New findings on the effect of visual cognitive dysfunctions on mobility and support for these impairments: A review of two cases

Abstract

This case report aims to add additional knowledge to existing reports on the effect of visual cognitive dysfunction on mobility, and support for mobility through case reports and literature review. In the first case, the patient experienced visual inattention, which led the patient to miss landmarks, get lost, and experience delayed judgment when crossing roads. The other patient had metamorphopsia and abnormalities in distance judgment and optic flow, which resulted in abnormalities in distance perception during movement and climbing stairs and in landscape vision. Neither patient showed improvement in mobility with compensatory strategies using conventional visual information, such as maps and landmarks. These findings underscore the importance of considering a range of visual cognitive dysfunctions when assessing and supporting mobility after brain injury.
