In addition to motor symptoms, the nonmotor symptoms of PD are now recognized as a significant source of disability.2 Given continuing advances in therapy, it is increasingly important that clinicians recognize PD in its earliest stages. Equally critical, PD must be distinguished from less common forms of parkinsonism because prognosis and treatment may differ. In this chapter, we discuss the motor and nonmotor clinical manifestations of PD, followed by a discussion of clinical signs that can distinguish PD from other parkinsonian syndromes.
