Memory impairments in adults with neurogenic communication disorders.

Over the past few decades, there has been increasing interest in the nonlinguistic, cognitive abilities of adults with neurogenic communication disorders. In particular, a growing literature has documented deficits in a number of memory functions in this population. The purpose of this article is to summarize that literature and provide an overview of the presence and nature of memory impairments in aphasia, right hemisphere disorders, traumatic brain injury, and dementia. Ways that memory impairments may interact with the communication abilities of individuals with neurogenic communication disorders also are discussed.
