Parkinson's Disease: Non-Motor and Non-Dopaminergic Features

Parkinson's Disease has traditionally been seen as a movement disorder, and diagnosed by the development of tremor. However, we are beginning to understand that the disease manifests itself in many ways, and that earlier diagnosis might be possible through non-tremor symptoms. This textbook aims to tell the full story of non-motor and non-dopaminergic features of Parkinson's Disease.
