Researchers from HSE University and York University have become the first to analyze the results of 82 functional neuroimaging studies on working memory mechanisms in different adult age groups. The meta-analyses showed that across studies the agreement of various areas of the prefrontal cortex decreases with aging, suggesting reorganization of brain function during healthy aging. The results have been published in NeuroImage journal.
The federal right-to-try law's effect on the FDA, the gamification of science, how the Conscience and Religious Freedom Division is changing health care, and more in the latest issue.
A new University of Maryland School of Public Health study of healthy older adults shows that just one session of exercise increased activation in the brain circuits associated with memory -- including the hippocampus -- which shrinks with age and is the brain region attacked first in Alzheimer's disease.
Medicare-covered stroke patients receive vastly different amounts of physical and occupational therapy during hospital stays despite evidence that such care is strongly associated with positive health outcomes, a new study by Brown University researchers found.
A paper by Columbia Mailman School's John Rowe, M.D., Julius Richmond Professor of Health Policy and Aging, in the journal Health Affairs outlines the challenges we face as the US becomes an 'aging society.' This transformation has major implications for our core institutions which were not designed to support this changing population distribution.
A specially designed mobile phone game can detect people at risk of Alzheimer's -- according to new research from the University of East Anglia. Researchers studied gaming data from an app called Sea Hero Quest, which has been downloaded and played by more than 4.3 million people worldwide.
Close to 20% of elderly adults who have suffered a heart attack will be readmitted to the hospital within 30 days. Performance on a simple mobility test is the best predictor of whether an elderly heart attack patient will be readmitted, a Yale-led study reports.
Research suggests that having a happy spouse leads to a longer marriage, and now study results show that it's associated with a longer life, too. The study was published in Psychological Science, a journal of the Association for Psychological Science.
'Is amyloid precursor protein the mastermind behind Alzheimer's or is it just an accomplice?' Researchers devised a multi-functional reporter for amyloid precursor protein and tracked its localization and mobility, noticing a strange association between the protein and cholesterol that resides in the cell membrane of synapses. With cholesterol's broad involvement in almost all aspects of neurons' life, they propose a new theory on the amyloid precursor protein connection in AD, especially in the surface of those tiny synapses, which triggers neurodegeneration.
Study found more than half of older adults with end-stage kidney disease died within a year of starting dialysis. Nearly one in four older dialysis patients (23%) succumbed to the disease within a month of starting treatment. Analysis reveals markedly higher death rates than previous reports of dialysis outcomes among older patients. Findings can help patients and clinicians make better-informed decisions to determine optimal course of treatment.
