Depression is common among older adults, and insomnia doubles the risk of major depressive disorder. There is increasing evidence that treating insomnia in older people who have both insomnia and major depression has the potential to improve both their sleep and their mood.

Most skin spots are harmless, but it's important to be able to distinguish them from skin cancers and precancers.

Due to the lengthy wait for an appointment with a therapist, many people have turned to the numerous mental health apps available on smartphones. Research did not find convincing evidence that use of any such app resulted in significant improvement in symptoms, but some may be useful as a complement to therapy.

Though decades of research have suggested risk factors for amyotrophic lateral sclerosis, a specific cause remains unknown. New research studied professional football players and found that they had a much higher risk of developing ALS than men in the general population, though the study was only observational.

A study published Nov. 16, 2021, in PLOS Medicine found that drinking two to three cups of coffee as well as two to three cups of tea per day was associated with substantially lower risks for dementia and stroke, compared with drinking no coffee or tea.

A study published online Aug. 26, 2021, by The Lancet found that blood pressure treatment protects against heart attacks, strokes, and other major cardiovascular disease problems in people up to age 85 and possibly older. For people younger than 75, the study confirmed that people taking blood pressure medicines had 10% to 20% fewer cardiovascular disease problems. For people 75 to 84, there still was a 10% reduction. For people older than 85, the results were mixed, but there still appeared to be a benefit from blood pressure treatment.

The acronym SHIELD sums up the habits that may help ward off cognitive decline. SHIELD stands for sleeping at least seven hours per night, handling stress, interacting with friends, exercising daily, learning new things, and eating a healthy diet. Ideally, one should incorporate all of these healthy lifestyle habits into each day. If that feels overwhelming, doctors advise focusing on a different healthy habit per day, until it's possible to practice all of the habits every day.

A large number of apps and computer programs claim to help keep the mind sharp and improve memory. Since there is limited evidence that these programs bring cognitive benefits, be skeptical of these claims and choose the ones that you enjoy. Meanwhile, practice proven brain-protecting strategies such as staying physically active, eating a healthy diet, socializing, and avoiding brain-harming habits such as drinking excess alcohol, getting too little sleep, and using illegal drugs.
