摘要：

Objective: To assess whether family history (FH) of Alzheimer disease (AD) alone influences AD biomarker abnormalities. Design: Adult Children Study. Setting: Washington University's Charles F. and Joanne Knight Alzheimer's Disease Research Center. Participants: A total of 269 cognitively normal middle- to older-aged individuals with and without an FH for AD. Main Outcome Measures: Clinical and cognitive measures, magnetic resonance imaging-based brain volumes, diffusion tensor imaging-based white matter microstructure, cerebrospinal fluid biomarkers, and molecular imaging of cerebral fibrillar amyloid with positron emission tomography using the [C-11] benzothiazole tracer, Pittsburgh compound B. Results: A positive FH for AD was associated with an age-related decrease of cerebrospinal fluid A beta 42; the epsilon 4 allele of apolipoprotein E (APOE4) did not alter this effect. Age-adjusted cerebrospinal fluid A beta 42 was decreased for individuals with APOE4 compared with the level for those without, and the decrease was larger for individuals with a positive FH compared with the decrease for those without. The variation of cerebrospinal fluid tau and Pittsburgh compound B mean cortical binding potential increased by age. For individuals younger than 55, an age-related increase in mean cortical binding potential was associated with APOE4 but not FH. For individuals older than 55, a positive FH and a positive APOE4 implied the fastest age-related increase in mean cortical binding potential. A positive FH was associated with decreased fractional anisotropy from diffusion tensor imaging in the genu and splenium of the corpus callosum. Conclusion: Independent of APOE4, FH is associated with age-related change of several cerebrospinal fluid, Pittsburgh compound B, and diffusion tensor imaging biomarkers in cognitively normal middle-to older-aged individuals, suggesting that non-APOE susceptibility genes for AD influence AD biomarkers.
