur several years after diagnosis, whereas with SND, it appears early on. Is there anyone on the list with PD that's had early balance/gait problems? Thanks. Debbie White [log in to unmask]
