Head injury and risk of Parkinson disease: A systematic review and meta‐analysis

Abstract

Head trauma has been implicated in the etiopathogenesis of Parkinson's disease (PD). We performed a meta‐analysis to investigate the association between head trauma and the risk of developing PD. We included observational studies if they (1) clearly defined PD, (2) defined head trauma leading to concussion, and (3) presented odds ratios (ORs) and 95% confidence intervals (CIs) or provided data to compute these statistics. Random effect model was used to estimate the pooled, adjusted OR. Heterogeneity between studies was evaluated with the Q test and the I 2 statistic. We conducted a sensitivity analysis to assess the influence of each study and repeated the analysis by excluding the studies with the largest weights. We used funnel plot to assess the presence of publication bias. After reviewing more than 636 article titles, 34 articles were selected for full review. In total, 22 studies (19 case–control studies, 2 nested case–control studies, and 1 cohort study) were included in the meta‐analysis. The pooled OR for the association of PD and head trauma was 1.57 (95% CI, 1.35–1.83). The results of our meta‐analysis indicate that a history of head trauma that results in concussion is associated with a higher risk of developing PD. © 2013 Movement Disorder Society

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Repeated mTBI is a major risk factor for neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, fronto-temporal dementia, and chronic traumatic encephalopathy.

    “In particular, repeated mTBI (rmTBI) has been identified as a major risk factor for neurodegenerative diseases including Alzheimer’s disease (AD) [100], Parkinson’s disease (PD) [68] amyotrophic lateral sclerosis (ALS) [21, 2], fronto-temporal dementia (FTD) [126, 124], and chronic traumatic encephalopathy (CTE) [95].”

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.
