Parkinson's disease (PD) is a progressive disorder of the nervous system that affects movement. It is characterized by bradykinesia (slowness of movement), tremor, rigidity (stiffness of the limbs and trunk), and postural instability (impaired balance and coordination). Comorbidities such as mental disorders, autonomic dysfunction (problems with the autonomic nervous system, which controls involuntary body functions such as heart rate, blood pressure, digestion, and temperature regulation), difficulties in swallowing and speech, as well as sleep impairment may occur during the course of the disease.
