What is Dementia?

Dementia strikes 1 of 6 Americans, and 1 of 3 seniors worldwide, but one of the most frequent questions: "What is dementia?" 

What is Dementia?

Dementia is not a disease but a medical disorder defined by cognitive decline, impaired thinking, and memory loss. People experience dramatic personality changes, emotional outbursts, and declining organizational skills. 

Some dementia versions attack language skills. Others destroy visual perception, causing delusions and hallucinations. 

Cognitive, physical, social, organizational, and vital skills deteriorate until a person can no longer manage their finances, hold a job, or remain independent. By later stages, a person requires 24/7 care. 

Fourteen primary diseases manifest into dementia.
