In brief: Not sensitive

Ct is insensitive and nonspecific for dementia.
Mri and pet are better, but clinical evaluation by a neurologist is most important.

In brief: Anatomy vs function

A very advanced dementia would likely show cerebral cortical atrophy and enlarged ventricles.
Earlier in the process you might not see anything at all, though -- because a ct scan registers only anatomic changes, not functional or physiological ones. These may go on for a long time, and could also result in symptoms long before anatomic changes show up on ct.
