Some people have anxiety about getting medical tests such as blood work, CT scans, or MRIs. When debating whether to skip a medical test due to fear, a person should get as much information as possible about the test or ask for medication to reduce pain or anxiety associated with the test. During a medical test, it may help to do relaxation exercises or focus on something fun planned for later in the day.

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.

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.

Frontotemporal dementia (FTD) is a brain disorder caused by damage to nerves in certain parts of the brain. It typically affects people in middle age, and is characterized by marked changes in behavior or problems with language.

Dementia occurs more often among older people with higher levels of hearing loss than among those with normal hearing. A new study found that wearing hearing aids reduced the risk for dementia in people who had significant hearing loss.

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.
