Abstract

Behavioral variant frontotemporal dementia (FTD) and primary progressive aphasia (PPA) are related dementias with different presenting symptoms but with increasing symptom overlap as they progress. Loss of insight is associated with early behavioral variant FTD, but not PPA. This study used the Frontal Behavioral Inventory to compare patient and caregiver concepts of symptom presence and severity. Patients with behavioral variant FTD were found to have worse insight overall than PPA patients. However, the PPA group showed reduced insight into behavioral symptoms, and the behavioral variant FTD groups had intact insight into some language symptoms. Theoretical and clinical implications are discussed.
