   Why do neurons itch?

   • Neuropathological study shows clearly that injury to specific neurons is necessary to produce itch, namely, to the subset of sensory small fibers that encode itch signals, which includes C-fiber and A-delta primary afferents with various transduction patterns ( Chapter 9 ).

   What causes itch-signaling peripheral afferent neurons to itch?

   • Any type of injury to itch-signaling peripheral afferent neurons can trigger itch in and near the receptive field of the injured neurons. As with neuropathic pain, it is entirely unknown why only a few patients with such injuries (which are common) develop clinically significant NI.

   What causes widespread itch?

   • Widespread itch, by contrast, is often caused by diseases of internal organs. More than 80 percent of chronic kidney disease patients have chronic, widespread itch, and some patients with liver disease and non-Hodgkin’s lymphoma also suffer from severe itch. Certain pain medications, such as opiates, can also trigger itching.

   Oct 30, 2023 · A neurological itch (also called neuropathic itch) is caused by injury to nerve fibers in the brain, spinal cord, skin, or other parts of the body. Unlike many other types of itch, neuropathic itches often involve nerve pain and often get more intense the more you scratch.

   Although any type of lesion or injury can trigger neuropathic sensory symptoms, the most common causes are vascular compression (e.g., tic douloureux) or zoster, which can affect VI and IX as well as all three branches of V (of which involvement of V 1 or herpes zoster ophthalmicus is most common).
