A number of genetic risk factors have been identified for Alzheimer's disease (AD) including genes involved in the inflammatory response (interleukin 1A, [IL-1α (-889)], interleukin 1B (IL-1β [+3953]), and tumor necrosis factor (TNF [-308 and -850]). We investigated the prevalence and functional consequences (baseline cognitive performance, plasma cytokine(More)
BACKGROUND/AIMS Luteinizing hormone (LH) has been shown to alter the metabolism of beta amyloid (Aβ), a key protein in Alzheimer's disease (AD) pathogenesis. While LH and components required for LH receptor signalling are present in the brain, their role in the CNS remains unclear. In vitro, LH has been shown to facilitate neurosteroid production and alter(More)
BACKGROUND Inflammatory changes are a prominent feature of brains affected by Alzheimer's disease (AD). Activated glial cells release inflammatory cytokines which modulate the neurodegenerative process. These cytokines are encoded by genes representing several interleukins and TNFA, which are associated with AD. The gene coding for HLA-B associated(More)
Presenilin-1 mutations account for nearly 50% of all early-onset familial cases of Alzheimer's disease. Most of these mutations are completely penetrant, although the recently described Glu318Gly substitution seems to have only partial penetrance. These findings suggest that the Glu318Gly mutation may work as a genetic risk factor for Alzheimer's disease.(More)
Cognitive decline and dementia due to Alzheimer's disease (AD) have been associated with genetic, lifestyle, and environmental factors. A number of potentially modifiable risk factors should be taken into account when preventive or ameliorative interventions targeting dementia and its preclinical stages are investigated. Bone mineral density (BMD) and body(More)
Purpose/Aim of the study: Poor cardiovascular health, including obesity and altered lipid profiles at mid-life, are linked to increased risk of Alzheimer's disease (AD). The biological mechanisms linking cardiovascular health and cognitive function are unclear though are likely to be multifactorial. This study examined the association between various(More)
