Abstract
- The interplay between vestibular disorders and visuospatial impairments has long captured scholarly attention. While evidence robustly supports visuospatial deficits in bilateral vestibulopathy, findings regarding unilateral vestibulopathy remain equivocal. Recent studies, both animal-based employing vestibular deafferentation models and human-based involving spatial cognitive tasks, hint at potential visuospatial cognitive impairments in individuals with acute and chronic unilateral vestibulopathy. Nevertheless, these results are preliminary and necessitate further rigorous investigation. The posture-first principle is evident in cognitive-motor dual tasks among patients with vestibular disorders. This review synthesizes these emergent insights, aiming to lay a groundwork for future studies that seek to elucidate this complex relationship further.
