Older adults with more natural teeth are better able to carry out simple everyday tasks like cooking and cleaning compared to those who have lost their teeth, a new study reports. Researchers found a causal link between tooth loss and functional capacity in older adults. Tooth loss was also associated with a decline in social activity.
Adults over 80 who maintained a healthy lifestyle, including exercise and diet, had a lower risk of cognitive decline, even if they had genetic risk factors for dementia.
When listening to a phrase over and over, the words often begin to sound like a song. Researchers found this speech-to-song illusion does not decrease with age.
Making small lifestyle changes, such as improving diet, exercising, enjoying social activities, and reducing blood pressure, can reduce the risk of developing dementia in older people with certain risk factors.
People diagnosed with Alzheimer's or mild cognitive impairment had weaker gamma wave activation in their brains than their peers without the neurodegenerative disorders.
A new deep neural network can accurately predict a healthy person's brain age based on EEG data collected from a sleep study.
Researchers have identified three biomarkers in blood samples that confirm the link between exercise and improved cognitive function in older adults.
Depleting the protein ADORA2B from the blood of mice led to faster cognitive decline, decreased auditory processing, and increased brain inflammation.
