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.

Scientists are studying two novel approaches to improve memory. One approach centers on molecules in the blood and spinal fluid that appear to help improve memory. So far, experiments have been limited to lab animals. Another approach involves exposing the brain to electrical currents. A study in humans, published online Aug. 22, 2022, by the journal Nature Neuroscience, found that electrical stimulation directed at specific areas of the brain improved both working memory and long-term memory for at least a month.

There are many misconceptions about dementia. One is that it's a disease. In fact, dementia is a general term describing thinking and memory skills that have deteriorated to the point of experiencing problems with daily activities. Another myth is that dementia is part of normal aging. It isn't; dementia is simply more common as people get older — just like heart disease, stroke, and cancer. Other common myths about dementia include the notions that it always appears as memory loss, it's always genetic, it causes the loss of all memories, and it's never reversible.

A 2022 study found that people with chronic kidney disease were less likely than similar adults without the condition to eat fruits and vegetables. Researchers said more studies are needed to determine if this dietary pattern is a cause or a result of the disease.

In recent years, treatment options for inflammatory bowel disease have expanded rapidly, with new types of drugs, new medications within existing classes, and new combinations of treatments for some patients.

Light therapy can help improve seasonal affective disorder (SAD). But many people don't realize that it can also be effective for major depression, and depression that occurs during or after pregnancy (known as perinatal depression).

Could identifying early warning signs of psychosis and providing appropriate support change the course of the illness? Early-intervention programs aim to do this with at-risk teens and young adults, and those experiencing a first episode of psychosis.

Life expectancy is one measure of the general health of a population. In the US, life expectancy had been climbing for more than a century — until the pandemic. After dropping in 2020, it dropped again in 2021, and some population groups fared worse than others.

Transcranial magnetic stimulation helps some people with treatment-resistant depression, but the process takes multiple weeks and gets results in only about a third of those who try it. A new approach to delivering this therapy showed promise in a small study.

When people are going through difficult times, it's normal to feel a lack of joy. But even while struggling, the ability to find moments of joy can have profound and far-reaching effects on the mind and body.
