[Visual and spatial disorders and their relationship with vestibular disorders in patients with ischemic stroke]

To evaluate visual-spatial disorders (VSDs) and vestibular disorders, as well as their interrelationship in patients with ischemic stroke (IS).

The study included 60 patients (27 males and 33 females; mean age 60.1±12.2 years) in the early recovery phase of IS. Of these, 23 experienced IS in the right carotid system, 18 in the left carotid system, and 19 in the vertebral-basilar system. The mean score on the National Institutes of Health Stroke Scale (NIHSS) was 3.7. Comprehensive neuropsychological and neurovestibular testing was conducted for all study patients.

VSDs were identified in 43 patients (71.7%) post-IS, with the highest prevalence observed in strokes affecting the right carotid system, accounting for 44.2% of all cases with VSDs. Notably, 29 patients (67.4%) with VSDs exhibited vestibular symptoms. Additionally, disorders of the central vestibular-oculomotor responses (CVOR) were observed in 40 patients (93%) with VSDs. A significant correlation between CVOR disorders and VSDs was documented, especially among patients with IS in the carotid system. VSDs was shown to diminish the quality of life in post-IS patients markedly.

VSDs in post-IS patients may contribute to vestibular complications and adversely affect overall quality of life. The timely identification and management of VSD and vestibular disorders in this patient population are crucial for enhancing the efficacy of medical rehabilitation strategies.
