All 44 individuals were assessed using the BFI, CDR, MMSE and FAQ. Thus, duration of dementia and education level (in years) were also examined and served as inputs for the survival analysis. The neurological examination was performed during the same period as the clinical imaging. The patients were divided into two groups: one with FTD (n=23) and the other with AD (n=21). The BFI was compared in both groups for all analyzed variables.
