A comparison of naming errors in individuals with mild naming impairmnet following post-stroke aphasia, Alzheimer's disease, and traumatic brain injury

Abstract

In comparing individuals with stroke, AD, and TBI, who shared mild to moderate naming impairment, subtle differences in naming errors were found. The stroke group had a higher frequency of partial responses and derivational errors, the AD group had a higher frequency of irrelevant description errors, and both the AD and TBI groups had a higher frequency of visula misperceptions. Across groups, milder naming impairment was associated with a higher proportion of semantic errors, and more severe naming impairment was associated with errors that were not semantic in nature. The results were most consistent with semantic boundary erosion
