Inactivity, obesity, and insulin resistance are significant risk factors for the development of Alzheimer's disease (AD). Several studies have demonstrated that diet induced obesity, inactivity, and insulin resistance exacerbates neuropathological hallmarks of AD. The aggregation of beta-amyloid peptides is one of these hallmarks. Beta-site amyloid precursor protein cleaving enzyme 1 (BACE1) is the rate-limiting enzyme in amyloid precursor protein (APP) processing, leading to beta-amyloid peptide formation...

The mammalian target of rapamycin (mTOR) is a serine/threonine protein kinase involved in the regulation of protein synthesis and degradation, longevity and cytoskeletal formation. The mTOR pathway represents a key growth and survival pathway involved in several diseases such as cancer, obesity, cardiovascular disease and neurodegenerative diseases. Numerous studies linked the alterations of mTOR pathway to age-dependent cognitive decline, pathogenesis of Alzheimer disease (AD) and AD-like dementia in Down syndrome (DS)...

Chronic stress is a risk factor for a number of physiological disorders including cardiovascular disease, obesity and gastrointestinal disorders, as well as psychiatric and neurodegenerative disorders. There are a number of underlying molecular and cellular mechanisms altered in the course of chronic stress, which may increase the vulnerability of individuals to develop psychiatric disorders such as depression, and neurodegenerative disorders such as Alzheimer's Disease (AD). This is evident in the influence of stress on large-scale brain networks, including the resting state Default Mode Network (DMN), the effects of stress on neuronal circuitry and architecture, and the cellular and molecular adaptations to stress, which may render individuals with stress related psychiatric disorders more vulnerable to neurodegenerative disease later in life...

Several studies reported that cancer is less frequent in persons with Alzheimer's and Parkinson's Diseases (AD/PD) and vice-versa. We evaluated whether a different distribution of known nongenetic risk factors for cancer and AD/PD, might explain their inverse relationship of occurrence. We nested 2 case-control studies in a subsample of a large cohort of 1,000,000 resident in Lombardy Region in Italy (n=1515), followed-up for cancer and AD/PD occurrence since 1991 until 2012. Conditional logistic regression was performed to determine the odds ratios (OR) and 95% confidence intervals (CI) of AD/PD in subjects with and without cancer and the risk of cancer in those with and without AD/PD...

Perivascular macrophages (PVM) are a distinct population of resident brain macrophages characterized by a close association with the cerebral vasculature. PVM migrate from the yolk sac into the brain early in development and, like microglia, are likely to be a self-renewing cell population that, in the normal state, is not replenished by circulating monocytes. Increasing evidence implicates PVM in several disease processes, ranging from brain infections and immune activation to regulation of the hypothalamic-adrenal axis and neurovascular-neurocognitive dysfunction in the setting of hypertension, Alzheimer disease pathology, or obesity...

BACKGROUND: Tau is a microtubule-associated protein that becomes pathological when it undergoes hyperphosphorylation and aggregation as seen in Alzheimer's disease (AD). AD is mostly sporadic, with environmental, biological and/or genetic risks factors, interacting together to promote the disease. In the past decade, reports have suggested that obesity in midlife could be one of these risk factors. On the other hand, caloric restriction and physical exercise have been reported to reduce the incidence and outcome of obesity as well as AD...

Type 2 diabetes and obesity are possible risk factors for Alzheimer’s disease and these can be modified by physical activity and changes in dietary patterns, such as switching to a Mediterranean diet. This diet includes fruits, vegetables, olive oil, fish and moderate wine intake. These foods provide vitamins, polyphenols and unsaturated fatty acids. This diet should be able to reduce oxidative stress. The inflammatory response is also reduced by unsaturated fatty acids, resulting in a lower expression and a lower production of pro-inflammatory cytokines...

ETHNOPHARMACOLOGICAL RELEVANCE: Metabolic syndrome and vascular dysfunction was suggested to be the risk factors for Alzheimer's disease (AD). Xuefu Zhuyu decoction (XZD) is a traditional Chinese medicine used to treat metabolic syndrome and cardiac-cerebral vascular disease. The effects of XZD on ameliorating metabolic syndrome, amyloid-related pathologies and cognitive impairment in an animal model of AD with metabolic stress was investigated. MATERIALS AND METHOD: The animal model of AD with metabolic stress was created by administrating high-fat diet and a low-dose injection of streptozotocin prior to the appearance of senile plaques in APP/PS1 transgenic mice...

