SPECT analysis and language profile in Greek speaking patients with subtypes of frontotemporal dementia.

Objective: We aimed to examine if single photon emission computed tomography (SPECT) can discriminate between variants of frontotemporal dementia (FTD). As a secondary investigation we identify and establish the linguistic differences between those variants.

Materials And Methods: Nine patients with semantic variant primary progressive aphasia (svPPA), 8 with non-fluent variant primary progressive aphasia (nfvPPA) and 17 with behavioral variant of frontotemporal dementia (bvFTD) were compared on Addenbrooke's cognitive examination-revised (ACE-R), auditory comprehension, oral expression and verbal fluency.
