I only know from personal experience with my Mother that she has experienced depression (i.e., crying a lot, diminished appetite) and has had what I think are "panic attacks". The reason I think these are panic attacks is that I am subject to these myself on occasion and from what I can get her to tell me she is experiencing, they parallel my own panic attacks a great deal. She says she has trouble swallowing and doesn't feel like she can breathe. She has recently been re-started on 1 Paxil q.d. and is doing much better right now. She also experienced visual hallucinations a few times, but has not had any problem with them recently. I'd like to comment that this is all very interesting to me, talking to/reading about others actively involved in PD.
