Agnosia Auditory

Auditory agnosia is also called acoustic agnosia or amnestic deafness. These are disorders characterized by the inability to identify the characteristics of sounds, although the patient can understand their meaning. Such patients have difficulty distinguishing between similar sounds, for example, distinguishing between “p” and “b”. Many of the patients recognize individual words, but not the entire phrase. The inability to carry on a conversation based on understanding indistinguishable sounds also manifests itself in difficulties in understanding new sounds.

Symptoms can range from mild to extremely severe. Symptoms appear when the patient hears new information and tries to process it and remember it. Thanks to the developed ability to compare, a person can recognize close people and the surrounding area. When auditory stimuli are not available for processing, patients become much more vigilant, making a large number of errors in processing speech and information in general; at the same time, they record everything for further processing.

There are two types of hearing agnosia.

With damage to the left temporal lobe (field 42), i.e. In the sensory lobe of the brain, **acoustic agnosia** occurs, the result of which is a violation of the recognition of speech sounds - distinguishing words, understanding short phrases, auditory perception of individual speech sounds is caught, and their pronunciation falls apart. This type of agnosia (from the category of structural-sensory) is usually called acoustic.

Another variant of agnosia for spoken sounds

Auditory hallucinations are a phenomenon in which the patient hears non-existent sounds: speech, music or extraneous noise. These sounds may be well known to the patient, but they may also have completely unexpected, unfamiliar sounds, for example, childish intonations, a different speed of development, different words, etc.
