Patients with chronic itch are diagnosed and treated by dermatologists. However, itch is a neural sensation and some forms of chronic itch are the presenting symptoms of neurological diseases. Dermatologists need some familiarity with the most common neuropathic itch syndromes to initiate diagnostic testing and to know when to refer to a neurologist. This review summarizes current knowledge, admittedly incomplete, on neuropathic itch caused by diseases of the brain, spinal cord, cranial or spinal nerve-roots, and peripheral nerves.
慢性瘙痒患者由皮肤科医生进行诊断和治疗。然而，瘙痒是一种神经感觉，某些形式的慢性瘙痒是神经系统疾病的首发症状。皮肤科医生需要对最常见的神经病理性瘙痒综合征有一定的了解，以便启动诊断性检查，并知道何时转介给神经科医生。本文综述了目前关于脑、脊髓、颅神经或脊神经根和周围神经疾病引起的神经病理性瘙痒的不完全知识。
