Some scientists believe that microbes might play a part in Alzheimer's disease development. They say it could be that certain viruses or bacteria that infect the brain aren't completely eradicated by the immune system, which leads to neuroinflammation and brain cell death. It could also be that microbes trigger the release of protein deposits-amyloid-beta plaques and tau tangles-which kill neurons, further increase neuroinflammation, and lead to more neuron death.

At some point, most older adults experience the occasional "senior moment" where they misplace an everyday object, lose their train of thought during a conversation, or forget why they walked into a room. Memory lapses like this are part of normal aging, but the problem can be exacerbated by issues like depression, stress, poor sleep, and medication side effects. If these episodes become so frequent or substantial that they interfere with a person's daily life or safety, it's time to see a doctor.

A 2024 study suggested that closely following the MIND diet, which emphasizes plant-based foods and limited animal products and saturated fats, may slow cognitive decline compared to other eating patterns.

In the US, supplements are not tested in the way prescription medicines are, and their manufacturers can make claims about their abilities that may or may not be true. But there are some rules supplement makers must follow, and the FDA's plan to revamp its regulation of dietary supplements is a step toward improving consumer protection.

A 2024 study found that practicing 10 minutes of daily mindfulness can ease depression and anxiety and motivate people to adopt healthier lifestyle habits, such as regular exercise and better sleep.

Happiness helps to lower blood pressure and stress, improve the immune system, and motivate people to be more active. Research suggests that, on average, genetics determines 50% of a person's general happiness level. However, a person's happiness is at least somewhat under their control, which suggests that even people who are not naturally happy have the power to increase their happiness. They can do this by practicing regular acts of happiness-activities linked with better mood and increasing optimism.
