The brain is so ridiculously complex, in fact, that in considering it in any depth one can only reasonably wonder why it works so well so much of the time.- David Shenk

What is Alzheimer's?

What is Alzheimer's and related dementia?
Dementia is a loss of intellectual functions (such as thinking, remembering and reasoning) that is severe enough to interfere with a person's everyday life. Symptoms may include short-term memory loss, inability to think problems through or complete tasks, confusion, difficulty concentrating, and behavior changes. Some disorders that can cause dementia include: Alzheimer's disease; Vascular disease; Lewy Body dementia; Huntington's disease; Pick's disease; Creutzfeldt-Jakob disease and Parkinson's disease. Dementia is not a part of normal aging. Alzheimer's disease is the most common cause of dementia, affecting an estimated 5.3 million Americans, Alzheimer's disease is a progressive, degenerative disease that attacks the brain and results in impaired memory, thinking and behavior.

More than 35 million people worldwide will have dementia in 2010, according to the 2009 World Alzheimer's Report from Alzheimer's Disease International (ADI). International studies make it clear that dementia occurs in every country of the world. Dementia affects 1 in 20 people over the age of 65 and 1 in 5 over the age of 80. According to the new report, dementia prevalence will nearly double every 20 years, to 65.7 million in 2030 and 115.4 million in 2050.
