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.

Switching to a salt substitute may reduce stroke risk

Swapping regular table salt (sodium chloride) with a salt substitute containing some potassium chloride may lower the risk of strokes and related heart problems.

Helpful gadgets for a fuzzy memory

Many gadgets help support memory. Some—such as calendars, voice recorders, and talking motion-activated sensors—provide basic reminders that can be used to help someone remember appointments, lists, and more. Other tools, such as key hooks and mini shelves, support memory by establishing a reliable storage spot for everyday objects such as keys and eyeglasses. Automatic pill dispensers and pill alarms can help people manage a medication regimen. Wireless trackers can help people find objects when they’re misplaced. Smartphones have many memory-support tools, such as calendars, notepads, voice recorders, and alarms.

Harvard finds flavonoids linked to sharper thinking and memory

People with the highest daily flavonoid intakes were 19% less likely to report trouble with memory and thinking, compared with people who had the lowest daily flavonoid intakes, according to a Harvard study published online July 28, 2021, by Neurology.

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.

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.

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.

Diets rich in flavonoids linked to better brain health

Diets rich in plant chemicals called flavonoids may help protect the brain.

COVID-19 diagnosis raises risk of heart attack, stroke

A Swedish study suggests that risk of a heart attack or stroke at least triples in the week following a COVID-19 diagnosis.

The danger of a "silent" heart attack

So-called silent heart attacks (marked by unexplained weakness, fatigue, shortness of breath, or nausea) often go unrecognized. But they may be almost as concerning as regular heart attacks and have been linked to a higher risk of stroke. Some of this heightened stroke risk stems from shared risk factors, including high blood pressure, diabetes, and elevated cholesterol levels. But heart attacks can also damage the heart’s lower chambers. This may prevent the heart from contracting normally, which can lead to formation of a clot that then travels to the brain, causing a stroke.
