Effects of auditory training in elderly with Mild Cognitive Impairment

Authorship SCIMAGO INSTITUTIONS RANKINGS

INTRODUCTION: Studies have shown the presence of an Auditory Processing Disorder in individuals with mild cognitive impairment.

OBJECTIVE: To investigate the effect of an auditory training in individuals with mild cognitive impairment.

METHODS: Twenty-five individuals with mild cognitive impairment and ages between 69 and 91 participated in the study. They were divided into three groups: a study group (10 subjects) who underwent an auditory training; an alternative group (10 subjects) who underwent to visual training and a control group (5 subjects) who did not receive any intervention.

RESULTS: After training, only the study group demonstrated better performance regarding all auditory abilities, but worse performance regarding cognitive abilities.

CONCLUSION: Auditory training was effective regarding auditory abilities but not for cognitive abilities.
