In addition to hallmark symptoms such as persistent sadness and apathy, depression can also trigger memory problems. People with depression may lack focus, leading to memory lapses. Depression may also alter brain chemicals that help people sustain attention. Memory problems in depression show up differently than in dementia, making people unable to retrieve long-term memories. Positive memories also fade first in depression because brain areas that process positive or rewarding experiences are disrupted.

A 2023 study found that people who engaged in moderate or vigorous exercise an average of four days a week had more brain mass in regions associated with cognitive skills like memory and learning, compared with people who did not exercise.

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.

Staying socially active is associated with cognitive benefits and may play a role in longevity, stress reduction, and controlling mood. If a person has been out of touch with friends for a long time, one way to restart contact is to send a brief message asking how they're doing or recalling a shared activity. If the person reciprocates, the next step might be to suggest a meeting, ask to get together, or schedule a catch-up phone call or video chat.

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.

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.

Most older adults experience occasional "senior moments" when they forget names, misplace objects, or have difficulty following conversations. While these types of memory issues may come and go, it's when they become more frequent or severe or if new problems emerge that signals a potential issue. A doctor can help determine if underlying issues may be causing memory problems and whether further neuropsychological evaluation is needed.

Recently published research suggests that a daily multivitamin may improve memory enough such that it can function as if you were three years younger. We take a closer look at the study.
