Study Notes

Parkinson's Disease Clinical Manifestations

Parkinson's Disease (PD) has a gradual onset and symptoms progress slowly over a chronic, prolonged course.
Cardinal signs of PD are tremor, rigidity, bradykinesia/akinesia, and postural instability.
PD has two major subtypes: tremor dominant and nontremor dominant.
Tremor in PD is a slow, unilateral resting tremor that disappears with purposeful movement and during sleep.
Rigidity in PD is characterized by resistance to passive limb movement and involuntary stiffness.
Bradykinesia is a common feature of PD, referring to the overall slowing of active movement.
Postural instability in PD leads to gait problems, propulsive gait, and an increased risk of falls.
PD also produces autonomic symptoms, including sweating, drooling, flushing, hypotension, and gastrointestinal/urinary issues.
Psychiatric changes in PD include depression, anxiety, dementia, delirium, hallucinations, and psychosis.
Cognitive changes in PD include diminished executive functions and eventual dementia in a majority of patients.
PD patients may also experience hypokinesia, freezing phenomenon, micrographia, dysphonia, dysphagia, and complications such as infections and falls.
Medications used to treat PD symptoms are associated with complications such as dyskinesia and orthostatic hypotension.
