Two kinds of migraine involve visual disturbances, such as strange, flickering light patterns. One type is migraine with aura, caused by brain activity. The other is ocular migraine, caused by blood vessel problems in the eye. The attacks may or may not be accompanied by a headache. Drugs called triptans might help soothe migraine with aura. Doctors don't have a way to stop an ocular migraine attack as it's occurring. For many people, the only way to cope is resting and waiting until the symptoms go away.

A 2025 randomized controlled trial found that GLP-1 receptor agonists, the blockbuster drugs approved to treat diabetes and obesity, boosted the walking ability of people with diabetes and peripheral artery disease (PAD) in the legs. The news is encouraging, since there are few effective treatments for PAD-reduced blood flow in the limbs that leads to pain with activity. However, it will take more evidence before doctors feel comfortable prescribing GLP-1s if a person only has PAD.

Hand therapy is an effective way to overcome lost hand function due to injuries or underlying conditions. A course of therapy typically lasts for six weeks. It involves working with a certified hand therapist (CHT) who can develop and then guide someone through a tailored program of physical and functional exercises. CHTs also can make splints, offer emotional support, and help people learn to manage hand pain and swelling. It's best to start hand therapy before an injured hand has healed completely.

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.

Wooziness is often just a passing episode of lightheadedness. But it might signal something very serious, such as a stroke or heart attack. When wooziness occurs, one should sit or lie down for a few minutes, rest, and have a drink of water or juice. If wooziness eases, it's best to report the episode to your doctor. If lightheadedness hasn't improved or if it's accompanied by other symptoms, such as chest pain, trouble speaking, or weakness or numbness on one side of the body, call 911 immediately.

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.

A 2025 study found that the shingles vaccine reduced the risk of developing dementia by 20%. The study supports (but doesn't absolutely prove) the theory that infections may be one cause of Alzheimer's disease and possibly other forms of dementia.
