OBJECTIVE: Alzheimer's Disease (AD) is a major neurological disorder marked by an amyloid-beta plaque and neurofibrillary tau-tangle depositions in the brain. Cognitive dysfunction is the key manifestation of AD. In this study, we conducted an umbrella review of meta-analyses on the risk factors and therapeutics targeting cognitive impairment and AD. MATERIALS AND METHODS: We searched PubMed from January 2000-August, 2016, and screened systematic reviews and meta-analyses of studies that examined the effects of cholinesterase inhibitors in AD patients...

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...

AIMS: The sporadic and late-onset form of Alzheimer's disease (AD) constitutes the most common form of dementia. This non-familiar form could be a consequence of metabolic syndrome, characterized by obesity and the development of a brain-specific insulin resistance known as type III diabetes. This work demonstrates the development of a significant AD-like neuropathology due to these metabolic alterations. METHODS: C57BL/6J mice strain were divided into two groups, one fed with a diet rich in palmitic acid (high-fat diet, HFD) since their weaning until 16 months of age, and another group used as a control with a regular diet...

Olfactory dysfunction is associated with normal aging, multiple neurodegenerative disorders, including Parkinson's disease, Lewy body disease and Alzheimer's disease, and other diseases such as diabetes, sleep apnea and the autoimmune disease myasthenia gravis. The wide spectrum of neurodegenerative disorders associated with olfactory dysfunction suggests different, potentially overlapping, underlying pathophysiologies. Studying olfactory dysfunction in presymptomatic carriers of mutations known to cause familial parkinsonism provides unique opportunities to understand the role of genetic factors, delineate the salient characteristics of the onset of olfactory dysfunction, and understand when it starts relative to motor and cognitive symptoms...

Invasive and non-invasive vagus nerve stimulation (VNS) is a promising add-on treatment for treatment-refractory depression, but is also increasingly evaluated for its application in other psychiatric disorders, such as dementia, schizophrenia, somatoform disorder, and others. We performed a systematic review aiming to give a detailed overview of the available evidence of the efficacy of VNS for the treatment of psychiatric disorders. Data derived from animal models, experimental trials without health-related outcomes, case reports, single-session studies, and reviews were excluded...

BACKGROUND & AIMS: Older diabetic people are at risk of cognitive decline. Vitamin B12 deficiency in older people is associated with cognitive impairment and Alzheimer's disease. Vitamin B12 deficiency may therefore contribute to cognitive decline in older diabetic people. We therefore performed a randomized placebo-controlled trial of vitamin B12 supplementation to prevent cognitive decline in older diabetic people with mild vitamin B12 deficiency. METHODS: 271 diabetic non-demented outpatients aged 70 years or older with plasma vitamin B12 150-300 pmol/L in outpatient clinics were randomly assigned to take either methylcobalamin 1000 μg or two similar looking placebo tablets once daily for 27 months...

BACKGROUND: Diabetes mellitus is a risk factor for cognitive changes, but assessment for cognitive disorders in this population is performed infrequently. This study examines the frequency of cognitive disorders and patterns of deficit in patients enrolled in a specialized clinic for diabetes. METHODS: A cross-sectional study was conducted to assess cognition in Mount Sinai Diabetes Center patients. Thirty eligible subjects age 50 or older were assessed and compared with non-diabetic cognitively normal control subjects, as well as non-diabetic subjects with Mild Cognitive Impairment (MCI)...

The role of insulin-like growth factor I (IGF-I) and its receptor (IGF-IR) in brain pathology is still unclear. Thus, either reduction of IGF-IR or treatment with IGF-I, two apparently opposite actions, has proven beneficial in brain diseases such as Alzheimer´s dementia (AD). A possible explanation of this discrepancy is that IGF-I down-regulates brain IGF-IR levels, as previously seen in a mouse AD model. We now explored whether under normal conditions IGF-I modulates its receptor. We first observed that in vitro, IGF-I reduced IGF-IR mRNA levels in all types of brain cells including neurons, astrocytes, microglia, endothelial cells, and oligodendrocytes...

Alzheimer´s disease, a progressive and degenerative disorder of the brain, is the most common cause of dementia among the elderly. To face its multifactorial nature, the use of single compounds that can simultaneously modulate different targets involved in the neurodegenerative cascade has emerged as an interesting therapeutic approach. In that context, we investigated the ability of uleine, the major indole alkaloid purified from the stem barks of the Brazilian medicinal plant Himatanthus lancifolius, to interact with crucial Alzheimer´s disease disruptive targets...

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...

Type 2 diabetes (T2D) is a highly concerning public health problem of the twenty-first century. Currently, it is estimated that T2D affects 422 million people worldwide with a rapidly increasing prevalence. During the past two decades, T2D has been widely shown to have a major impact in the brain. This, together with the cognitive decline and increased risk for dementia upon T2D, may arise from the complex interaction between normal brain aging and central insulin signaling dysfunction. Among the several features shared between T2D and some neurodegenerative disorders (e...

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...

INTRODUCTION: MCP-1 and eotaxin-1 are encoded on chromosome 17 and have been shown to reduce hippocampal neurogenesis in mice. We investigated whether these chemokines selectively associate with memory in individuals with mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia. METHODS: MCP-1 and eotaxin-1 were assayed in controls, MCI, and AD dementia patients with varying phenotypes (n = 171). A subset of 55 individuals had magnetic resonance imaging (MRI) scans available...
