Abstract
This article summarizes various types of lexical retrieval impairments that can occur as a result of acquired brain injury. Lexical impairments, or naming deficits, are a hallmark of almost all aphasia types. However, lesion studies of patients with damage to specific brain areas have indicated that lexical retrieval impairments retrieval can occur in isolation, and in these cases the term anomic aphasia applies. It has also been shown that when anomic aphasia occurs, it can manifest itself differently depending on the neural structures that were damaged. For example, specific lexical impairments for unique people and places, animals, and tools have been observed in patients with damage to the left temporal lobe. Differential neural structures have also been implicated in the processes required for lexical retrieval of nouns versus verbs. This article describes the nature and types of lexical deficits, as well as the neural substrates that are involved.
