Fortnightly Review: Parkinsonism—recognition and differential diagnosis

Open access
Quinn, Niall·1995·BMJ

Abstract

Summary points: The cumulative lifetime risk of a person developing parkinsonism has been estimated at 1 in 40 Idiopathic Parkinson's disease is the commonest cause, but about a third of patients with the syndrome of parkinsonism or a diagnosis of Parkinson's disease have some other disease instead The diagnosis of Parkinson's disease is entirely clinical, but the results of certain investigations may help in recognising alternative causes for parkinsonism For a diagnosis of established parkinsonism, upper body akinesia must be present; rigidity is usually, but not always, present; tremor is an optional extra The two conditions that are most commonly misdiagnosed as Parkinson's disease—essential tremor and arteriosclerotic pseudoparkinsonism—do not display true parkinsonism

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
