Abstract

Brain-derived neurotrophic factor (BDNF) Val66Met polymorphism has previously been implicated in Alzheimer's disease (AD)-related cognitive impairment. We aimed to determine the relationship between BDNF Val66Met and beta-amyloid (Aβ) on cognitive decline, hippocampal atrophy, and Aβ accumulation over 36 months in 165 healthy adults enrolled in the Australian Imaging, Biomarkers and Lifestyle study. In healthy adults with high Aβ, Met carriers showed significant and moderate-to-large declines in episodic memory, executive function, and language, and greater hippocampal atrophy over 36 months, compared with Val/Val homozygotes. BDNF Val66Met was not found to be related to rates of change in cognition or hippocampal volume in healthy adults with low Aβ. BDNF Val66Met did not relate to the amount of Aβ or to the rate of Aβ accumulation in either group. High Aβ levels coupled with Met carriage may be useful prognostic markers of accelerated cognitive decline and hippocampal degeneration in individuals in the preclinical stage of AD.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • In healthy adults with high Aβ and carrying the Met allele, the rate of hippocampal volume reduction was significantly greater.

    “In the study conducted in healthy adults having a high Aβ level and carrying the Met allele, the rate of HV reduction was significantly more.”
  • In Val/Val homozygotes with high Aβ levels, hippocampal volume reduction rate was greater than with low Aβ, irrespective of BDNF Val66Met polymorphism over 36 months.

    “A greater reduction rate in HV was observed in Val/Val homozygotes who were having high Aβ levels than with low Aβ, irrespective of their BDNF Val66Met polymorphism over 36 months.”
  • In healthy individuals, memory decline with reduction in hippocampal volume corresponds with high Aβ levels.

    “The decline in memory with the reduction in hippocampal volume (HV) corresponding with high Aβ levels has been already reported in healthy individuals; Lim et al. (2013) showed that BDNF Val66Met worsens these conditions more in the preclinical stage of AD [72].”
  • BDNF Val66Met worsens memory decline and hippocampal volume reduction in the preclinical stage of AD.

    “The decline in memory with the reduction in hippocampal volume (HV) corresponding with high Aβ levels has been already reported in healthy individuals; Lim et al. (2013) showed that BDNF Val66Met worsens these conditions more in the preclinical stage of AD [72].”

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.
