| Influence of Visual Processing on Cognitive Test Performance in MS | ||
| Besides depression, there are other
secondary (i.e., non-cognitive) influences that may impact cognitive
test performance in MS. In a recently completed study in my lab, we
explored another non-cognitive factor that may interfere with performance
on neuropsychological tests in MS—visual acuity disturbances.
If patients’ difficulty with visually based neuropsychological
tasks turns out to be related to more rudimentary visual acuity problems,
it could have significant consequences for our understanding of the
nature of cognitive dysfunction in MS and the way in which we measure
cognitive deficits in MS patients neuropsychologically. In a recent
study of this issue we found evidence to support our conceptualization
of the influence of visual acuity on visually based neuropsychological
tests in MS. This study is currently “in press” at JINS.
The senior author on the paper is Jared Bruce, Ph.D., a graduate student
trained in my lab who is currently on postdoctoral fellowship at Brown
University School of Medicine. The reference for this article is as
follows and a pre-print of the article can be obtained from me by
