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.
A new study performed in the Netherlands has linked exposure to residential air pollution during fetal life with brain abnormalities that may contribute to impaired cognitive function in school-age children. The study, published in Biological Psychiatry, reports that the air pollution levels related to brain alterations were below those considered to be safe.
Sanford Burnham Prebys Medical Research Institute researchers have published two new studies in Neuron that describe how TREM2, a receptor found on immune cells in the brain, interacts with toxic amyloid beta proteins to restore neurological function.
People aged 85 and older whose total cholesterol had increased from their levels at midlife had a reduced risk for marked cognitive decline, compared with those a decade younger whose cholesterol was similarly elevated, Mount Sinai researchers report in a new study.
A new study reveals that hemodialysis may reduce blood flow to the brain in older patients being treated for kidney failure.
When we create a memory, a pattern of connections forms between neurons in the brain. New work from UC Davis shows how these connections can be strengthened or weakened at a molecular level. The study is published Feb. 27 in the journal Cell Reports.
Children with chronic kidney disease (CKD) may have lower intellectual functioning compared with the general population, with mild deficits across academic skills, executive function, and visual and verbal memory.
Primary schoolchildren who have been raised in homes surrounded by more greenspace tend to present with larger volumes of white and grey matter in certain areas of the brain.
Allogeneic blood or marrow transplantation recipients are at a significantly higher risk of cognitive impairment in the years post-transplantation, according to a study published in Journal of Clinical Oncology.
A new study in mice has made a possible breakthrough in Alzheimer’s research. The team of researchers at the Cleveland Clinic has noted that deleting a single enzyme can reverse the deposition of harmful plaques in the brains of patients with Alzheimer’s disease. This could improve cognitive functions as demonstrated in lab mice. The study appeared this week in the latest issue of the Journal of Experimental Medicine.
A team of researchers from the Cleveland Clinic Lerner Research Institute have found that gradually depleting an enzyme called BACE1 completely reverses the formation of amyloid plaques in the brains of mice with Alzheimer's disease, thereby improving the animals' cognitive function.
Higher levels of lifestyle physical activity – such as house cleaning, walking a dog and gardening, as well as exercise – are associated with more gray matter in the brains of older adults, according to a study by researchers at Rush University Medical Center.
Want to live a long and healthy life? Of course. Well, that's not going to just happen. It'll take some effort – especially if you're already 65 or older.
The common food preservative sodium benzoate improves symptoms in clozapine-resistant schizophrenia patients, according to a new study published in Biological Psychiatry.
Breathing too much carbon dioxide can be deadly, but it can happen during sleep if a particular sleeping position causes an obstructed airway or because of a medical condition like sleep apnea.
In a breakthrough study, scientists at the Rockefeller University have observed the effects of Huntington’s disease in neurons as early as conception.
It is a parent's nightmare: a child is born apparently healthy, then stops meeting developmental milestones at one year old. Her verbal and motor skills vanish, and irregular breathing, seizures, and a host of other problems appear.
Enhanced lifestyle counselling could prevent cognitive decline in people who are genetically predisposed to develop Alzheimer’s disease, finds new study.
Alzheimer's disease (AD) is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults.
A diet created by researchers at Rush University Medical Center may help substantially slow cognitive decline in stroke survivors, according to preliminary research presented on Jan. 25, at the American Stroke Association's International Stroke Conference 2018 in Los Angeles.
Mice with the genetic defect that causes Fragile X syndrome (FXS) learn and remember normally, but show an inability to learn new information that contradicts what they initially learned, shows a new study by a team of neuroscientists.
