| Annotation | Visual and cognitive impairments are common in later life, however there are very few cognitive screening tests for the visually impaired. The objective of the present study was to screen for cognitive impairment in the visually impaired. The research used a case-control study including 150 older participants with visual impairment and a control group without visual impairment using vision-independent cognitive tests and cognitive screening tests. The tests consisted of MMSEs (mini mental state examinations) and clock drawing tests (CDTs), the latter being in part vision dependent. Results showed that the scoring of the two groups did not differ in the vision-independent cognitive tests. Visually impaired patients performed poorer than controls in the vision-dependent items of the MMSE and CDT. No group difference was found when vision-independent items were added to MMSE and CDT. The test score gain by the use of vision-independent items correlated with the severity of visual impairment. The authors conclude that visually impaired patients benefit from cognitive tests which do not rely on vision. The more visually impaired the greater the benefit. (JL). |
