ABSTRACT: Signs that strongly suggest Parkinson disease (PD) include unilateral hand tremor, slowed or decreased movement, and gait changes. Postural alterations include leaning forward or asymmetric shoulder height; the arm may not swing when the patient walks, or it may be held flexed at the elbow. Patients may report increasing difficulties in occupational and social functioning. Mimics of PD include essential tremor, normal pressure hydrocephalus, other neurodegenerative diseases, and drug-induced parkinsonism. Most patients report such nonmotor symptoms as sleep disturbances, visual difficulties, bowel and bladder problems, fatigue, depression, and anxiety. Cognitive impairment in many patients takes the form of slowing of memory and difficulty with visual spatial tasks and executive function. A more realistic treatment goal than tremor eradication is improved overall mobility.
