Abstract

Depression has been associated with reduced expression of brain‐derived neurotrophic factor ( BDNF ) in the hippocampus. Genetic association studies of the BDNF Val66Met polymorphism (rs6265) in geriatric depression have produced inconsistent results. A meta‐analysis of studies was conducted to compare the frequency of the BDNF Val66Met variant between cases with geriatric depression and age‐matched controls. A total of five studies involving 523 cases with geriatric depression and 1,220 psychiatrically healthy controls was included. Met allele carriers had an increased risk for geriatric depression when compared to Val/Val homozygotes ( P = 0.004, OR = 1.48, 95% CI = 1.13–1.93). Our findings suggest the BDNF Met allele may confer increased risk for depression as individual age. © 2012 Wiley Periodicals, Inc.

  • APOE-e4 is associated with increased risk for late-life depression.

    “At least three genes have been associated with increased risk for LLD: the methionine (Met) allele of the neurotrophic factor BDNF199, APOE-e4 (involved in myelin repair and Aβ metabolism), and SLC6A4 (the short allele of the serotonin transporter 5-HTTLPR)200.”

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.
