Since the original publication of James Parkinson’s Essay of the Shaking Palsy in 1817, substantial strides have been made to understand the neurobiology of Parkinson disease (PD). Previously, PD was only considered as a diagnosis based on the observed motor phenomena of tremor, bradykinesia, and characteristic balance and gait disorders. However, the field of neurobehavioral disorders has now recognized the presence of several “nonmotor” phenomena as possible symptoms of PD that may unlock the mysteries of the pathogenesis of this complex neurodegenerative disorder. From the presence of olfactory dysfunction and dysautonomia to the recognition of cognitive impairment and mood and behavioral disorders, PD is a heterogeneous disorder. To the best of my knowledge, Neuropsychiatry and Cognitive Changes in Parkinson’s Disease and Related Movement Disorders is the first book dedicated to summarizing the advancements in the important field of neurobehavioral comorbidities in PD.
