Generalesthesia

from Wikipedia, the free encyclopedia

Allesthesia (from the Greek ἄλλος (allos) for 'other'; αίσθησης (aísthēsis) for 'sensation', 'perception'; English allaesthesia), also allachesthesia , alloesthesia , allochery or allochemy , is defined as a qualitative change in the perception of sensory stimuli (Touch, pain, temperature, acoustic or visual stimuli). The stimuli appear at a distance from the actual location of the impact (incorrect localization). Allesthesia is a pathological symptom .

Other or similar sensory disorders are hyperesthesia (general hypersensitivity to touch stimuli), hypesthesia (general reduction in touch and pressure sensitivity) , dysesthesia (unspecific sensory disturbance) or paresthesia (non-painful, persistent sensation in the supply area of ​​a cutaneous nerve without recognizable adequate physical stimuli; "tingling ")

It is not to be confused with alliesthesia , a physiological phenomenon.

to form

There are three types of universalesthesia.

  • acoustic allesthesia

Is a disturbance of directional hearing with different acoustic effects on both ears.

  • visual allesthesia

It is about the perception of visual illusions with an apparent displacement of objects in the field of vision from the real half of the field of vision to the opposite half of the field of vision. Causes are migraines, epilepsy and lesions of the occipital lobe.

  • tactile or motor allesthesia

This is understood to mean the sensation of a tactile stimulus (touch) at a part of the body other than the place actually touched. This can e.g. B. the isolated touch of one arm, which is wrongly assigned to the opposite arm. If stimuli are generally not perceived on the contralesional side, this is an indication of a neglect .

As with other asomatognosias, the cause is usually a lesion of the right cerebral cortex (inferior parietal region, intraparietal sulcus, angular gyrus, supramarginal gyrus).

therapy

There is a physiotherapy proposed in the form of a correction of feeling about not impaired sensory systems.