Alzheimer's disease (AD) represents the major form of dementia in the elderly. In recent years, accumulating evidence indicate that obesity may act as a risk factor for AD, while the genetic link between the two conditions remains unclear. This bioinformatics analysis aimed to detect the genetic link between AD and obesity on single nucleotide polymorphisms (SNPs), gene, and pathway levels based on genome-wide association studies data. A total of 31 SNPs were found to be shared by AD and obesity, which were linked to 7 genes...

Accumulating studies suggest that overnutrition-associated obesity may lead to development of type 2 diabetes mellitus and metabolic syndromes (MetS). MetS and its components are important risk factors of mild cognitive impairment, age-related cognitive decline, vascular dementia, and Alzheimer's disease. It has been recently proposed that development of a disease-course modification strategy toward early and effective risk factor management would be clinically significant in reducing the risk of metabolic disorder-initiated cognitive decline...

Americans have embraced a large number of diets in an attempt to manage obesity, improve quality of life, and address specific health problems. Among diets developed to address health problems, the ketogenic diet has had a long and variable history. Developed in the 1920s by a faith healer to help children with epilepsy, this diet induces a state that mimics carbohydrate starvation. As medications became available and effectively addressed seizures, the diet fell out of favor. During the last few decades, researchers and clinicians have learned that it can be useful in children and adults with refractory epilepsy and a variety of other conditions...

Body weight loss in late-life is known to occur at a very early stage of Alzheimer's disease (AD). Apolipoprotein E4 (ApoE4) represents a major genetic risk factor for AD and is linked to an increased cortical amyloid-β (Aβ) accumulation. Since the relationship between body weight, ApoE4, and AD pathology is poorly investigated, we aimed to evaluate whether ApoE4 allelic status modifies the association of body mass index (BMI) with markers of AD pathology. A total of 368 Aβ-positive cognitively healthy or mild cognitive impaired subjects had undergone [18F]-AV45-PET, [18F]-FDG-PET, and T1w-MRI examinations...

Polyunsaturated fatty acids (PUFAs) are lipid derivatives of omega-3 (docosahexaenoic acid, DHA, and eicosapentaenoic acid, EPA) or of omega-6 (arachidonic acid, ARA) synthesized from membrane phospholipids and used as a precursor for endocannabinoids (ECs). They mediate significant effects in the fine-tune adjustment of body homeostasis. Phyto- and synthetic cannabinoids also rule the daily life of billions worldwide, as they are involved in obesity, depression and drug addiction. Consequently, there is growing interest to reveal novel active compounds in this field...

From therapeutic point of view, it is often beneficial to enhance the expression of certain enzymes whose low expression is responsible for the observed ailment. Small molecules as activators of several enzymes have great biological potential as anti-microbial and anti-cancer agents, for the treatment of diabetes, obesity, metabolic disorders, and for the treatment of neurological disorders including Alzheimer's disease. This review covers patents describing small molecules as activators, and provides structural leads for the design of even more potent activators...

A diet with high glycaemic index, which causes rapid spikes in blood sugar level, can lead to disorders such as significantly increased risk for type 2 diabetes, cardiovascular disease and obesity. These conditions are also linked to the progression of cognitive decline and neurodegenerative diseases including Alzheimer's disease. Blackcurrant powder (BC) is a rich source of dietary fibre and bioactive compounds. Wholemeal wheat, barley and oat flours contain high amount of fibre. In this study, a model food (cookie) was developed and used to investigate the in vitro glycaemic glucose equivalent and antioxidant activities of the cookies made with three different wholemeal flours (wheat, barley and oat) with different replacement levels (5, 10 and 15%) of blackcurrant powder...

The pathophysiological actions of fatty acids (FAs) on Alzheimer's disease (AD), which are possibly mediated by genomic effects, are widely known; however, their non-genomic actions remain elusive. The aim of this study was to investigate the non-genomic mechanism of extra-cellular palmitic acid (PA) regulating beta-amyloid peptide (Aβ) production, which may provide a link between obesity and the occurrence of AD. In an obese mouse model, a high-fat diet (HFD) significantly increased the expression levels of APP and BACE1 as well as the AD pathology in the mouse brain...

After more than a century since Dr. Alois Alzheimer first described the pathological hallmarks accompanying the defining clinical features of the disease, we have yet to deliver any meaningful disease-modifying treatments to our patients. In this article, we present a rationale for the need to be "extraordinarily diverse" in seeking effective ways to treat or prevent this devastating disease. Our approach is based on applying a systems-biology perspective at the population level, using a diverse array of 'OMICS' methodologies to identify molecular mechanisms associated with well-established AD risk factors including systemic inflammation, obesity and insulin resistance...
