Nothing: Imaging cannot diagnose "functional" problems, such as dementia, etc. Imaging such as ct/ MRI can only assess anatomy. It is common to have a normal study with dementia.

PET scan: Newer imaging techniques and particularly physiologic imaging can show changes with dementia. Also a nuclear test called a cisternogram can help diagnose normal pressure hydrocephalus, a treatable cause of dementia. Also MRI can detect abnormalities ct cannot, so it may be useful.
