It is widely believed that light-to-moderate alcohol intake may protect against dementia while excessive drinking may instead increase the risk. Nonetheless, these findings need cautious interpretations due to varying methodologies and lack of standard definition, which hindered our transferring into preventative practice. The objective of this study is to investigate the potential dose-response association between alcohol consumption and risk of dementia. A systematic search was conducted in electronic databases to identify relevant studies...

BACKGROUND: The mitochondrial enzyme amyloid beta-binding alcohol dehydrogenase (ABAD) also known as 17β-hydroxysteroid dehydrogenase type 10 (17β-HSD10) has been connected with the pathogenesis of Alzheimer's disease (AD). ABAD/ 17β-HSD10 is a binding site for the amyloid-beta peptide (Aβ) inside the mitochondrial matrix where it exacerbates Aβ toxicity. Interaction between these two proteins triggers a series of events leading to mitochondrial dysfunction as seen in AD. METHODS: As ABAD's enzymatic activity is required for mediating Aβ toxicity, its inhibition presents a promising strategy for AD treatment...

Impaired cholinergic neurotransmission associated with cognitive dysfunction occurs in various mental disorders of different etiologies including Alzheimer's disease and postalcoholic dementia and others. To address the question whether there exists a common endophenotype with a defined genetic and/or epigenetic signature causing mental dysfunction in these disorders, we investigated 2 generations of offspring born to alcohol-treated mothers. Here, we show that memory impairment and reduced synthesis of acetylcholine occurs in both F1 (exposed to ethanol in utero) and F2 generation (never been exposed to ethanol)...

Madhavi Kanuru, Gopala Krishna Aradhyam
Calnuc is a ubiquitously expressed protein of the EF-hand Ca(2+)-binding superfamily. Previous studies have implicated it in Ca(2+)-sensitive physiological processes, whereas details of its function and involvement in human diseases are lacking. Drawing upon the sequence homology of calnuc with calreticulin, we propose it functions as a molecular chaperone-like protein. In cells under thermal, chemical [urea and guanidinium chloride (GdmCl)], and acidic stress, calnuc exhibits properties similar to those of established chaperone-like proteins (GRP78, spectrin, and α-crystallin), effectively demonstrated by its ability to suppress aggregation of malate dehydrogenase (MDH), alcohol dehydrogenase, and catalase...

The opinions about optimal proportions of macronutrients in a healthy diet have changed significantly over the last century. At the same time nutritional sciences failed to provide strong evidence backing up any of the variety of views on macronutrient proportions. Herein we present an idea how these proportions can be calculated to find an optimal balance of macronutrients with respect to prevention of Alzheimer's Disease (AD) and dementia. These calculations are based on our published observation that per capita personal income (PCPI) in the USA correlates with age-adjusted death rates for AD (AADR)...

REVIEW
Suzanne M de la Monte
Alzheimer's disease (AD) should be regarded as a degenerative metabolic disease caused by brain insulin resistance and deficiency, and overlapping with the molecular, biochemical, pathophysiological, and metabolic dysfunctions in diabetes mellitus, non-alcoholic fatty liver disease, and metabolic syndrome. Although most of the diagnostic and therapeutic approaches over the past several decades have focused on amyloid-beta (Aβ42) and aberrantly phosphorylated tau, which could be caused by consequences of brain insulin resistance, the broader array of pathologies including white matter atrophy with loss of myelinated fibrils and leukoaraiosis, non-Aβ42 microvascular disease, dysregulated lipid metabolism, mitochondrial dysfunction, astrocytic gliosis, neuro-inflammation, and loss of synapses vis-à-vis growth of dystrophic neurites, is not readily accounted for by Aβ42 accumulations, but could be explained by dysregulated insulin/IGF-1 signaling with attendant impairments in signal transduction and gene expression...

Coronary artery disease (CAD) is a complex human disease, involving multiple genes and their nonlinear interactions, which often act in a modular fashion. Genome-wide single nucleotide polymorphism (SNP) profiling provides an effective technique to unravel these underlying genetic interplays or their functional involvements for CAD. This study aimed to identify the susceptible pathways and modules for CAD based on SNP omics. First, the Wellcome Trust Case Control Consortium (WTCCC) SNP datasets of CAD and control samples were used to assess the joint effect of multiple genetic variants at the pathway level, using logistic kernel machine regression model...

