Cognition is a concept used in different ways by different disciplines, but is generally accepted to mean the process of thought. For example, in psychology and cognitive science it refers to an information processing view of an individual's psychological functions.
Alcohol use disorders are known to adversely impact brain structure and function. Although recovery of brain morphology and function has been reported following abstinence from long-term alcohol use, some structural (e.g., brain area volumes and connections) and functional (e.g., cognitive) abnormalities due to long-term effects of AUDs may persist even after abstinence from alcohol.
Scientists have discovered the reason why patients who show brain markers for Alzheimer's never develop the condition.
New research published in the July edition of the Journal of Nutritional Biochemistry, has established a strong correlation between blood levels of omega-3s, especially docosahexaenoic acid (DHA), and better brain function in children two to six years old.
Older kidney disease patients who are sick enough to require the blood-filtering treatment known as dialysis are at high risk of dementia, including Alzheimer's disease, according to a study led by scientists at Johns Hopkins Bloomberg School of Public Health.
About 50 percent of people who reach the age of 85 will develop Alzheimer's disease. Most will die within about five years of exhibiting the hallmark symptoms of the disease - severe memory loss and a precipitous decline in cognitive function.
A new study using data from over 5,000 individuals has found that a measure of belly fat (waist:hip ratio) was associated with reduced cognitive function in older Irish adults (>60 years of age).
Glenn Wylie, DPhil, and Jorge Serrador, PhD, have won an award from the Rutgers Brain Health Institute. The grant funds a collaborative study between the Department of Pharmacology, Physiology, and Neuroscience at Rutgers New Jersey Medical School and Kessler Foundation.
Women's brains are much more vulnerable than men's to injury from repeated soccer heading, according to a new study by researchers at Albert Einstein College of Medicine, part of Montefiore.
Inhaled vaporized cannabis does not appear to improve or worsen exercise performance and activity-related breathlessness in patients with advanced chronic obstructive pulmonary disease, according to a randomized controlled trial published online in the Annals of the American Thoracic Society.
Inflammation is part of the body's natural healing process. But when it becomes chronic, inflammation can lead to cancer, Alzheimer's disease and other conditions.
Significant reductions in the risk of mild cognitive impairment (MCI), and the combination of MCI and dementia, have been shown for the first time through aggressive lowering of systolic blood pressure in new research results from the federally-funded SPRINT MIND Study reported at the Alzheimer's Association International Conference 2018 in Chicago.
Reduced levels of plasmalogens-;a class of lipids created in the liver that are integral to cell membranes in the brain-;are associated with an increased risk of Alzheimer's Disease, according to new research presented this week at the Alzheimer's Association International Conference 2018 by Mitchel A. Kling, MD, an associate professor of Psychiatry in the Perelman School of Medicine at the University of Pennsylvania and the Veterans Affairs Medical Center.
Researchers at King's College London have found that muscle fitness as measured by power in the legs is strongly associated with an improved rate of ageing in the brain.
In adults over 70, exposure to general anesthesia and surgery is associated with a subtle decline in memory and thinking skills, according to new Mayo Clinic research.
Older Asian-American immigrants are healthier and happier if they are socially active, connected to their families and communities and are able to maintain their cultural values while adapting to western culture, according to a new Rutgers study.
In a first of its kind randomized trial, researchers from the UCI School of Medicine found therapy dogs to be effective in reducing the symptoms of attention deficit/hyperactivity disorder in children.
Anyone lost in a desert hallucinating mirages knows that extreme dehydration discombobulates the mind. But just two hours of vigorous yard work in the summer sun without drinking fluids could be enough to blunt concentration, according to a new study.
An updated systematic review from Harvard University examines 25 years of evidence for the role of walnut consumption on cardiovascular risk factors, including cholesterol, triglycerides, blood pressure, and weight.
A new study has found that "skinny fat" - the combination of low muscle mass and strength in the context of high fat mass - may be an important predictor of cognitive performance in older adults.
Researchers at Johns Hopkins have added to evidence that rising and chronic inflammation as measured by a biomarker in the blood in middle and late age are linked to visible structural changes in the brains of people with poor cognition and dementia.
