Assessment of aphasia: dialectal and cultural considerations in neurology.

Introduction: In the context of neurological disorders, language assessment is traditionally based on the use of the standard language of the community in which the assessment is performed. Dialectal variables constitute a 'forgotten' topic. This review aims to provide resources and working guidelines to overcome this limitation.

Development: The study was conducted as follows: 1) review of basic concepts of dialectology (language, dialect, isogloss line, idiolect, register, 'standard variant', bilingualism); 2) characterisation of Spanish and Catalan dialectologies and search for online resources for the development of neurological assessment tools; 3) ad hoc search on the PubMed database (keywords 'dialect', 'aphasia' and 'multilingual').

Conclusions: We provide online resources to promote adequate development of assessment tools in Spanish and Catalan, accounting for Dialectal considerations. We propose a set of working guidelines for the introduction of Dialectal variables in language tests to ensure their ultimate objective: to evaluate the real use of the language, and not cultural knowledge of the standard language.
