When you are sick of either three-dimensional or two-dimensional media, so you want to see something different.
Whenever I get dementia, I switch from Super Mario Bros. to Super Mario 64, and when I get sick of both, I crave a fourth-dimensional Mario game, so now I'll have dementia until Nintendo makes that.

When you get told to go to do a certain task, told about 30 seconds ago. You then walk to the room knowing the task. As soon as you enter the room you instantly forget the task. I have know idea how this happens or if the doors have dark magic or something. But the only logical explaination is that i have dementia.

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.
(At a nursing home, facing person with dementia)

Demented person: Hi, what's your name?

Me: Hi! I'm Ken. What's your name?

Demented person: I'm going to bed!

Me: Huh?

Demented person: Can I kiss you?

Me: :( //backs away nervously
