This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they exist. The article ends with the authors’ clinical recommendations. A 62-year-old man presents with an intermittent tremor in his left hand and some
vague discomfort in the left arm. Physical examination shows a minimal rest tremor
in the left hand that disappears with use of the limb, mild rigidity at the left wrist and
elbow, slowness of finger tapping with the left hand, and decreased arm swing on the
left while walking. How should he be evaluated and treated?

creased mortality.6,7 Parkinson’s disease is caused by the disruption of dopaminergic neurotransmission in the basal ganglia. On pathological examination, the dopaminergic neurons in thesubstantia nigra are markedly reduced, and Lewy bodies (cytoplasmic inclusions) arepresent in the residual dopaminergic neurons.
More than 10 autosomal dominant and recessive genes or gene loci have been linked to Parkinson’s disease, but mutation in a single gene is an uncommon cause.8 Never-theless, 10 to 15 percent of people with Parkinson’s disease will have an affected first-degree or second-degree relative.9 No clear environmental determinants of Parkinson’sdisease have been identified.2 s t r a t e g i e s a n d e v i d e n c e d i a g n o s i s
The diagnosis of Parkinson’s disease is based on the presence of the core features ofslowness and paucity of movement (bradykinesia and akinesia) and tremor when thelimb is at rest or resistance to passive movement of the joints (rigidity), or both.10,11 Pos-tural abnormalities are often included in the definition but generally occur later in thecourse of the disorder and are nonspecific, making them of little clinical usefulness inearly disease.11 There are four common presentations of Parkinson’s disease: tremor, Downloaded from at HARVARD UNIVERSITY on October 2, 2006 .
