11 Facts About Auditory agnosia

Auditory agnosia is a form of agnosia that manifests itself primarily in the inability to recognize or differentiate between sounds.

All auditory agnosia patients read lips in order to enhance the speech comprehension.

Typically, a person with auditory agnosia would be incapable of comprehending spoken language as well as environmental sounds.

Nonverbal auditory agnosia is diagnosed when a person's understanding of environmental sounds is inhibited.

Auditory agnosia attributed both aphasia and auditory agnosia to damage in Lichtheim's auditory word center.

Auditory agnosia hypothesized that aphasia is the outcome of partial damage to the left auditory word center, whereas auditory agnosia is the result of complete damage to the same area.

Lichtheim proposed that auditory agnosia is the result of damage to a brain area dedicated to the perception of spoken words, and consequently renamed this disorder from 'word deafness' to 'pure word deafness'.

Term auditory agnosia was originally coined by Freud to describe patients with selective impairment of environmental sounds.

In contrast, to patients with pure word deafness and general auditory agnosia, patients with non-verbal auditory agnosia were reported impaired at discriminating long gaps between click sounds, but impaired at short gaps.

Auditory agnosia patients are often impaired in the discrimination of all sounds, including music.

Auditory agnosia is strongly dependent on damage to both hemispheres.
