A 2024 study suggests that older women with higher scores on tests to assess gratitude may live longer than those with lower scores. Most of this benefit seems to come from preventing deaths from heart disease.

A 2024 study suggests that older adults who are chronically lonely are significantly more likely to have a stroke.

Restless legs syndrome (RLS) affects up to 10% of Americans and twice as many women as men. Risk factors include age, genetics, iron-deficiency anemia, and pregnancy. A variety of therapies can alleviate symptoms, which are dominated by creepy-crawly, sometimes painful leg sensations that tend to strike around bedtime. The American Academy of Sleep Medicine recommended in March 2024 to stop using dopamine-boosting drugs as first-line therapy for RLS; it should be taken only by patients whose symptoms don't respond to other treatments.

A 2024 study suggests that having an attitude of gratitude may help people live longer.

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 subconjunctival hemorrhage is a broken blood vessel in the eye. It's usually not serious and resolves on its own within two weeks. People who also experience eye pain or vision changes may have an eye infection and should see a doctor.

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.

A 2024 Harvard study involving more than 84,000 diabetes-free people (average age 62), who were followed for seven years, found those whose sleep duration varied most had a 34% higher risk for diabetes, compared with those whose sleep duration varied the least.

In a 2024 Harvard study involving more than 49,000 women (average age 79), those who reported feeling the most grateful had a 9% lower risk of dying over the following three-year period, compared to those who reported feeling the least grateful.
