A 2022 review of dozens of randomized controlled trials and observational studies found that people who used hearing aids or cochlear implants had a 19% lower risk of cognitive decline, compared with people who didn't use the devices.

A 2022 observational study that included more than 200,000 people found that those who'd had shingles at some point had a 30% higher long-term risk for a major cardiovascular event, compared with people who didn't have shingles.

Making one or more trips to the bathroom every night is the defining characteristic of a medical condition called nocturia. It can be caused by aging, lifestyle habits, or underlying conditions such as an overactive bladder or (in men) an enlarged prostate. Treating nocturia starts with lifestyle changes such as avoiding fluids several hours before bedtime, eliminating caffeinated drinks 10 hours before bedtime, and limiting evening alcohol intake. Medications, pelvic floor exercises, injections of botulinum toxin (Botox), or nerve stimulation treatments may also help.

Over-the-counter hearing aids are now available in stores and online. They're regulated by the FDA, they don't require a prescription from a doctor, and they're cheaper than prescription hearing aids. But over-the-counter devices are not right for everyone. They're meant only for adults with perceived mild to moderate hearing loss. Before buying a pair, a person should do some homework to find devices with the right fit and features, including a trial period that allows the buyer to return them if they aren't working out.

COVID-19 can damage the brain in many ways. Initially, it can cause brain inflammation that causes confusion, difficulty concentrating, and memory problems. COVID also can cause new psychological disorders such as depression or anxiety. It can even cause people to see and hear things that aren't there and to believe things that aren't true. COVID often damages the brain's autonomic nervous system, leading to abnormalities in heart rate and blood pressure. Additionally, the virus that causes COVID can infect and injure the lining of blood vessels and make blood clot more easily, which can lead to strokes and heart attacks.

Sometimes people miss the symptoms of life-threatening conditions such as a heart attack, a stroke, atrial fibrillation, or a pulmonary embolism. To detect the warning signs, people should pay attention to sudden, new symptoms, especially if they include shortness of breath, chest pain, heart palpitations, lightheadedness, confusion, weakness, fatigue, fainting, or a terrible headache. Someone experiencing any of these symptoms should call 911. If symptoms aren't sudden or intense, and people aren't sure if they warrant emergency help, they should call their doctor.

Stroke is the most common cause of aphasia, a language-based brain disorder that can affect speaking, understanding, reading, and writing. But the brain has the ability to rewire brain cells and recover lost function through a process known as neuroplasticity. Therapy with a speech-language pathologist facilitates this recovery, which is greatest in the first several months after a stroke. Stroke survivors who keep working on their language processing problems can continue to improve for years.

A pre-surgery consultation with the surgeon can feel overwhelming. Many people are anxious and have questions about what's to come. Setting the right expectations on both sides can ease anxiety and help define a successful outcome.

Lifestyle changes like regular exercise, a healthy diet, and sufficient sleep are cornerstones of self-care for people with type 2 diabetes. But can mind-body practices help people manage or even treat type 2 diabetes? An analysis of multiple studies suggests they might.
