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.

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.

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.

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.

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

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?

A 2024 study suggests that cognitive changes are a more reliable signal than either age or biological signs of Alzheimer's disease to foreshadow an older adult's decision to stop driving.

The 1,000 Hours Outside challenge can motivate people to spend more time outdoors by trying to accumulate 1,000 hours of outdoor time over a year.
