Background: Frontotemporal dementia (FTD) represents the second most frequent early onset of dementia in people younger than 65 years. The main syndromes encompassed by the term FTD are behavioral variant of Frontotemporal dementia (bvFTD), non-fluent variant primary progressive aphasia (nfvPPA) and semantic variant (SD). Aims: To assess the bvFTD and SD, which represent the most common subtypes of FTD, using visual rating scales. Methods: Brain MRI exams of 77 patients either with bvFTD (n=43) or SD (n=34) were evaluated. The rating scales used were: Global cortical atrophy (GCA), Fazekas Scale: periventricular (PV) and white matter (WM) changes, Koedam rating scale and visual scales regarding specific cortical regions: dorsofrontal (DF), orbitofrontal (OF), anterior cingulate (AC), basal ganglia (BG), ante-rior-temporal (AT), insula, lateral-temporal (LT), entorhinal (ERC), perirhinal (PRC), anterior fusi-form(AF), anterior hippocampus (AHIP) and posterior hippocampus (PHIP). Both Left (L) and Right (R) hemispheres were evaluated. Results: R-OF (p=0.059), L-OF (p |
