Luella, There are lots of types of atypical PD. A movement disorder specialist might be able to get closer to a more definitive diagnosis. Unfortunately, there aren't a lot of effective medications for PD + disorders. Some of these atypical cases progress more quickly than PD. My mother Joyce (70) has a PD+ disease (striatonigral degeneration) than fortunately responds to standard PD drugs -- though those drugs don't work as well for her as they do for someone with PD. It is worth seeing a movement disorder specialist if she hasn't already. They can tell a certain amount from tests that can be done right in the office. Good luck.
