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.

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.

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

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.

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.

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

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.

A 2024 study of more than 10,000 dementia-free people found that fitting the recommended amount of weekly exercise into one or two sessions was associated with a similar reduction in dementia risk as exercising throughout the work week.
