Screening tools for the identification of dementia for adults with age-related acquired hearing or vision impairment: a scoping review.

While attempts have been made to adapt cognitive tests for people with acquired hearing and/or vision impairment, the primary limitation of these adaptations is that their validity in accurately detecting dementia among those with acquired hearing or vision impairment is yet to be established. It is likely that the sensitivity and specificity of the adapted versions are poorer than the original, especially if the adaptation involved item deletion. One solution would involve item substitution in an alternative sensory modality followed by re-validation of the adapted test.
