Abstract To evaluate functional capacity, mobility and balance in elderly patients with Alzheimer's Disease (AD), in its mild, moderate and severe forms, verifying the existence of correlation among these parameters. Eighty-eight elderly patients (81.79 ± 6.54 years) diagnosed with AD treated at an elderly care reference center in Taguatinga-DF were selected, and information was collected between November 2018 and March 2019. Data collection was initially made by filling in the evaluation form. Subsequently, two questionnaires were administered to caregivers (Clinical Dementia Rating-CDR and Disability Assessment fo...

This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons. Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. ...

We examined the association between shift work and the incidence of dementia in a cohort of female Danish nurses. METHODS: We linked Danish Nurse Cohort participants, who reported work schedules (day, evening, night, rotating shifts) in 1993 and/or 1999 and their duration in 2009, to Danish registers to obtain information on dementia hospitalizations and prescription medication until November 2018. RESULTS: Among 6048 nurses who reported work schedules in 1993 and 1999, nurses working night shifts ≥6 years had higher dementia incidence (hazard ratio: 2.43, 95% confidence interval: 1.39 to 4.23) than those workin...

Genome-wide association studies identified theBIN1 locus as a leading modulator of genetic risk in Alzheimer's disease (AD). One limitation in understandingBIN1's contribution to AD is its unknown function in the brain. AD-associatedBIN1 variants are generally noncoding and likely change expression. Here, we determined the effects of increasing expression of the major neuronal isoform of human BIN1 in cultured rat hippocampal neurons. Higher BIN1 induced network hyperexcitability on multielectrode arrays, increased frequency of synaptic transmission, and elevated calcium transients, indicating that increasing BIN1 drives g...

This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem. Studies in the past decade indicate that insufficient sun exposure may be responsible for 340,000 deaths in the United States and 480,000 deaths in Europe per year, and an increased incidence of breast cancer, colorectal cancer, hypertension, cardiovascular disease, metabolic syndrome, multiple sclerosis, Alzheimer’s disease, autism, asthma, type 1 diabetes and myopia. Vitamin D has long b...
