Increased risk of dementia in mothers of Alzheimer's disease cases: Evidence for maternal inheritance

Abstract

This study tests the hypothesis of maternal inheritance of AD in families of 118 subjects with this disorder enrolled in The Consortium to Establish a Registry for Alzheimer's Disease (CERAD). The parental generation included 24 subjects with dementia. Using the Cox proportional hazards model, we found the age-adjusted mother-to-father relative risk to be 2.8 (95% CI, 1.1 to 7.7). Among a subset of 10 families with one affected parent and at least two affected siblings, the ratio of affected mothers-to-fathers was 9:1. These findings support recent studies that found a high mother-to-father ratio among affected parents of subjects with AD. Together, these results suggest maternal inheritance of AD and are consistent with several hypotheses regarding the genetic nature of AD.

  • Both mothers and fathers contribute to their offspring's AD risk, but mothers contribute more because mtDNA is maternally inherited.

    “In this respect, both mothers and fathers contribute to their offspring's AD risk, but because mitochondrial DNA (mtDNA) is maternally inherited mothers contribute more.”
  • Cognitively normal, middle-aged individuals with AD mothers have a higher risk of developing AD than middle-aged individuals with AD fathers or no AD-affected parents.

    “Cognitively normal, middle-aged individuals with AD mothers, who have a higher risk of developing AD than middle aged individuals with AD fathers or no AD-affected parents [131], have relatively low platelet COX activities [132].”

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.
