Investigating memory loss

Sudden memory lapses could be natural aspects of aging or early signs of mild cognitive impairment (MCI). With MCI, memory loss is noticeable but usually does not impede the ability to carry out daily functions. A screening test from a doctor or more advanced testing (such as brain MRI or PET scans) from a neurologist can help identify potential cognitive problems so people can seek appropriate treatment.

Fluctuating sleep times might boost your heart attack and stroke risk

A 2024 study involving more than 72,000 healthy people ages 40 to 79 found that those whose sleep and wake times fluctuated most had a 26% higher risk of having a heart attack, stroke, or similar problem, compared with those whose sleep patterns fluctuated least.

Mediterranean diets lower blood sugar levels and slow brain shrinkage

Eating a traditional Mediterranean diet or green Mediterranean diet, which emphasizes more foods high in plant foods, including green tea and duckweed, may help reduce brain shrinkage, a 2024 study suggests.

Getting fiber while avoiding gluten

A gluten-free diet (which omits wheat, rye, and barley) may be low in fiber, a nutrient that's important for cardiovascular health. People who avoid gluten should try to include gluten-free grains and seeds in their menus, such as amaranth, buckwheat, millet, sorghum, teff, and quinoa. Carrots, celery, kale, and kiwis contain mostly insoluble fiber, which helps you feel full and encourages regular bowel movements. Beans, nuts, seeds, and fruits (such as berries, apples, pears, and citrus fruits) are good sources of soluble fiber, which helps lower cholesterol and blood sugar.

These drugs might be best to relieve migraine pain

A 2024 analysis of 137 studies involving almost 90,000 people found that older drugs called triptans are more effective at stopping migraine pain in a moment of agony, compared with newer medications such as ditans and gepants.

Can a "weekend warrior" exercise regimen protect your brain?

A 2024 study of more than 10,000 dementia-free people found that fitting the recommended amount of weekly exercise into one or two sessions was associated with a similar reduction in dementia risk as exercising throughout the work week.

Gum disease and heart health: Probing the link

About two-thirds of people over 65 have periodontal disease, which is linked to a higher risk of heart disease. Shared risk factors such as smoking and an unhealthy diet may explain the association, but bacteria and inflammation could be a common thread. The bacteria responsible for periodontal disease can travel to blood vessels throughout the body and have been found in the fatty debris (atherosclerosis) that clogs arteries located far from the mouth-and in blood clots from people who have experienced heart attacks.
