Dissociated sensitivity disorder
The dissociated sensory loss (also dissociated sensory disorder ) is a form of sensory impairment , in which in a skin area, the temperature and pain (so-called. Protopathische sensitivity ) is disrupted or canceled while the sense of touch ( epikritische sensitivity ) and the low sensitivity is obtained. As a result, temperature and pain stimuli which z. B. set by a cold object or a needle are no longer perceived as such, but as pressure or touch. The cause is either damage to the anterior lateral cords ( spinothalamic tract ) with intact posterior cords in the area of the spinal cord or isolated damage to the spinothalamic tract in the area of the brain stem or diencephalon . Depending on the location of the damage, the disorder occurs segmentally, on one side or in cross-section (on one or both sides).
Classic examples of the occurrence of the dissociated sensory disorder are the Wallenberg syndrome , the syringomyelia and the Brown-Séquard syndrome .
