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.

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.

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.

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.

A recent study found that engaging in high-intensity interval training may be better for brain health than other less vigorous routines.

In addition to hallmark symptoms such as persistent sadness and apathy, depression can also trigger memory problems. People with depression may lack focus, leading to memory lapses. Depression may also alter brain chemicals that help people sustain attention. Memory problems in depression show up differently than in dementia, making people unable to retrieve long-term memories. Positive memories also fade first in depression because brain areas that process positive or rewarding experiences are disrupted.

Bouts of dizziness can be unsettling sensations that may last only a few seconds or linger for several minutes or even longer. Episodes may be isolated or recurrent. Many people have a difficult time articulating what they experience when they say they feel dizzy, because the term encompasses a range of sensations like lightheadedness, wooziness, unsteadiness, or spinning. To help identify the cause, people should first consider whether they are experiencing primarily lightheadedness or vertigo.

The convenience, affordability, and flat-out fun of e-bikes and e-scooters are undeniable. But as their popularity grows, the rate of accidents involving e-bikes and e-scooters is climbing. So how do we minimize risks for accidents?
