In a 2025 study of about 2,000 people (average age 80) who were followed for seven years, about a third developed dementia or mild cognitive impairment. Being socially active seemed to delay that diagnosis for about five years.

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.

A 2025 study suggested that people who eat higher amounts of processed red meat may be more likely to develop dementia than people who eat very little of it.

An active social life is good medicine for the body and brain as it lowers the risk for many chronic diseases and protects against dementia and mild cognitive impairment. However, people who are introverts and enjoy their solitude can struggle with engagement. These individuals can benefit from socializing while maintaining their comfort levels by engaging in activities like joining social clubs and other groups, taking classes, and attending public events.

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.

Engaging in prosocial, altruistic behavior that benefits other people-such as doing volunteer work, giving money to charity, or performing small acts of kindness-may be beneficial to cardiovascular health. Possible mechanisms include reductions in stress and blood pressure. Volunteering has also been associated with improvements in heart-related risks, including increased step counts and less depression.

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.

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.
