A cholesteryl ester transfer protein (CETP) genotype (V/V homozygosity for I405V, NCBI dbSNP rs5882) has been associated with preservation of cognitive function in old age, in addition to its associations with exceptional longevity and cardiovascular disease. We tested the hypotheses that this polymorphism was associated with either level of cognitive function or lifetime cognitive change in 525 participants who took part in the Scottish Mental Survey of 1932. Participants took the same well-validated mental ability test at ages 11 and 79.

CONTEXT: Polymorphisms in the cholesteryl ester transfer protein (CETP) gene have been associated with exceptional longevity and lower cardiovascular risk, but associations with memory decline and dementia risk are unclear. OBJECTIVE: To test the hypothesis that a single-nucleotide polymorphism (SNP) at CETP codon 405 (isoleucine to valine V405; SNP rs5882) is associated with a lower rate of memory decline and lower risk of incident dementia, including Alzheimer disease (AD).

OBJECTIVES: To determine whether offspring of parents with exceptional longevity (OPEL) have a lower rate of dementia than offspring of parents with usual survival (OPUS). DESIGN: Community-based prospective cohort study. SETTING: Bronx, New York. PARTICIPANTS: A volunteer sample of 424 community-residing older adults without dementia aged 75 to 85 recruited from Bronx County starting in 1980 and followed for up to 23 years. MEASUREMENTS: Epidemiological, clinical, and neuropsychological assessments were completed every 12 to 18 months.

Niemann-Pick type C (NPC) disease, an autosomal recessive disorder caused primarily by loss-of-function mutations in NPC1 gene, is characterized neuropathologically by intracellular cholesterol accumulation, gliosis and neuronal loss in selected brain regions. Recent studies have shown that NPC disease exhibits intriguing parallels with Alzheimer's disease (AD), including the presence of tau-positive neurofibrillary tangles (NFTs) and ?-amyloid (A?)-related peptides in vulnerable brain regions. Since enhanced cholesterol level, which acts as a risk factor for AD, can increase A?

Alzheimer's disease (AD) is the most common cause of dementia in the elderly. With an increasing longevity and the absence of a cure, AD has become not only a major health problem but also a heavy social and economic burden worldwide. In addition to the presence of abundant intra- and extra-cellular neurotoxic amyloid ? (A?) peptides, which form the amyloid plaques, and intracellular hyperphosphorylated tau protein, the main component of neurofibrillary tangles, consistent evidence indicates that the AD brain is characterized by extensive neuroinflammatory processes.

This article, based on scientific research and clinical observations, suggests that memory loss is not an inevitable consequence of aging and that Alzheimer's disease can be prevented and reversed using an integrated medical approach. Three new associations with memory loss other than age, heredity, and genetics are described. They include a high-fat diet, chronic unbalanced stress with its attendant risk in the adrenal hormone cortisol, and the presence of cardiovascular disease. A 4-pillar integrative medical program on brain longevity is presented.

Research studies clearly indicate that age-related changes in cellular and tissue function are linked to decreases in the anabolic hormones, growth hormone and insulin-like growth factor (IGF)-1. Although there has been extensive research on the effects of these hormones on bone and muscle mass, their effect on cerebrovascular and brain ageing has received little attention.

?yurveda, the science (ved) of life (ayu), owing its origin to Veda, the oldest recorded wisdom of human civilization written in 3500 BCE, contains extensive knowledge of various diseases and their therapeutic approaches. It essentially relied on nature and the immune system of an individual, and therapeutic interventions were introduced only to augment the immune system. ?yurveda had eight specialties, including psycho-neuroscience (a combination of psychology, clinical psychology and psychiatry) and a unique promotive therapy encompassing nutrition, rejuvenation and geriatrics.

Epidemiological evidence implies a role for chronic stress and stress-related disorders in the etiopathogenesis of sporadic Alzheimer's disease (AD). Although chronic stress exposure during various stages of life has been shown to exacerbate AD-related cognitive deficits and neuropathology in AD mouse models, the role of stress exposure during the prenatal period on AD development and progression remained to be investigated.
