<unk>  can be referred to as a pure aphasia because it has a high degree of specificity. Despite an inability to comprehend speech, patients with<unk>  typically retain the ability to hear and process non-speech<unk>  information, speak, read and write. This specificity suggests that there is a separation between speech perception, non-speech<unk>  processing, and central language processing. In support of this theory, there are cases in which speech and non-speech processing impairments have responded differentially to treatment. For example, some therapies have improved writing comprehension in patients over time, while speech remained critically impaired in those same patients. The term "pure word deafness" is something of a misnomer. By definition, individuals with pure word deafness are not deaf – in the absence of other impairments, these individuals have normal hearing for all sounds, including speech. The term "deafness" originates from the fact that individuals with AVA are unable to comprehend speech that they hear. The term "pure word" refers to the fact that comprehension of<unk>  information is selectively impaired in AVA. For this reason, AVA is distinct from other<unk>  agnosias in which the recognition of nonspeech sounds is impaired. Classical (or pure)<unk>  agnosia is an inability to process environmental sounds. Interpretive or receptive agnosia (amusia) is an inability to understand music. Patients with pure word deafness complain that speech sounds simply do not register, or that they tend not to come up. Other claims include speech sounding as if it were in a foreign language, the words having a tendency to run together, or the feeling that speech was simply not connected to the patient's voice.
