Utility of the Spanish version of the FTLD-modified CDR in the diagnosis and staging in frontotemporal lobar degeneration.

Introduction: The Clinical Dementia Rating Scale (CDR) is a tool designed to quantify the severity of dementia symptoms and is also useful to assess disease progression, in Alzheimer's disease (AD). A new version of the scale was developed by adding two extra domains that focused on the core aspects of frontotemporal dementia symptomatology, Language and Behavior/Comportment/Personality.

Objectives: In this study, we adapted and validated the modified CDR scale in our setting and language (Rioplatense-Spanish).
