BACKGROUND & AIMS: Vitamin D deficiency has been identified as a global problem. Approximately 14% of the world population has inadequate vitamin D levels. This vitamin has been usually associated with bone disorders such as rickets, osteomalacia, and osteoporosis. However, these disorders present only a small part of all the disturbances which can be induced by its deficiency. Low serum vitamin D is associated with development of cardiovascular diseases, hypertension, neurodegenerative diseases, diabetes mellitus, metabolic syndrome and even cancer...

Although regular physical activity is known to benefit health of aging populations, there are still many factors, which regulate exercise-induced adaptive changes. Among many vitamin D and myokines are under consideration. We, therefore, evaluated the influence of a single session of and regular Nordic Walking (NW) training combined with vitamin D supplementation on cognitive functions and muscle strength and some elements of the amino-acid profile. Thirty-five healthy elderly women (68 ± 5 years old) from health promotion programmes took part in the study...

BACKGROUND: Older adults with hypovitaminosis D report more often subjective cognitive complaints, especially with regards to memory. This raises prospects that vitamin D may improve older adults' subjective experience of memory disorders. OBJECTIVE: To determine among older community-dwellers whether higher serum 25-hydroxyvitamin D (25OHD) concentrations were associated with fewer memory complaints, while considering the different subtypes of memory complaints...

BACKGROUND: Many extremely preterm infants have low vitamin D concentrations at birth, but early childhood outcomes after vitamin D supplementation have not been reported. OBJECTIVE: To determine a dose-response relationship between increasing doses of enteral vitamin D in the first 28 days after birth and cognitive scores at 2 years of age. METHODS: In this phase II double-blind dose-response randomized trial, infants with gestational ages between 23 and 27 weeks were randomly assigned to receive placebo or a vitamin D dose of 200 or 800 IU/day from day 1 of enteral feeding to postnatal day 28...

Premenstrual syndrome (PMS) consists of repetitious physical and psychological symptoms. The symptoms occur during the luteal phase of the menstrual period and cease when the menstrual period starts. This study included pre-test and post-test experiments between a control group and a test group. The statistical population involved 40 females, chosen based on multistage cluster sampling. The participants were then divided into four groups to undergo treatment with calcium supplement plus vitamin D together with cognitive behavioral therapy (CBT), and were screened with the Premenstrual Syndrome Screening Test (PSST)...

Some dietary supplements are recommended to athletes based on data that supports improved exercise performance. Other dietary supplements are not ergogenic per se, but may improve health, adaptation to exercise, or recovery from injury, and so could help athletes to train and/or compete more effectively. In this review, we describe several dietary supplements that may improve health, exercise adaptation, or recovery. Creatine monohydrate may improve: recovery from and adaptation to intense training, recovery from periods of injury with extreme inactivity, cognitive processing, and reduce severity of or enhance recovery from mild traumatic brain injury (mTBI)...

The impairment of hippocampal neurogenesis at the early stages of Alzheimer's disease (AD) is believed to support early cognitive decline. Converging studies sustain the idea that vitamin D might be linked to the pathophysiology of AD and to hippocampal neurogenesis. Nothing being known about the effects of vitamin D on hippocampal neurogenesis in AD, we assessed them in a mouse model of AD. In a previous study, we observed that dietary vitamin D supplementation in female AD-like mice reduced cognitive decline only when delivered during the symptomatic phase...

Globally populations are ageing. By 2050, it is estimated that there will be two billion people aged 60 years or over, of which 131 million are projected to be affected by dementia, while depression is predicted to be the second leading cause of disability worldwide by 2020. Preventing or delaying the onset of these disorders should therefore be a public health priority. There is some evidence linking certain dietary patterns, particularly the Mediterranean diet, with a reduced risk of dementia and depression...

This study focused on the hypothesis that cognitive decline in aged dogs could be attenuated by dietary supplementation with a nutrient blend consisting of antioxidants, B vitamins, fish oil and l-arginine, referred to hereafter as the Brain Protection Blend (BPB). Baseline cognitive assessment before the start of treatment was used to establish cognitively equivalent control (10·464+2·33 kg) and treatment (12·118+3·386 kg) groups of aged dogs between 9·1 and 11·5 years of age and with body condition score of 5...

Nutraceuticals have generated interest as a way to mitigate the cognitive decline in older adults. The aim of this systematic review was to determine the evidence for these claims from the scientific literature in randomised, double-blinded, controlled trials (duration: ≥1 year; participants: n≥100; age(mean): ≥65 years). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched four electronic databases (PubMed, Scopus, CINAHL and Web of Science) and identified twenty-five studies published between the 15·June·2006 and 14·June·2016...

Klotho is an aging-related protein associated with hippocampal cognitive performance in mammals. Klotho regulates progenitor cell proliferation in non-neuronal tissues, but its role in adult hippocampal neurogenesis (AHN) has not been explored. Klotho expression in the adult mouse hippocampus was examined by immunofluorescence and PCR. AHN was evaluated in the hippocampus of klotho knock-out mice (KO), klotho KO/vitamin D-receptor mutant mice, and in a model of local klotho hippocampal knockdown. The recombinant Klotho effect on proliferation was measured in mouse-derived hippocampal neural progenitor cells...

BACKGROUND: Accumulating evidence suggest that dietary factors are associated with Alzheimer's disease, and brain and cognitive health. It is unclear whether inflammation explains this association. OBJECTIVE: To examine whether an inflammation-related nutrient pattern (INP) was associated with neuroimaging and cognitive measures of brain health. METHOD: The current cross-sectional study included 330 non-demented elderly (mean age 79 years at MRI scan) participants in a multi-ethnic, community-based cohort study who had information on nutritional intakes (estimated from food frequency questionnaire), circulating C-reactive protein and interleukin-6 (measured by ELISA), MRI scans, and cognition...

Introduction: Criteria for mild cognitive impairment (MCI) used in many clinical trials are susceptible to "false-positive (FP)" errors that can be avoided by an actuarial psychometric approach. Methods: Cluster analysis was applied to baseline neuropsychological test data from 756 MCI participants in the Alzheimer's Disease Cooperative Study donepezil trial. Treatment groups were compared after FP MCI cases were removed. Results: Cluster analyses revealed three groups: "single-domain amnestic MCI" (31%), "multi-domain amnestic MCI" (39%), and "FP MCI" (30%)...

BACKGROUND: Mild cognitive impairment (MCI) has an increased rate of progression to dementia. Alterations of some metabolic factors, such as deficiency of vitamin D, are a risk factor for cognitive deterioration. Vitamin D is involved in the clearance of β-amyloid (Aβ) from the brain. We have reported that lymphocytes from Alzheimer's disease (AD) patients have an increased susceptibility to oxidative death by H2O2 exposure, but currently it is unknown if this characteristic is modifiable in vivo...
