As the world’s population ages, there will be more and more dementia cases.

Dementia means the brain loses abilities, such as memory or communication skills. It’s caused in various ways, including strokes, narrowed or clogged arteries blocking blood flow, Alzheimer’s disease and head injuries.

Steps to protect the brain are similar to those that people should take to protect the heart, such as eating healthy, exercising and not smoking.
