APOE ε4 moderates abnormal CSF-abeta-42 levels, while neurocognitive impairment is associated with abnormal CSF tau levels in HIV+ individuals – a cross-sectional observational study
BACKGROUND Cerebrospinal fluid (CSF) biomarkers Aβ1-42, t-tau and p-tau have a characteristic pattern in Alzheimer's Disease (AD). Their roles in HIV-associated neurocognitive disorder (HAND) remains unclear. METHODS Adults with chronic treated HIV disease were recruited (n = 43, aged 56.7 ± 7.9; 32% aged 60+; median HIV duration 20 years, >95% plasma and CSF HIV RNA <50 cp/mL, on cART for a ...
متن کاملBrain Aging and APOE ε4 Interact to Reveal Potential Neuronal Compensation in Healthy Older Adults
Compensation implies the recruitment of additional neuronal resources to prevent the detrimental effect of age-related neuronal decline on cognition. Recently suggested statistical models comprise behavioral performance, brain activation, and measures related to aging- or disease-specific pathological burden to characterize compensation. Higher chronological age as well as the APOE ε4 allele ar...
متن کاملAPOE ε4 and lipid levels affect risk of recurrent nonlobar intracerebral hemorrhage.
OBJECTIVE Genetic variants ε2/ε4 within the APOE gene are established risk factors for lobar intracerebral hemorrhage (ICH). Published preliminary data suggest a potential role for APOE ε4 in risk of nonlobar ICH. We therefore investigated the role of APOE in recurrent nonlobar ICH, and sought to clarify whether effects of APOE on circulating lipids mediate this association. METHODS Three hun...
متن کاملAccelerated Cell Aging in Female APOE-ε4 Carriers: Implications for Hormone Therapy Use
Apolipoprotein-ε4 (APOE-ε4) is a major genetic risk factor for cognitive decline, Alzheimer's disease (AD) and early mortality. An accelerated rate of biological aging could contribute to this increased risk. Here, we determined whether APOE-ε4 status impacts leukocyte telomere length (TL) and the rate of cellular senescence in healthy mid-life women and, further, whether hormone replacement th...
متن کاملSex and APOE: A memory advantage in male APOE ε4 carriers in midlife
Short-term memory in middle-aged individuals with different APOE alleles was examined using a recently developed task which is sensitive to medial temporal lobe (MTL) damage. Individuals (age-range: 40-51 years) with ε3/ε3, ε3/ε4 and ε4/ε4 APOE genotypes (N = 60) performed a delayed estimation task with a sensitive continuous measure of report. The paradigm allowed us to measure memory for item...
