Top Definition
A devastating condition that many elderly people enter. It often results in progressive memory loss and an inability to perform basic tasks.

It is not an illness perse, but rather a series of symptoms that may be associated with many diseases such as Huntington's disease.

People with dementia live in realities of their own.

Demented person: I'm going to bed!

Me: Huh?

Demented person: Can I kiss you?

Me: :( //backs away nervously
