To date, no publications on the use of abbreviated BNT in other degenerative pathologies with language impairment have been reported.

Objective: The objective of this study was to evaluate the usefulness of 12-item BNT in primary progressive aphasia (PPA), the behavioral variant of frontotemporal dementia (FTDbv), and AD.
