[英文釋義] Diseases of multiple peripheral nerves simultaneously. Polyneuropathies usually are characterized by symmetrical,bilateral distal motor and sensory impairment with a graded increase in severity distally.

The various forms of polyneuropathy are categorized by the type of nerve affected (e.g.,sensory,motor,or autonomic),by the distribution of nerve injury (e.g.,distal vs. proximal),by nerve component primarily affected (e.g.,demyelinating vs. axonal),by etiology,or by pattern of inheritance.
