A 2022 study of 78,000 healthy people (ages 40 to 79) who wore fitness trackers found that people who walked about 9,800 steps per day (about five miles) were 51% less likely to develop dementia, compared with people who didn't walk much at all.

Wintertime can pose challenges to cardiovascular health. Cold temperatures can cause arteries to narrow, which can leave people with heart disease vulnerable to angina or heart attacks, especially during physical exertion. Changes in sleep, eating, and exercise habits related to the season may also affect the heart. Crowded indoor gatherings also raise a person's risk for respiratory infections, which can exacerbate heart disease.

Having a dog or another pet appears to lower the risk of high blood pressure and improve blood pressure control. Pet ownership may foster positive feelings (such as decreased stress) and habits (such as daily walks) that may improve heart health. People who own dogs walk about 20 minutes more per day on average than those without dogs. Pets can help combat loneliness and social isolation, which have been linked to a higher risk of heart attack, stroke, or death from these causes.

A study found that people with mild cognitive impairment who did crossword puzzles regularly showed modest improvement in cognition and less brain shrinkage. Will doing crossword puzzles be helpful to people whose thinking and memory are normal?

The prescription drug Adderall has been in short supply for months. How widespread is this problem, and what are the consequences, and possible solutions, for adults who rely on this medication to manage ADHD?

A recent study found that older adults who took a multivitamin daily for three years had improved scores on tests of executive function, memory, and overall brain function, but the study wasn't large enough, long enough, or diverse enough to rely on its conclusions alone.

Mindfulness is the act of paying attention and focusing on the moment. Research has long shown mindfulness can help lower anxiety, but new studies suggest additional benefits. These include feeling less pain, making fewer mistakes, and being more resilient. Many people confuse meditation with mindfulness. Although there is some overlap, meditation is a practice that leads to being more mindful. Both meditation and mindfulness aim to help people stay present and nonjudgmental.

Each year, millions of couples face one partner's serious diagnosis with a condition such as cancer, heart or kidney failure, or neurological illness, among others. People can support their partners through a difficult diagnosis and treatment by keeping communication open, maintaining daily routines, becoming informed about the medical condition, attending doctor visits, adding assistive devices in their home, getting wills and other legal documents in order, and seeking and accepting help from others.

A 2022 study suggests that following certain healthy habits throughout life can create a "cognitive reserve" that may protect the brain from dementia. People in their 60s and 70s can still build up their reserve by pursuing a combination of brain-stimulating activities.

People who ate large amounts of ultra-processed foods had a greater risk of later developing dementia compared with people who ate little of these foods, according to a 2022 study. Researchers estimated that switching out even 10% of ultra-processed foods for healthier options might lower one's risk.
