A 2023 study suggests older adults with vision problems, including up close or at a distance, face significantly higher risks of dementia than those with no vision problems.

Both loneliness and isolation were associated with poor health outcomes in a 2023 study. However, social isolation was a stronger predictor of physical decline and early death, while loneliness was more predictive of mental health issues such as depression.

Drinking excessive amounts of alcohol and feasting on foods high in natural compounds called purines may trigger gout in some people. Purine-rich foods that might be found on a holiday buffet include roast beef, brisket, lamb or pork chops, veal, chicken liver, turkey, trout, haddock, scallops, oysters, mussels, lobster, shrimp, or crab. While it's not necessary to completely shun alcohol and foods high in purines, doctors advise limiting them and sticking to a plant-based diet when possible, even during the holidays.

Continuous positive airway pressure (CPAP) is a first-line treatment for people with obstructive sleep apnea. The CPAP keeps the airway open by pushing a forceful stream of air through a tube and into a mask worn during sleep. The air comes from a small bedside pump (an air compressor). Other forms of positive airway pressure (PAP) may be helpful for people with central sleep apnea. Doctors determine which type of PAP therapy and device someone needs. Patients select the type of PAP mask to use with the system.

Cellulitis, a skin infection that often occurs on the lower leg, develops when bacteria enter the body through a cut, bite, or other wound. A new study shows key aspects of healing typically occur within 10 days of treatment, but symptoms can linger for some time after that.

Older people tend to have more difficulty focusing than young people. This is because age-related brain changes make it harder to filter out stimuli that are not relevant to the task at hand. Tips to try to boost concentration include practicing mindfulness; engaging in cognitive training; and living a healthy lifestyle that includes managing underlying conditions, eating a Mediterranean diet, and getting the recommended amounts of exercise (150 minutes per week) and sleep (seven to eight hours per night).

Hyperthyroidism means that there is abnormally high amounts of thyroid in the blood stream. Hyperthyroidism can happen when the thyroid gland either makes or secretes excess thyroid hormone or when people take a higher dose of thyroid pills than they need. Although some observational studies suggest hyperthyroidism may increase the risk of infection, hyperthyroidism should not make a person immunocompromised.

Virtually everyone carries the bacteria Clostridioides difficile, or C. diff. But half a million Americans a year develop a serious C. diff infection due to a gut microbiome imbalance. It disproportionately strikes people in hospitals and nursing homes, and can recur repeatedly.

Mnemonics are techniques for recalling information. One type of mnemonic is called "look, snap, connect," which uses visualization, word association, and storytelling to help solidify a memory so people can recall it later.
