People who devote time to helping others are often happier than those who don't. Serving others also helps brain health by increasing social connections, which can protect against loneliness and depression, and improving executive function skills like planning, attention, and remembering tasks. Common ways to help others include volunteering, mentoring, random acts of kindness, and seeing life from another person's perspective.

Lower temperatures, high wind speed, atmospheric pressure, high precipitation, and high degrees of pollution may raise the risk of being hospitalized for serious heart-related conditions. Modeling these factors may help forecast future heart problems.

Memory loss is a pervasive worry. Dementia will affect an estimated nine million Americans by 2030 and 12 million by 2040. A 2023 study suggests six healthy lifestyle factors can significantly slow memory decline: eating a healthy diet, exercising regularly, not smoking, not drinking alcohol, being socially active, and engaging in brain-challenging activities. Another 2023 study suggests regular Internet use may be linked to a lower risk of dementia.

Naps can be healthy for adults who need to catch up on sleep or work odd hours, but they can also make it more difficult to sleep at night and be a sign of a sleep disorder. Naps should be short and limited to the early afternoon to prevent them from interfering with nighttime sleep. People who have the urge to nap daily should consider whether they need to improve their nighttime sleep habits.

Accelerated cognitive decline may be more common after a heart attack, probably because the same factors that lead to narrowed heart arteries (the root cause of most heart attacks) can also cause tiny, silent strokes. An accumulation of these strokes shows up as bright areas (called white matter lesions) on an MRI scan. These lesions are markers of typical cognitive changes that occur with age. But people who have heart attacks likely have more white matter lesions and experience even greater cognitive decline.

A 2023 study suggests that eating more magnesium-rich foods contribute to better brain health—especially in women—as people get older. This may lower the risk of dementia.

Misophonia is a sensory processing disorder characterized by extreme aversion to sounds people make, such as chewing, sniffling, throat-clearing, and heavy breathing. A 2023 study suggests one in five adults deals with misophonia, which can hamper family and social life. Treatment options typically blend behavior-based therapies with medication. Cognitive behavioral therapy is emerging as an evidence-based treatment. People with misophonia can also ease sound aversions by wearing earplugs or headphones and using white noise machines.

Increasing evidence suggests that people who take a daily multivitamin pill have a lower risk of cognitive decline compared with people who don't take multivitamins. In particular, two randomized controlled trials published in the spring of 2023 found that people older than age 60 who take a multivitamin are less likely to experience a slight age-related cognitive decline, at least over the next three years, compared to those taking a placebo. The benefit appeared to be particularly true for people who had cardiovascular disease.

Ignoring the warning signs of a ministroke can lead to a major stroke at a later time. People should be evaluated right away for symptoms such as speech and vision problems or weakness in an arm or leg.
