New insights into the cause of Parkinson's disease
Abstract
Current concepts as to the cause of Parkinson's disease (PD) suggest an inherited predisposition to environmental or endogenous toxic agents. Study of the substantia nigra after death in PD has highlighted three major changes: (1) evidence of oxidative stress and depletion of reduced glutathione; (2) high levels of total iron, with reduced ferritin buffering; and (3) mitochondrial complex I deficiency. Which of these is the primary event, generating a secondary cascade of changes culminating in nigral cell death, is unknown. In presymptomatic Lewy body-positive control brains, the nigra shows depletion of reduced glutathione content and, possibly, a reduction of complex I activity. Whatever the significance of these various abnormalities, be they causal or secondary, they provide novel targets for the development of new strategies to treat the cause of PD.

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.
