[Coping and Supporting Patients and Families of Frontotemporal Lobar Degeneration].

Frontotemporal lobar degeneration (FTLD) is a comprehensive term encompassing a group of clinically overlapping but heterogeneous conditions with selective frontal and temporal lobar neurodegeneration. Among the three clinical subtypes of FTLD, behavioral variant frontotemporal dementia (bvFTD) and semantic dementia (SD) were specified as "designated intractable diseases" by the Japanese Ministry of Health, Labor and Welfare in 2015. Under this designation system, relatively young patient with bvFTD or SD of certain severities can receive partial financial support from the Japanese local government. Here we introduce financial and social support for FTLD, including utilization of the designated intractable disease system and other support available in Japan. In addition, we describe the methods for coping and care of prominent symptoms in FTLD. Lastly, we address the current status of a nationwide Japanese FTLD study cohort named FTLD-J.
