Carol Bradley Bursack, AgingCare.com's Community Moderator, has done a great job describing the various stages of Alzheimer's disease, the most common form of dementia.
I am including a link to the article:

Bad then worse.2!Dementia is a kinder word for Alzheimers.No cure and will get worse. A doctor can give medication to help some of the symptons.My Mom also has Sundowners.She gets very confused and paces back and forth.Also gets mean and snappy.As people now live longer we will see this is truely a epidemic and burden.
