Post Cort Atrophy: Alzheimer's initially is believed to affect temporo-parietal areas but as the disease progresses eventually will include the cortex throughout. Posterior cortical atrophy as a focal process is not characteristic of AD. Could he have a PRION disease? Write me at: www.healthtap.com/drsaghafi Use Key Code: PDXFNR to make an appointment. There is a 3 hr. difference from Cleveland to San Diego.

Patterns: Alzheimer's could cause pre-dominant atrophy over temporal and parietal areas, and Fronto-temporal dementia would show localized patterns. However, on occasion, Lewy Body Dementia can cause focal involvement of the Occipital lobe. Can substantiate this via 3-D SPECT scan or a PET scan, and this is of value as the treatment in Lewy Body disease varies from Alzheimer's.
