Happiness helps to lower blood pressure and stress, improve the immune system, and motivate people to be more active. Research suggests that, on average, genetics determines 50% of a person's general happiness level. However, a person's happiness is at least somewhat under their control, which suggests that even people who are not naturally happy have the power to increase their happiness. They can do this by practicing regular acts of happiness-activities linked with better mood and increasing optimism.

A 2024 study found that practicing 10 minutes of daily mindfulness can ease depression and anxiety and motivate people to adopt healthier lifestyle habits, such as regular exercise and better sleep.

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.

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.

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.

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.

Prolonged grief disorder (PGD) involves 12 months or longer of debilitating grief. An estimated 7% to 10% of bereaved people experience PGD. Signs include feeling as though part of you has died, marked sense of disbelief about the death, denial or immense difficulty accepting the loss, extreme loneliness, and feeling that life is meaningless. People who are more vulnerable to PGD include women in general as well as people who lost a loved one in a traumatic or unexpected way, lost a child, or have coped with anxiety or depression. Treating PGD may involve a blend of therapies.
