Hallucinations Vestibular

Vestibular hallucinations are one of the types of auditory hallucinations, pseudohallucinations in the form of ideas about an object that is not in the visual field and appears in the projection area in the pyramids of the temporal lobes of the brain. It manifests itself as a feeling of the presence of real sounds, which are absent or do not correspond to any real objects. This type of auditory pseudohallucination is characterized by the presence of a hallucinatory sound sensation, perceived simultaneously by all or most of the hearing field, having real, meaningful structures. They occur regardless of body position, as a rule, in an environment that promotes the preservation of motor orientation and orientation in space - primarily against the background of closed eyes, i.e., with the exclusion of the possibility of comparing acoustic and tactile influences.

A distinctive feature of vestibular hallucinosis compared to other types of auditory pseudohallucinations is that it is often combined with paralysis or dysfunction of the eye muscles and all muscle groups of the limbs. In a number of cases, patients in a state of perceptual hallucinosis can determine the location of the “culprit” of pseudohallucination: if this is a person corresponding to the physique of the hearing person, you can indicate the exact position of his body, his current location among other people. In some cases, patients determine not only the location of the missing object, but also the physical state of this person (a patient with amnesia describes what the caller is doing on the phone, what expression the person speaking has on the face). The type of fantasy almost always corresponds to the meaning of the word describing auditory phenomena. For example, the sounds of a stream before the rain are accompanied by the image of a dog running across a puddle, with the meaning “they say that it will get warmer,” and the tapping of a spoon while eating evokes a visual image of the face of a surprised person. Very characteristic of this type of hallucinatory phenomena is the unification in a single representation of the auditory and tactile accompaniment of the experienced feeling - and the patient sometimes determines the distance to the source of the sound and what other sensations arise from the hand, palm, finger: “coldness on the nail of the ring finger (with “talking” the phone in a taxi with the owner of asthmatic breathing).”

Auditory pseudohallucinations are an independent type of sensory sensitivity disorder - one of the most functional, although sometimes patients experience panic attacks of fear and a debilitating feeling of distrust of their condition. However, the appearance of vestibular-halucational disorders along with changes in other regulatory systems indicates the presence of brain damage, even organic