BACKGROUND: there are no previous studies linking repeated heat exposure of sauna and the risk of memory diseases. We aimed to investigate whether frequency of sauna bathing is associated with risk of dementia and Alzheimer's disease. SETTING: prospective population-based study. METHODS: the frequency of sauna bathing was assessed at baseline in the Kuopio Ischaemic Heart Disease population-based prospective cohort study of 2,315 apparently healthy men aged 42-60 years at baseline, with baseline examinations conducted between 1984 and 1989...

AIMS: To investigate the underlying neurobiology between alcohol use, misuse and dependence and cognitive impairment, particularly Alzheimer's disease (AD). METHODS: Review of the literature using searches of Medline, Pubmed, EMBASE, PsycInfo, and meeting abstracts and presentations. RESULTS: The role of alcohol as a risk factor and contributor for cognitive decline associated with AD has received little attention. This is despite the high prevalence of alcohol use, the potential reversibility of a degree of cognitive impairment and the global burden of AD...

OBJECTIVE: Squalor affects 1 in 1000 older people and is regarded as a secondary condition to other primary disorders such as dementia, intellectual impairment and alcohol abuse. Squalor frequently is associated with hoarding behaviour. We compared the neuropsychological profile of people living in squalor associated with hoarding to those presenting with squalor only. METHODS: This study is a retrospective case series of hospital inpatient and community healthcare services of 69 people living in squalor (49 from aged care, 16 from aged psychiatry, 3 from acute medical and 1 from a memory clinic)...

Memantine is a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist used in the treatment of moderate to severe dementia including the symptoms of Alzheimer's disease (AD). It is administered orally but compliance, swallowing problems and the routine use of multiple medications in elderly AD patients means that an alternative route of administration would be of interest. The aim of the present study was to develop memantine hydrochloride occlusive transdermal therapeutic systems (TTS) for passive and iontophoretic delivery across the skin...

BACKGROUND: Lack of a health advocacy curriculum and clarity are obstacles for effectively teaching neurology health advocacy (NHA) to neurology residents. Our purpose is to assess the need and develop content for a NHA curriculum and to describe its underlying components. METHODS: This is a cross-sectional study with two steps. In step one, neurologists and neurology residents at University of Calgary were surveyed about their perception of teaching NHA and asked to rank 56 neurological diseases on a Likert scale based on how well they lend themselves to teaching health advocacy...

A potential neuroprotective role for magnesium in neurological disease has been appreciated for almost three decades, yet translation to the clinical arena has proven elusive. Accumulating experimental evidence continues to suggest that magnesium plays a critical role in a number of neurological conditions including headache, stress, alcohol/drug intoxication, acute brain injury, seizures, Parkinson's disease and Alzheimer's disease. Simple administration of a magnesium salt in these conditions has not always been therapeutically successful, with a number of studies showing poor penetration of serum magnesium across the blood brain barrier...

Heart disease, stroke, and kidney failure are leading causes of death worldwide, and hypertension is a significant risk factor for each. Hypertension is less common in women, compared to men, in those younger than 45 years of age. This trend is reversed in those 65 years and older. In the US between 2011-2014, the prevalence of hypertension in women and men by age group was 6% vs 8% (18-39 years), 30% vs 35% (40-59 years), and 67% vs 63% (60 years and over). Awareness, treatment, and control rates differ between genders with women being more aware of their diagnosis (85% vs 80%), more likely to take their medications (81% vs 71%) and more frequently having controlled hypertension (55% vs 49%)...

Hypertension is one of the strongest risk factor for cardiovascular disease. Recently, accumulating evidence also indicates that hypertension has been linked with non-cardiovascular diseases including dementia, cancer, oral health diseases and so on. In general, elderly individuals tend to have multiple diseases as getting older. Preventing of hypertension is also benefit for other diseases.In the Hisayama Study, hypertension increased the risk of vascular dementia, but were not associated with an increased risk of Alzheimer disease, and that subjects with hypertension in midlife and normotension and hypertension in late-life increased risks of incident vascular dementia...

BACKGROUND: Orthostatic hypotension (OH) is a common cause of transient cerebral hypoperfusion in the population. Cerebral hypoperfusion is widely implicated in cognitive impairment, but whether OH contributes to cognitive decline and dementia is uncertain. We aimed to determine the association between OH and the risk of developing dementia in the general population. METHODS AND FINDINGS: Between 4 October 1989 and 17 June 1993, we assessed OH in non-demented, stroke-free participants of the population-based Rotterdam Study...
