A heart disease diagnosis may trigger a bout of depression. But having depression can also leave people more vulnerable to heart disease. Some of the overlap stems from shared lifestyle factors, such as inactivity and an unhealthy diet. In addition to addressing those issues, other safe and effective ways to ease depression include working with a therapist, using a light box, and taking medications.

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.

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.

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.

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 finds that a first-time transient ischemic attack (TIA) can lead to the same long-term decline in thinking and memory problems as a full-blown stroke. Experts suggest cognitive testing after a TIA. People who have TIAs should take extra care to address risk factors for heart attack and stroke, such as high blood pressure and high cholesterol. Exercising regularly and staying socially active may help ward off cognitive decline.

In a 2025 study, people with the healthiest diets and trimmest bellies at midlife had better brain connections and skills decades later, compared with people who ate the worst diets and had the most belly fat.

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

Mindfulness might help improve attention and memory. Mindfulness is the practice of focusing on the present moment, including thoughts, feelings, and all information coming in from the senses, such as sights, sounds, and smells. Many studies have shown that mindfulness helps people improve well-being, concentrate, engage more effectively in daily activities, and pay more attention. Attention is the most crucial factor when it comes to memory; whatever someone pays attention to is what he or she remembers.

Doctors are optimistic that artificial intelligence (A.I.) will one day play a role in curing and preventing Alzheimer's disease. One example of A.I.'s application is its use in helping scientists learn how certain molecules might cause Alzheimer's.
