In view that several studies have shown a positive correlation between high cholesterol and an increase in the risk for developing Alzheimer’s disease (AD) statins have been proposed as alternative drugs for its treatment and/or prevention. However, the potential benefits of statins remain controversial. Although they have lipid-lowering properties, statins also have pleiotropic effects that are unrelated to cholesterol reducti Read More

Accumulating research supports the neuroprotective effects of pomegranate (Punica granatum) juice and extracts against Alzheimer’s disease (AD) but there is limited data available in animal models. Here we investigated the effects of a standardized pomegranate extract (PE) on AD pathology in an aged transgenic AD animal model (R1.40).The mice (age 24-30 months) received either PE (at 100 and 200 mg/kg) or a control sol Read More

Despite B vitamin supplementation playing an important role in cognitive function, the exact effect remains unknown. The aim of this study was to systematically review and quantitatively synthesize the efficacy of treatment with vitamins B supplementation in slowing the rate of cognitive, behavioral, functional and global decline in individuals with MCI or AD. A systematic literature search in PubMed, EMBASE, International Read More

Background: Impairment in instrumental activities of daily living (IADL) starts as individuals with amnestic mild cognitive impairment (MCI) transition to Alzheimer’s disease (AD) dementia. However, most IADL scales have not shown IADL alterations in clinically normal (CN) elderly. The objective of this study was to determine which of the IADL-related Everyday Cognition (ECog) scale items are most sensitive for detection of early fu Read More

Diabetes is a well-known risk factor for Alzheimer`s disease (AD) development in the elderly. The molecular link between diabetes and AD is still not completely understood. Recent evidence suggests that platelet activation observed in diabetes may contribute to AD development. The present review summarizes the common molecular mechanisms involved in the pathophysiology of diabetes and AD and suggests novel therape Read More

Background: Alzheimer's disease (AD) is the most common type of age-related dementia. Effective anti-AD drugs against amyloid-β-protein-induced cognitive impairment are still lacking. Baicalein is the main component of Radix Scutellariae and has neuroprotective properties. In this study, we provide further insights into pharmacotherapy mechanisms and potential targets of baicalein in AD. Objective: To investigate the therap Read More

Alzheimer’s disease (AD) is the most common reason for dementia in elderly population. Its neuropathological features include senile plaques, neurofibril tangles and neuronal death. Scientists have established many AD animal models, including yeast, Caenorhabditis elegans, Drosophila melanogaster, mice, rats and non-human primates. Drosophila AD models are much more efficient for genetic manipulation and screeni Read More

We previously reported on enhanced susceptibility to death of lymphocytes from Alzheimer’s disease (AD) patients when exposed to hydrogen peroxide (H2O2)-induced oxidative stress and an increased resistance to death in those of patients with a history of skin cancer. This is consistent with our hypothesis proposing that the cellular machinery controlling cell death is deregulated in opposite directions in Alzheimer’s disea Read More

Background: Previous studies relating smoking and alcohol drinking with the incidence of dementia have been inconsistent. Objectives: We assessed whether smoking and alcohol drinking was associated with the risk of dementia, including Alzheimer disease (AD) and vascular dementia (VaD) after seven years of follow-up. Design: We prospectively analysed the incidence of dementia from 2004 to 2011 among 2959 elde Read More
