A 2024 study of more than 32,000 depression-free women who were followed for 14 years found that those who ate the most weekly servings of citrus (six or more) had a 22% lower risk for developing depression, compared with those who ate the least citrus.

In a 2025 Harvard study of more than 133,000 people followed for four decades, those who ate the most red meat each day (a quarter-serving or more) had a 13% higher risk of developing dementia later in life, compared with people who ate the least.

It's fairly common for a medical treatment to cause side effects - but far more rarely, a side effect provides an unexpected benefit. This might be the case for the shingles vaccine, as evidence is mounting that it might also reduce the risk of dementia.

A 2024 study suggests that older adults who fall for financial scams may have brain changes associated with a higher risk of Alzheimer's disease.

Eating high amounts of processed red meat each day may increase the risk for future cognitive decline and dementia. Switching out processed red meat for nuts, legumes, low-fat dairy, chicken, or fish also may lower the risk.

Decreased concentration is often a normal part of aging as the brain's ability to function efficiently gradually declines. People who struggle with concentration when performing tasks can try strategies like avoiding multitasking, taking scheduled breaks, and removing distractions. Other lifestyle behaviors may also affect concentration and should be examined, such as sleep, medication, and caffeine intake. Activities like meditating, reading, and learning a new skill also can help improve mental focus.

Many people worry about occasional memory lapses that occur as they get older. To cope, it helps to talk to a doctor and also reduce stress by following healthy lifestyle habits, such as exercising, getting enough sleep, eating a healthy diet, and meditating. Using strategies to help retain information is also important. Examples include placing keys in a designated spot, taking medication at the same time each day, and using notebooks-not just memory-to organize and store information for fast retrieval.

Just as it's wise for people to take a sick day when they have a cough, fever, or nausea, certain signs indicate people need a mental health day. These include feeling burned out at work, overwhelmed by personal issues, unmotivated, exhausted by work or life demands, more anxious or depressed than usual, unable to sleep consistently, or drawn to substance use. While some spend a mental health day on indulgent activities, others run errands or tick items off their to-do list. Not taking a mental health day when needed can trigger flare-ups of depression or anxiety.
