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.

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.

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.

With ticks thriving in a wider geographic range, appearing earlier and sticking around later, it's important to stay vigilant about protecting yourself against ticks that cause Lyme disease and other illnesses. Learn some steps you can take to avoid tick bites.

Intensive blood pressure control that lowers systolic blood pressure (the first number in a reading) below 120 points may lower the risk of cognitive impairment or probable dementia.

In a 2024 study, researchers found that the short-term brain boosts people receive after doing moderate to vigorous exercise can last 24 hours.

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.

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.
