Several types of "electroceutical" therapies use tiny zaps of electricity to help ease chronic pain. Transcutaneous electrical nerve stimulation (TENS) therapy and electroacupuncture are designed to work by interrupting pain signals being sent to the brain. Scrambler therapy is thought to work by changing pain information sent to the brain. Good candidates for such therapies are people with arthritis, neuropathy, neck or back pain, or pain from cancer treatment. Some people should stay away from electroceuticals, including those with any kind of implanted stimulation device, such as a pacemaker or bladder stimulator.

Everyone goes through periods when they feel low, lethargic, or stressed. These episodes usually pass after a while, but if symptoms linger or begin to interfere with daily life, people should seek professional help. Otherwise, people can take several steps to boost their mood, such as exercising more, spending time outdoors, volunteering, meditating, and keeping a gratitude journal.

A 2023 study found a link between excess abdominal fat and lower brain volume, particularly in regions involved in thinking, memory, and performing everyday tasks.

A pulled muscle sometimes feels similar to a pinched nerve. But muscle pain is usually dull and doesn't radiate outward, while pinched nerve pain is sharp and burning and extends from one area to another. Pinched nerves can stem from pregnancy, arthritis, or injuries.

Young-onset dementia, which occurs in people younger than age 65, is uncommon. A new study has identified 15 factors linked to a higher risk of young-onset dementia.

For the first time, consumers can order a blood screening for Alzheimer's disease. The screening looks for two types of brain proteins, one of which is associated with Alzheimer's. Doctors have concerns about the screening: it's not FDA-approved, there's little information about its accuracy, and it can take a few days to speak with a doctor about the results. By comparison, an official Alzheimer's diagnosis involves a comprehensive evaluation of someone's current and past health problems, physical and neurological exams, family history, blood tests to rule out hidden conditions that might be causing memory problems (such as vitamin B₁₂ deficiency), and imaging tests.

A 2023 study of lab animals suggests that the population of microbes in an individual's gut may influence the risk of developing Alzheimer's disease. Researchers found that healthy lab rats developed signs characteristic of Alzheimer's disease when they were injected with gut microbe samples from people with Alzheimer's. Rats that received samples from the most severely affected Alzheimer's patients developed the greatest brain abnormalities and memory problems. Rats did not develop these problems when they were injected with samples from people who had no signs of the disease.

An estimated 3% of adults ages 65 and older currently have dementia, and that proportion rises substantially as people age. The most convincing evidence for reducing one's risk relates to the basic foundations for an overall healthy lifestyle: aerobic exercise, a plant-based diet, and quality sleep. Aerobic exercise helps reduce the buildup of toxic proteins in the brain and improves blood flow, a plant-based diet can manage inflammation, and quality sleep helps the brain clear out harmful proteins.

A 2023 study suggests that people who average 10 or more hours sitting each day face higher risks of dementia than those who sit less, and those risks persist even if they exercise.
