The optimal amount of sleep for middle-aged and older adults is seven hours per night. Sleeping too little, or too much, was associated with poor cognitive performance and mental health, researchers say.
Researchers have developed a set of tests that can quantify cognitive changes in aging dogs and accurately detect canine cognitive dysfunction syndrome, a disorder with similar pathology and outcomes as Alzheimer's disease in humans. The findings show promise for both humans and dogs in understanding Alzheimer's progression.
Cognitive tests that rely on vision-dependent tasks may skew results for up to 25% of adults over 50 with undiagnosed visual problems such as AMD and cataracts. This may lead to a misdiagnosis of mild cognitive impairment in older adults.
Middle-aged people who consume blueberries every day may have a reduced risk of developing dementia, a new study reports.
Having three or more children was associated with an increased risk of cognitive decline later in life.
A preclinical drug that inhibits the kinase enzyme Cdk5 may have the potential to treat depression, brain injuries, and disorders associated with cognitive impairment.
Black adults who grew up socially disadvantaged and poor in the American South are more likely to experience cognitive decline as they age than white people with a similar background. Researchers report socioeconomic status, race, and childhood factors play a significant role in cognitive decline associated with aging.
Using CPAP to treat sleep apnea could help improve cognitive decline symptoms in older adults with mild cognitive impairment.
An older person's posture may give clues to hidden cognitive decline, a new study reports.
Global cognition can be estimated in older adults by automatically analyzing key drawing features while performing a drawing test using a tablet and digital pen.
Willingness in older people to give more money away appears to correlate with cognitive decline associated with dementia. The findings may explain why many older adults could be more prone to financial exploitation.
