A 2025 study of 250 people found that the brain can tell the immune system to prepare for impending infection even before a microbe enters the body. Scientists asked volunteers to don virtual reality headsets that showed various virtual people approaching them. Some of those approaching appeared to be healthy and others appeared to be sick. Brain scans and blood tests showed that participants' brains activated their immune systems when a virtual sick person simply came near them.

A 2025 study suggests that owning a dog or cat may help slow cognitive decline as people age.

Chronic pelvic pain-medically known as chronic prostatitis / chronic pelvic pain syndrome, or CP/CPPS-is one of the more common and challenging conditions older men face. Because the underlying cause may not be identified, doctors often take a trial-and-error approach to managing the common symptoms like throbbing, aching pain, urination problems, and sexual dysfunction. Options include different types of medication, physiotherapy, shock wave therapy, and aerobic exercise.

An x-ray, CT scan, or MRI is usually not needed for addressing low back pain unless people have other symptoms or risk factors for a serious condition. Short-term rest, heat or cold, and over-the-counter medication can ease discomfort until the back pain goes away.

People who suffer from chronic insomnia are more likely to develop cognitive problems and score lower on thinking and memory tests compared with individuals without chronic insomnia, a 2025 study suggests.

In a 2025 study, adults 45 and older with a strong sense of purpose were 28% less likely to develop cognitive impairment or dementia compared with individuals who had a low sense of purpose.

A 2025 study of over 5,600 women and men followed for over 30 years found that following a Mediterranean diet may reduce the risk of Alzheimer's disease and improve cognitive function. The effect is strongest in people who carry two copies of the Alzheimer's risk gene APOE4.

A 2025 study suggested that consuming larger amounts of artificial sweeteners such as aspartame and xylitol may be linked to faster declines in memory and thinking skills.

Chronic back pain (pain that lasts more than 12 weeks) can be more challenging to diagnose and treat compared to short-term pain from an injury. The first-line approach is conservative treatment, such as over-the-counter pain medication, physical therapy, and lifestyle changes. However, sometimes these are not enough, and advanced methods are needed. Depending on the source of chronic back pain, these can include stronger prescription medication, corticosteroid injections, and surgery.

The vast majority of older adults would want to know if they're in the early stages of Alzheimer's disease and would want a blood test to learn for certain, according to a 2025 poll. Advances in testing and treatment may fuel this desire for knowledge. There are pros and cons to knowing this information. People with an early Alzheimer's diagnosis can plan ahead, seek support, and may feel motivated to maintain their health. But the diagnosis may jeopardize their job or insurance coverage, as well as trigger anxiety or depression.
