Illeteracy concerns more than 38% of Réunion Island's people older than 65 years old, which makes it an important risk factor for dementia and a limit to neurocognitive test's administration.

The MMSRun is a Mini Mental State Examination's version adapted to illeteracy and Réunionese culture, inspired by Hindi Mental State Examination's work. It allows a way better participation during neurocognitive evaluation, but it has never been validated.

This study is a peliminary study to a validation, where the concordance between scores obtained from MMSRun and from the consensual version of Mini Mental State Examination proposed by GRECO (Groupe de Réflexion sur les Evaluations Cognitives) - the only french version validated - on a hospitalized and eldery population will be analyzed.
