Alzheimer's Disease and Dementias


Dementia causes serious loss of cognitive ability, including memory, communication and language, reason and judgment, and visual perception. Alzheimer's disease is the most common form, but all dementias go beyond the normal signs of aging to interfere with daily life, affecting millions of people each year. RAND experts analyze long-term care options and effectiveness, as well as how dementia impacts caregivers, society, and the economy.

If this happens, up to 2.1 million patients could develop Alzheimer's dementia by 2040 while on treatment and evaluation waiting lists.
