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.

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 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.

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.

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.

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.

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.
