Background: There is limited information about the functional profile of behavioral variant frontotemporal dementia (bvFTD).
Objective: To compare direct and indirect assessments of activities of daily living (ADLs) in bvFTD and Alzheimer disease (AD) and their relationship with cognitive performance.
Methods: In all, 20 patients with bvFTD, 30 patients with AD, and 34 normal controls (NCs), matched for age, education, and severity of dementia, completed the Direct Assessment of Functional Performance (DAFS-BR) and usual cognitive measures. The Disability Assessment for Dementia (DAD) was completed by caregivers.
Results: In DAFS-BR, patients with bvFTD and AD had similar performance but lower than NCs. In DAD, there were no significant differences for effective performance, but patients with bvFTD had lower scores for initiation and planning/organization. Patients with bvFTD were less impaired than AD in cognition.
Conclusion: Functional changes in bvFTD seem to be better documented by indirect measures.

Introduction: Psychotropic medication (PM) use in behavioral-variant frontotemporal dementia (bvFTD) is higher than in other dementias. However, no information exists on whether PM use differs between sporadic and genetic bvFTD.
Methods: We analyzed data from sporadic and genetic bvFTD participants with PM prescriptions in the Advancing Research and Treatment in Frontotemporal Lobar Degeneration/Longitudinal Evaluation of Familial Frontotemporal Dementia Subjects study.

Background: Actigraphy is increasingly being used to assess sleep in patients with neurodegenerative diseases. However, information on its accuracy relative to polysomnography (PSG) in this clinical population remains scarce. This study investigates the performance of actigraphy compared to PSG in patients with behavioral variant frontotemporal dementia (bvFTD), which is the leading form of early-onset dementia.

Autobiographical memory is diminished in patients with behavioural variant of frontotemporal dementia (bvFTD), and research has focused on the hampered ability of patients to retrieve specific memories. In this study, we implemented a methodology seeking to provide a qualitative analysis of autobiographical specificity. We invited patients with bvFTD and control participants to retrieve autobiographical memories and we distinguished between specific, categoric, extended and semantic autobiographical retrieval.

Article Synopsis
- Poor affect recognition is an early indicator of frontotemporal dementia (FTD), and this study used the Comprehensive Affect Testing System (CATS-A) to assess emotional dysfunction in FTD patients compared to healthy controls.
- The study involved 139 FTD patients of various subtypes and tested them alongside 116 healthy controls, measuring their Affective Recognition Quotient (ARQ) to evaluate emotional recognition accuracy.
- Results showed that the CATS-A effectively differentiated between FTD patients and healthy controls with high accuracy (AUC 0.89) and had robust internal reliability, suggesting it's a valuable clinical tool for assessing emotional dysfunction in FTD.

Introduction: Diagnosis of frontotemporal dementia (FTD) remains difficult even in the presence of core clinical and imaging features. Furthermore, disease-modifying treatments are lacking.
Case Presentation: Here, we report a case of a patient with clinical and imaging features of FTD.
