Research conducted on test taken by dementia sufferers
A visual recognition test taken by dementia sufferers has proven useful in differentiating between visual problems with neurological origins, from those with ocular causes.
Research conducted by the College of Optometrists, with researchers at the Dementia Research Centre at University College London, investigated the experiences of vision assessment for people living with a form of dementia that impacts vision loss.
Posterior cortical atrophy (PCA) can result in abnormal visual phenomena, such as finding it easier to read smaller text than larger ones, as well as visuospatial problems. This can lead to misdiagnosis unless health professionals are aware of, and test for, the condition.
