A 2024 study involving more than 149,000 people, middle-aged and older, found that those who had shingles were 20% more likely to notice signs of cognitive decline years later, compared with those who didn't have shingles.

For stroke survivors, workouts that alternate high- and low-intensity exercise (known as high-intensity interval training or HIIT) may boost fitness more than moderate-intensity workouts.

In a 2024 study of 900 dementia-free older adults, those who developed mild cognitive impairment had lower levels of life purpose and personal growth years before a diagnosis, compared with those whose thinking skills remained sharp.

Some people find it difficult to meditate, perhaps due to inexperience, stress, or chronic pain. To overcome meditation resistance, it helps to take a meditation class or work with a meditation coach; use a meditation app; meditate in a setting free of interruption; meditate at the same time each day, so it becomes part of a daily routine; and try various meditation styles, such as Transcendental Meditation, mindfulness meditation, or guided meditation, to see which one is most comfortable.

Antidepressants influence the way brain chemicals regulate mood and other body functions and behaviors. Examples include selective serotonin reuptake inhibitors, such as fluoxetine (Prozac) and citalopram (Celexa); and serotonin and norepinephrine reuptake inhibitors, such as venlafaxine (Effexor) and duloxetine (Cymbalta). Although the medications are commonly used to treat depression, sometimes they are used to treat other conditions such as insomnia, headaches, gynecological pain, or nerve pain.

A study published in JAMA in July 2024 found that a blood test was accurate in diagnosing Alzheimer's disease, which causes steep declines in cognition and other aspects of health. The blood test is able to detect elevated blood levels of brain proteins that characterize the condition. While that's progress, doctors say it's not the test needed most. It would be more beneficial, they say, to have a test that accurately spots the developing disease long before it affects thinking. No such tests are here yet, but scientists are working to develop them.

The Brain Care Score is a quiz developed to help people identify proven, actionable steps to lower their risk of stroke, dementia, and depression. It includes four physical components (blood pressure, blood sugar, cholesterol, and body mass index); five lifestyle components (nutrition, alcohol intake, smoking, aerobic activities, and sleep); and three social-emotional components (stress management, social relationships, and meaning in life). Each response is given a point value, with the highest possible score totaling 21. Higher scores mean better brain care.

When ADHD persists through early adulthood into middle age, it presents many of the same challenges it does in childhood, but with added pressures from the busier pace of life and expectations from work and family. Fortunately there are strategies that can help you navigate this condition.
