Studies indicate the involvement of brain-derived neurotrophic factor (BDNF) in the pathogenesis of Alzheimer's disease (AD). Decreased BDNF levels may constitute a lack of trophic support and contribute to cognitive impairment in AD. The benefits of acute and chronic physical exercise on BDNF levels are well-documented in humans, however, exercise effects(More)
Elderly individuals with AD are more susceptible to falls, which might be associated with decrements in their executive functions and balance, among other things. We aimed to analyze the effects of a program of dual task physical activity on falls, executive functions and balance of elderly individuals with AD. We studied 21 elderly with probable AD,(More)
The decline in frontal cognitive functions contributes to alterations of gait and increases the risk of falls in patients with dementia, a category which included Alzheimer's disease (AD). The objective of the present study was to compare the gait parameters and the risk of falls among patients at different stages of AD, and to relate these variables with(More)
Some studies have shown differences in specific cognitive ability domains between the sexes at 60 years-of-age. However is important to analyze whether the rate of cognitive decline is also similar between the sexes after this age. The present study examined previously published literature to investigate whether cognitive decline is distinct between men and(More)
BACKGROUND Physical exercise influences homocysteine (Hcy) concentrations, cognitive function and the metabolic profile. The purpose of this study was to investigate the influence of regular physical exercise on Hcy levels, the metabolic profile and cognitive function in healthy elderly males before and after an endurance exercise program. METHODS(More)
BACKGROUND The lipid fraction of cell membranes consists of polyunsaturated fatty acids (PUFAS), and chronic alcohol use alters it, modifying its permeability, what might contribute for the dysfunctional metabolism observed in the central nervous system of alcohol dependent patients. Therefore, the supplementation of PUFAS can be an important adjuvant in(More)
BACKGROUND Inadequate oxygenation may cause lesions and brain atrophy during aging. Studies show a positive association between pulmonary function and the cognitive performance of individuals from middle age on. OBJECTIVE To investigate the effect of aerobic physical exercises and respiratory training on the blood oxygenation, pulmonary functions, and(More)
UNLABELLED Since attention deficit/hyperactivity disorder (ADHD) presents high prevalence among children, science has been researching alternative forms of treatment that do not involve medication. OBJECTIVE To evaluate the effects of polyunsaturated fatty acids (PUFAs) on attention deficit/hyperactivity disorder. METHODS We reviewed the articles(More)
OBJECTIVE Since blood viscosity (BV) is one of the most important factors determining blood flow, this study aimed to investigate the possible correlation between increased blood viscosity and reduction of regional cerebral blood flow (rCBF) in healthy ageing. METHODS Male subjects were distributed in two groups: "young", aged 20-30 (27 volunteers), or(More)
