Carey,
Have you been responsive or to or tried an SSRI? It has been life restorer for my anxiety. I think mood disorders may be a defining symptom of PD, and they know so little about it.
Not only that, but it turns out Serotonin works closely with Dopamine neurons and actually seem to attack alpha-synuclein aggregation in mid cycle of becoming toxic. I think this is pretty amazing, yet we here nothing about it.
It has also been established that depression is not from depletion of serotonin but rather an effect or result of impaired Tryptophan production. Mrs. D recommends taking Tryptophan supplement see halfway down the thread

(the factoids above cited in the thread linked here)
I am glad to see they acknowledge that they see an SSRI may further muck things up for PD patients.
