There are few studies describing the functional changes in behavioral variant frontotemporal dementia (bvFTD) and it is not clear which aspects of functionality are affected by the disease.
OBJECTIVE: The aim of the present investigation was to characterize the functional profile of patients previously diagnosed with bvFTD.
METHODS: The sample consisted of 31 patients diagnosed with bvFTD, who were compared to patients with Alzheimer's disease (AD) (n=31) and to healthy control subjects (NC) (n=34), matched for schooling and age. bvFTD and AD patients were matched by severity of dementia. The protocol included the Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Direct Assessment of Functional Status (DAFS-BR), Functional Activities Questionnaire (PFAQ), Disability Assessment for Dementia (DAD) and the Clinical Dementia Rating scale (CDR).
RESULTS: The group with bvFTD showed worse performance on Initiation and Planning/Organization in the DAD and on ability to feed oneself in the DAFS-BR, as well as higher scores on the PFAQ, suggesting greater dependence in the bvFTD group.
CONCLUSION: The results suggest that individuals with bvFTD display greater functional impairment compared to AD patients with a similar degree of dementia severity and to healthy controls. Direct assessment of functionality proved unable to clearly differentiate between the dementia subtypes.
