In a 2025 study of nearly a million people with diabetes, those who took GLP-1 drugs had a reduction of 10% to 20% in heart failure, cardiac arrest, lung failure and pneumonia, and dementia, compared with people who took other diabetes medications.

People with prediabetes may be able to reduce their risk of developing type 2 diabetes with 150 minutes of moderate-intensity exercise per week, says a 2025 study. Exercise can help lower blood sugar and excess weight, the main risk factors for progression of prediabetes to type 2 diabetes.

The vast majority of older adults would want to know if they're in the early stages of Alzheimer's disease and would want a blood test to learn for certain, according to a 2025 poll. Advances in testing and treatment may fuel this desire for knowledge. There are pros and cons to knowing this information. People with an early Alzheimer's diagnosis can plan ahead, seek support, and may feel motivated to maintain their health. But the diagnosis may jeopardize their job or insurance coverage, as well as trigger anxiety or depression.

People with high blood pressure typically die earlier than people without the condition. A 2025 study suggests that they can significantly lower-or even eliminate-that difference by controlling several key risk factors.

Flashes and floaters are eye problems that become common with age. Over time, they may become less noticeable, but people should seek medical care if symptoms worsen, as this could be a sign of a retinal detachment.

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.
