ABSTRACT

The Queen Square Screening Test for Visual Deficits (QS test) screens for changes in visual processing. Our pilot study aimed to review the applicability of the QS test in individuals with dementia compared with those with normal cognition. Participants with major and minor neurocognitive disorder scored 50/71 (n=12) and 61/71 (n=10) respectively on the QS test, compared to 65/71 for age-matched healthy controls (n=11). The QS test score correlated with cognitive impairment as measured using the Rowland Universal Dementia Assessment Scale (r = 0.74). The QS test is an affordable and easy bedside screening test for visual processing changes.
