A 2024 Harvard study of more than 92,000 healthy men and women (average age 56) found that consuming about half a tablespoon of olive oil per day was associated with a 28% reduction in the risk for dementia-related death, regardless of diet quality.

As people age, cognitive skills wane and thinking and memory become more challenging, so they need to build up the brain's reserve. Embracing a new activity that requires thinking, learning, ongoing practice can be one of the best ways to improve cognitive skills like memory recall, problem solving, and processing speed.

Although less known and less understood than other types of dementia, Lewy body dementia is the second most common cause of neurodegenerative disease following Alzheimer's. How do its symptoms differ, who is at risk, and how is it diagnosed and treated?

A 2023 study suggests a blood test that looks for a specific biomarker may help identify people with Alzheimer's disease who may benefit from anti-amyloid therapy long before the disease is evident.

There is no cure for Alzheimer's, but medication can help manage the disease. Currently, the main FDA-approved drugs used to treat Alzheimer's are symptomatic drugs, which ease symptoms but don't address the cause of the disease. A new medication has been shown to slow the disease's progression and reverse some of its effects on memory among people with mild Alzheimer's.

In a 2024 study, men diagnosed with erectile dysfunction who took popular PDE5 inhibitors to treat their condition had a lower risk of developing Alzheimer's than men who didn't use medication.

A 2024 study found that dietary supplements of galantamine-which is used to treat Alzheimer's symptoms-had an inaccurate amount of the plant extract listed on the label, ranging from less than 2% to 110% of the labeled quantity.

Metformin, a medicine prescribed to treat type 2 diabetes, also has cardiovascular benefits and is used off-label to treat other conditions. Interest is growing in its potential to help lower risks for other serious health problems and even slow aspects of aging, but which of these benefits, if any, apply to people who do not have diabetes?

A 2023 study found that people who engaged in moderate or vigorous exercise an average of four days a week had more brain mass in regions associated with cognitive skills like memory and learning, compared with people who did not exercise.

A 2023 study suggests excessive TV-watching, defined as four or more hours a day, is associated with higher risk of developing brain-based disorders such as dementia, depression, and Parkinson's disease.
