Photographic Project - Dementia

I have decided to take my next project towards making a response to an emotional issue - Dementia. I want to try to communicate visually what dementia is using the still image. I am at the experimental stage manipulating photographs. I want to set a scene before I record the image.

I have been looking at herbal remedies that are used in connection with senality and dementia. Also the feelings and emotions that come to mind when the majority of people think of dementia -

Lonely
forgetful
lost
scared
indifferent
sad
frustrated
clumsy
