Antidepressants influence the way brain chemicals regulate mood and other body functions and behaviors. Examples include selective serotonin reuptake inhibitors, such as fluoxetine (Prozac) and citalopram (Celexa); and serotonin and norepinephrine reuptake inhibitors, such as venlafaxine (Effexor) and duloxetine (Cymbalta). Although the medications are commonly used to treat depression, sometimes they are used to treat other conditions such as insomnia, headaches, gynecological pain, or nerve pain.

Cold weather can lead to stiff, sore muscles. To avoid that, it helps to perform two types of stretches. One type is called dynamic stretching. It involves flowing, repetitive motions that prepare muscles for activity by getting blood, oxygen, and heat to them. The other type is called static stretching. It involves holding a certain position for 20 to 30 seconds, which gently lengthens the muscles to keep them flexible. Static stretching should be performed only after the muscles are warmed up.

Sometimes mucus secretions in the lungs can persist after someone starts to get better from a chest cold, flu, pneumonia, or COVID. To cope with the problem, experts recommend two approaches. One is doing exercises that clear the lungs, such as a series of breaths and coughs that dislodges mucus. The other approach is doing exercises that strengthen respiratory muscles. An example is diaphragmatic breathing, a type of deep breathing that relies on the diaphragm muscle located below the lungs.

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.

Because falls are a serious risk for people ages 65 and older, it’s important to have an emergency plan in place. The plan should include a trusted contact who’ll be able to help in the event of a fall, and an understanding of when to call 911 versus the doctor’s office. It would also be beneficial to have a medical alert system that summons emergency contacts and 911 at the touch of a button. And it would help to consider which resources would be needed if a fall results in a long recuperation.

In 2024, the FDA approved two catheter-based devices for treating a leaky tricuspid valve. Both relieve symptoms and improve quality of life for people with moderate to severe tricuspid regurgitation, which affects about 4% of people ages 75 and older. One device is a modification of a system to treat mitral valve regurgitation that works by bringing the valve leaflets together at the areas of most severe leakage. The other device delivers a new valve made of cow heart tissue, which is commonly used in surgical valve replacements.

People sometimes wonder if the calcium they consume affects their calcium score, a test that measures calcium in the heart’s arteries to predict heart disease risk. But a 2024 study linked higher calcium intake to a lower risk of heart calcifications. Calcium helps lower blood pressure, possibly by improving the function of the lining of blood vessels. Older adults should make sure they’re getting the recommended amount of calcium in their diets. Good sources include dairy products, tofu made with calcium sulfate, almond or oat milk, canned sardines or salmon, collard greens, and kale.

Renal denervation, a nondrug treatment for uncontrolled high blood pressure, works by disrupting some of the nerves surrounding the renal arteries, which supply the kidneys. Two systems are FDA-approved for people whose blood pressure remains high despite lifestyle changes and medications. Renal denervation lowers systolic blood pressure by an average of 8 to 9 points—about the same as what people get with a single blood pressure drug. But the response varies widely; some people experience more dramatic drops, while others have no response.

People seeking motivation to be more active and connected to their community might consider signing up for a Turkey Trot, a race or “fun run” held on Thanksgiving morning. Most events are 5 kilometers (3.1 miles), and participants can walk all or part of the course. Many feature ways to support a local community charity.

People who have stable angina despite taking medications can be treated with stents or bypass surgery. The best choice depends on the location and complexity of the artery blockages and other health conditions.
