The National Institute on Aging

The National Institute on Aging (NIA) is another essential stop on the journey with dementia. As it focuses on the nature and process of health and aging, it is a crucial resource for reliable dementia research and information.

This page, called What is Dementia? Symptoms, Types, and Diagnosis, overviews the definition of dementia and the diseases that fall under its category. It introduces how diagnoses are conducted, and presents many links to other helpful topics, such as specific dementias and medical history information.
