Some blood pressure drugs may lower dementia risk

Taking antihypertension drugs to lower blood pressure that also stimulate type 2 and 4 angiotensin II receptors in the brain may offer protection against Alzheimer’s disease and other dementias.

How much sleep keeps cognitive decline at bay?

Sleeping six hours or less is associated with impaired cognition, mostly in memory, as well as an increase in the protein that can form brain plaque. Sleeping nine hours or more is also linked to cognitive problems, especially in decision making.

Exposure to traffic noise linked to higher dementia risk

A decade or more of high exposure to traffic noise may increase dementia risk.

Working out your brain

Cardio exercise has been convincingly linked to less cognitive decline and may even improve cognitive functioning. Research suggests it can strengthen the heart, promote arterial health, improve blood flow to the brain, fight inflammation, and increase key chemicals that promote new brain cell growth. The type of exercise does not matter, but cardio that is both physically challenging and offers mental stimulation is ideal.

Too much coffee may raise dementia risk

Drinking coffee daily can provide a welcomed mental jolt for many people. But new research suggests regular coffee drinkers should stop at five or six cups per day, as drinking more may increase their risk for dementia.

Can friends who listen help protect your memory and thinking skills?

A study published online Aug. 16, 2021, by JAMA Network Open suggests that older adults with good listeners in their lives have better thinking skills—despite decreases in brain volume—compared with people who don’t have good listeners in their lives.

Mentally challenging jobs may reduce the risk of dementia

People with jobs that are more mentally stimulating may have a lower risk of dementia later in life.

Do statins increase the risk of dementia?

A study published June 29, 2021, by the Journal of the American College of Cardiology (JACC) found no link between statin use and a higher incidence of dementia in adults ages 65 and older, but other studies have described possible cognitive changes related to statin use. Experts say that the benefits of taking a statin for people who have risk factors for cardiovascular disease generally far outweigh the risks. Statin use can reduce the risk of a heart attack or stroke by 25% to 30%.

Can medication help us combat Alzheimer’s disease?

Aducanumab is a newly approved drug for Alzheimer’s disease with the potential to reduce amyloid-beta plaque buildup in the brain. There are other medications being studied to see if they can reduce amyloid-beta, such as a monoclonal antibody that targets amyloid-beta before it forms plaques, and a monoclonal antibody that takes aim at plaque that has already formed. Other experimental approaches try to prevent tau tangles in brain cells, reduce brain inflammation, or reduce the amount of amyloid-beta that is produced.
