Hearing loss has a profound impact on older people, as it can lead to anxiety, restricted activity, and perhaps even cognitive decline and dementia. Research has examined associations of hearing loss with outdoor activity limitations, psychological distress, and memory loss…

The risk factors for stroke and dementia are the same, and a growing body of evidence demonstrates that preventing stroke can also prevent some dementias. Now, a group of experts is calling on the global community to come together to…

Apathy is the most common neuropsychiatric symptom of dementia, with a bigger impact on function than memory loss -- yet it is under-researched and often forgotten in care.

The abnormal accumulation of proteins in the brain is a biological marker for Alzheimer's disease, but the ways in which these proteins spread may help explain why the prevalence of Alzheimer's is higher in women than in men.

A new study has found that mentally stimulating activities like using a computer, playing games, crafting and participating in social activities are linked to a lower risk or delay of age-related memory loss called mild cognitive impairment, and that the…

There are currently no drugs that stop or inhibit Alzheimer's disease. Despite drug trials showing plaque reduction in the brain, the patients' cognitive function did not improve. Would the results be different if it were possible to design studies that…

A molecule known as VPS35 detects and removes defective proteins from neurons. Researchers show for the first time that VPS35 clears the brain of a potentially harmful protein called tau, which otherwise accumulates and contributes to neurodegenerative disorders, including Alzheimer's…

The risk of developing Alzheimer's disease increases with age. Medical researchers have uncovered a possible cause for this connection: Certain molecules involved in the disease, termed tau-proteins, spread more easily in the aging brain.

It happens unexpectedly: a person long thought lost to the ravages of dementia, unable to recall the events of their lives or even recognize those closest to them, will suddenly wake up and exhibit surprisingly normal behavior, only to pass…

Gentle sound stimulation played during deep sleep enhanced deep sleep for people with mild cognitive impairment, who are at risk for Alzheimer's disease, a new study found. Those whose brains responded the most robustly to the sound stimulation showed an…

Scientists have discovered a pathway that functions like a car wash to prevent the buildup of a toxic protein associated with Alzheimer's disease.

PET brain scans of healthy older adults show that those reporting lower sleep quality through their 50s and 60s have higher levels of tau protein, a risk factor for Alzheimer's disease. Previous studies link poor sleep to beta-amyloid tangles also,…

Scientists call for randomized deprescribing trials to address anticholinergic drug use as a potentially modifiable and reversible risk factor for dementia, a growing public health issue.

Researchers have found that immune cells that typically protect neurons from damage may be the link between early and late brain changes in Alzheimer's disease. Breaking that link could lead to new approaches to delay or prevent the disease.
