Tennis leg refers to a strained calf muscle, usually the gastrocnemius. A person can injure the muscle during activity when planting the foot down hard or suddenly changing direction. This might happen during sports, such as tennis, or even while walking or jogging. Mature athletes, who are prone to injury, are vulnerable to the injury. Treatment can involve resting, elevating, and icing the calf muscle; wearing a compression sock; taking painkillers; getting physical therapy; and having surgery.

In May 2025, the FDA approved the first blood test to detect the early stages of Alzheimer's disease. The test looks for several proteins associated with Alzheimer's disease. About 80% of the time, the blood test is either highly positive or highly negative, a result that's accurate more than 90% of the time. Doctors expect that the test will soon be covered by insurance. If that happens, the test will become the standard of care for people ages 55 and older with Alzheimer's signs or symptoms.

Someone with a new diagnosis of diabetes might feel overwhelmed by the many strategies required to help control the disease. It helps to add several experts to the care team. Soon after a diagnosis, it's a good idea to schedule appointments with a dietitian, an eye doctor, an endocrinologist, and a certified diabetes educator. It's also helpful to add other experts as needed to the team, such as a physical therapist, a podiatrist, a social worker or an aging life care manager, and a certified health coach.

A quarter of American adults live with a mental health disorder such as anxiety, depression, obsessive-compulsive disorder, or post-traumatic stress disorder. But more than half don't seek help. Internal and external barriers may stop them from getting the care they need. Internal barriers are emotions or excuses people make to avoid treatment. External barriers include cost or difficulty finding a provider who can meet someone's individual needs. To push past obstacles, people can investigate less-expensive mental health programs or reframe guilt-inducing thoughts.

A 2025 study suggests that women who score highly on a brain health measurement incorporating physical, lifestyle, social, and emotional factors face lower stroke odds.

A 2025 study suggests that sleeping nine or more hours nightly is associated with worse cognitive performance, an effect that's stronger among people with symptoms of depression.

Toenail fungus, ingrown toenails, and brittle or cracked fingernails are common nail problems that affect older adults. They can make hands and feet unsightly and sometimes even painful. Treating these problems and preventing them from returning often takes a trial-and-error approach, diligence, and patience. Strategies include a combination of home remedies, over-the-counter medication, and good hygiene and grooming habits.

The flu virus triggers bodywide aches and pain by causing inflammation. People can ease flu aches by staying hydrated; taking warm showers; and using over-the-counter anti-inflammatory drugs such as ibuprofen (Advil, Motrin) or naproxen (Aleve).

There are currently nine trials of vaccines for Alzheimer's disease under way. All of them are in people with mild Alzheimer's or with the pre-Alzheimer's condition called mild cognitive impairment. All of the vaccines are designed to encourage the immune system to remove protein deposits from the brain. Most experimental vaccines are given by injection; one being tested at Harvard Medical School uses a nasal spray. It will be several years before we know if any of them will work.

A 2025 study suggested that getting the shingles vaccine can significantly reduce the likelihood of developing dementia, especially among women.
