Genes that helped people survive during the time of the Black Death are more likely to be found in people with autoimmune diseases alive today. Does this tell scientists anything about what surviving the COVID-19 pandemic might mean for the world's population?

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.

An estimated 30 million Americans experience some level of hearing loss, but only about 20% of them seek hearing aids. Many people can't accept they can't hear well, or won't act on symptoms. People should seek help if they have trouble hearing conversations, TV, and other sounds, and should see a doctor quickly if they have hearing loss in only one ear, pain, ear drainage, or vertigo. Visits with an audiologist and otolaryngologist (ear, nose, and throat doctor) are typically needed to get prescription hearing aids. Over-the-counter hearing aids are expected to be available online and in stores starting in late 2022.

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.

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.

In August 2022, the FDA approved a new category of safe, regulated hearing aids to be sold over the counter. The devices are meant only for people with perceived mild-to-moderate hearing loss who need to amplify the volume of sounds around them.
