Noting that the prescription of proton pump inhibitors is on the rise among middle-aged and older adults, a team of researchers designed a new study to examine PPIs and the risk of dementia, mild cognitive impairment, and Alzheimer's disease. They published their study in the Journal of the American Geriatrics Society.

"Preacher" star Graham McTavish on how season 2 raises the stakes of the demented AMC and Amazon action series.

Cognitive training, blood pressure management for people with hypertension, and increased physical activity all show modest but inconclusive evidence that they can help prevent cognitive decline and dementia, but there is insufficient evidence to support a public health campaign encouraging their adoption, says a new report.

Parkinson's disease is commonly thought of as a movement disorder, but after years of living with the disease, approximately 25 percent of patients also experience deficits in cognition that impair function. A newly developed research tool may help predict a patient's risk for developing dementia and could enable clinical trials aimed at finding treatments to prevent the cognitive effects of the disease.

The Mediterranean diet is associated with a variety of health benefits, including a lower incidence of dementia. Now, researchers have identified a specific ingredient that protects against cognitive decline: extra-virgin olive oil. In a new study, the researchers show that consumption of extra-virgin olive oil protects memory and learning ability and reduces the formation of amyloid-beta plaques and neurofibrillary tangles in the brain -- classic markers of Alzheimer's disease.
