Dementias: Hope Through Research (Revised December 2017) - Department Of Health And Human Services - Bog

Dementia is the loss of cognitive functioning?the ability to think, remember, or reason?to such an extent that it interferes with a person?s daily life and activities. These functions include memory, language skills, visual perception, problem solving, self-management, and the ability to focus and pay attention. Some people with dementia cannot control their emotions, and their personalities may change. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person?s functioning, to the most severe stage, when the person must depend completely on others for basic activities of daily living. Age is the primary risk factor for developing dementia. For that reason, the number of people living with dementia could double in the next 40 years as the number of Americans age 65 and older increases from 48 million today to more than 88 million in 2050. Regardless of the form of dementia, the personal, economic, and societal demands can be devastating.
