What can I do for my mother with Parkinson's Disease?

My mother is only 59 with moderately advanced Parkinson's Disease. She has lost her job, and lives by herself 8 hours away from me, her nearest relative. Her handling of money has become increasingly irresponsible to the point that she has cut down or completely stopped her medication. She has isolated herself from almost everyone, and lied to me about getting help from disability services. I am 29, pregnant with my first child, and have no idea what to do.
