Narcissistic personality disorder (NPD) can harm a person's physical and mental health and lead to problems in social and work relationships. Learn the symptoms and treatments for NPD.

A 2023 study of 93,000 people ages 65 or older found that those who said they had hobbies reported having better health, more happiness, fewer depression symptoms, and higher life satisfaction, compared with those who said they didn't have hobbies.

For the first time, consumers can order a blood screening for Alzheimer's disease. The screening looks for two types of brain proteins, one of which is associated with Alzheimer's. Doctors have concerns about the screening: it's not FDA-approved, there's little information about its accuracy, and it can take a few days to speak with a doctor about the results. By comparison, an official Alzheimer's diagnosis involves a comprehensive evaluation of someone's current and past health problems, physical and neurological exams, family history, blood tests to rule out hidden conditions that might be causing memory problems (such as vitamin B₁₂ deficiency), and imaging tests.

A 2023 study of lab animals suggests that the population of microbes in an individual's gut may influence the risk of developing Alzheimer's disease. Researchers found that healthy lab rats developed signs characteristic of Alzheimer's disease when they were injected with gut microbe samples from people with Alzheimer's. Rats that received samples from the most severely affected Alzheimer's patients developed the greatest brain abnormalities and memory problems. Rats did not develop these problems when they were injected with samples from people who had no signs of the disease.

The start of a new year is always a great opportunity for people to re-engage with their health. One of the first steps is to conduct a personal health review. It's a way to measure where a person's health stands now, outline the goals, and create a strategy to reach them. A personal health review follows a three-step process: gathering all current health information, listing short- and long-term goals, and sharing everything with a doctor during a scheduled wellness visit.

Walk with a Doc is a nonprofit program founded by a cardiologist that sponsors free, doctor-led walks in mostly outdoor venues (usually public parks) in 560 sites across America. The walks last 30 to 90 minutes, are usually held once per month, and include a five-minute talk about various health topics by the physician. In addition to the exercise and education, participants benefit from the camaraderie and time spent in nature.

An estimated 3% of adults ages 65 and older currently have dementia, and that proportion rises substantially as people age. The most convincing evidence for reducing one's risk relates to the basic foundations for an overall healthy lifestyle: aerobic exercise, a plant-based diet, and quality sleep. Aerobic exercise helps reduce the buildup of toxic proteins in the brain and improves blood flow, a plant-based diet can manage inflammation, and quality sleep helps the brain clear out harmful proteins.

People can't control the outside world, but they can control their reactions to it. A technique called cognitive restructuring can help a person change negative thinking and calm stressful reactions. It involves a four-step process, known as "stop, breathe, reflect, choose."
