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.

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.

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.

Sudden memory lapses could be natural aspects of aging or early signs of mild cognitive impairment (MCI). With MCI, memory loss is noticeable but usually does not impede the ability to carry out daily functions. A screening test from a doctor or more advanced testing (such as brain MRI or PET scans) from a neurologist can help identify potential cognitive problems so people can seek appropriate treatment.

Having an extremely low LDL level from aggressive cholesterol-lowering therapy was not associated with cognitive impairment, according to a 2024 study.

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.

According to a 2024 study, people with high amounts of visceral fat—the deep hidden fat surrounding abdominal organs—also have higher levels of abnormal proteins in the brain that are hallmarks of Alzheimer's disease.

A 2024 study suggested that older adults who undergo cataract surgery to improve vision may have a lower risk of developing dementia.

There's no clear-cut answer about whether taking antihistamines for allergies increases dementia risk. Antihistamines have anticholinergic effects, which might increase the risk for dementia by blocking a particular brain neurotransmitter or increasing brain inflammation. But studies on whether there's any link between antihistamines and dementia have produced conflicting findings. Doctors advise taking the lowest antihistamine dose possible or using another medication for symptom relief.
