FRONTotemporal dementia Incidence European Research Study—FRONTIERS: Rationale and design

Abstract

Introduction: The incidence of Frontotemporal Lobar Degeneration (FTLD)–related disorders and their characteristics are not well known. The “FRONTotemporal dementia Incidence European Research Study” (FRONTIERS) is designed to fill this gap. Methods: FRONTIERS is a European prospective, observational population study based on multinational registries. FRONTIERS comprises 11 tertiary referral centers across Europe with long-lasting experience in FTLD-related disorders and comprehensive regional referral networks, enabling incidence estimation over well-defined geographical areas. Endpoints: The primary endpoints are (1) the incidence of FTLD-related disorders across Europe; (2) geographic trends of FTLD-related disorders; (3) the distribution of FTLD phenotypes in different populations and ethnicities in Europe; (4) inheritance of FTLD-related disorders, including the frequencies of monogenic FTLD as compared to overall disease burden; and (5) implementation of data banking for clinical and biological material. Expected impacts: FRONTIERS will improve the understanding of FTLD-related disorders and their epidemiology, promoting appropriate public health service policies and treatment strategies.
