• PSYCHOLOGICAL AND PATHOLOGICAL ASPECT OF ITCH

抄録

It has become clear that the neuron for itch is different from that of pain, though the conductive way of an itch is about the same as that of a pain. Itch is modified at the peripheral nervous system by pruri-potent materials formed with the inflammation and so on, and at the central nervous system ornamentation is taken by opioids. Finally, itch is recognized in the cerebrum. The scratch behavior, which is usually associated with itch, is governed by the center of the distal medulla. It is suggested that itch does not provoke spinal reflex of scratching but induces scratching by a signal in the associated areas of the cerebral cortex. Pain inhibits itch with both being linked with one another. It is reported that the recognition of itch in the cerebral cortex sometimes changes due to mental condition or by the surrounding environment. Anxiolytics, antipsychotics and opioid antagonists as well can be used in the control of itch, though it is general to have antagonists to pruri-potent materials. However, there is no medicine which specifically controls the scratch behavior at present. The main stream treatment is behavior therapy though it is less popular among dermatologists.
