Area of Science:

  • Neuroscience
  • Ophthalmology
  • Geriatrics

Background:

  • Visual processing changes can indicate cognitive decline.
  • Early detection of visual deficits is crucial in dementia care.
  • The Queen Square Screening Test for Visual Deficits (QS test) is a tool for assessing visual processing.

Purpose of the Study:

  • To evaluate the applicability of the QS test in individuals with dementia.
  • To compare QS test performance between individuals with dementia and healthy controls.
  • To assess the correlation between QS test scores and cognitive impairment.

Main Methods:

  • Pilot study comparing dementia patients and age-matched healthy controls.
  • Administration of the QS test to all participants.
  • Correlation analysis with the Rowland Universal Dementia Assessment Scale.

Main Results:

  • Individuals with major neurocognitive disorder scored 50/71, minor neurocognitive disorder scored 61/71, and healthy controls scored 65/71.
  • QS test scores showed a significant correlation with cognitive impairment (r = 0.74).

Conclusions:

  • The QS test is a viable screening tool for visual processing changes in individuals with dementia.
  • The QS test is affordable, easy to administer at the bedside, and correlates with cognitive impairment.
