Factors associated with Alzheimer's disease prevalence and mortality in Brazil-An ecological study.

A few epidemiological studies are evaluating the prevalence and mortality rates of Alzheimer's disease, with no one using a nationwide sample of Brazilian elderlies. This study aims to calculate the prevalence of Alzheimer's disease and investigate possible associations with sociodemographic and lifestyle factors and the presence of diseases non-communicable, and the prevalence and mortality for all Brazilian state capitals. This is an ecological design study made with secondary public data provided by the Ministry of Health.

Effects of neurofeedback on major depressive disorder: a systematic review.

Background: Major depressive disorder is a difficult-to-treat psychological disorder. Approximately 30% of patients with major depressive disorder do not respond to conventional therapies; thus, the efficacy of alternative therapies for treating major depressive disorder, such as neurofeedback, a non-invasive neuromodulation method used in the treatment of psychiatric diseases, must be investigated.

Objective: We aimed to evaluate the efficacy of neurofeedback in minimizing and treating major depressive disorder and its application as a substitute to or an adjuvant with conventional therapies.

Confirmed Synergy Between the ɛ4 Allele of Apolipoprotein E and the Variant K of Butyrylcholinesterase as a Risk Factor for Alzheimer's Disease: A Systematic Review and Meta-Analysis.

Background: Alzheimer's disease (AD) has several risk factors. is the main one, and it has been suggested that there may be a synergy between it and as a risk factor.

Objective: To investigate the association between and as a risk factor for AD.

Hypothesis on ontogenesis and pathophysiology of Alzheimer's disease.

Alzheimer's disease is a neurodegenerative condition that causes changes in memory and cognition, in addition to behavioral disorders, and most commonly affects the elderly. Several studies in the literature have presented therapeutic measures in an attempt to interfere with the pathogenic mechanisms of the disease and to mitigate its clinical manifestations. Some factors, such as excitotoxicity, cholinergic dysfunctions, oxidative stress, tau protein hyperphosphorylation, changes in amyloid-beta peptide metabolism, herpes viruses, apolipoprotein E, glycogen synthase kinase 3, insulin resistance, and the endocannabinoid system seem to be related to pathophysiology of Alzheimer's disease.

Association between cognitive performance and sarcopenic obesity in older adults with Alzheimer's disease.

Unlabelled: Sarcopenic obesity (SO), the co-occurrence of sarcopenia and obesity, is associated with functional loss, frailty, and incapacity in older adults. Recently, SO was associated with reduced cognitive performance in adults. However, no SO studies have been done with older adults with Alzheimer's disease (AD).

Delta-Aminolevulinate dehydratase and glutathione peroxidase activity in Alzheimer's disease: a case-control study.

Alzheimer's disease (AD) is a neurodegenerative pathology that affects elderly people all over the world. Several studies have demonstrated that oxidative stress is an aggravating factor for AD development and progression. Therefore, this study aimed to evaluate the activity of two oxidative stress markers, glutathione peroxidase (GPx) and δ-aminolevulinate dehydratase (δ-ALA-D), as well as correlate them with blood metal levels and AD progression.

Nutritional and hematological factors associated with the progression of Alzheimer's disease: a cohort study.

Objective: We studied the users of the Specialized Drug Distribution Program of the public health network.

Methods: A prospective cohort examined the elderly at two intervals of three years and included 30 patients in phase I and 16 in phase II. The methodology was composed of home visits, anthropometric, nutritional and hematological evaluation.

Nutritional evaluation of geriatric patients with Alzheimer's disease in Southern Brazil: case-control study.

Introduction: elderly's malnutrition is linked, among other factors, to chronic-degenerative diseases, requiring an improvement in the clinical evaluation of nutritional status of this population. Studies have tried to find out new tools to assess aged-people nutritional status. One of most used scales to investigate nutritional status on geriatric patients is the Mini Nutritional Assessment (MNA).
