multiple inflammation of the nerves. The principal causes of polyneuritis are infectious, particularly viral, diseases; intoxications, usually those caused by alcohol; and metabolic disturbances occurring with diabetes mellitus and uremia. Polyneuritis may arise with such avitaminoses as beriberi and as an occupational disease, for example, with vibration sickness or the chronic effects of cold. Usually the radices of the spinal nerves are affected (polyradiculoneuritis), the peripheral nerves, and the cranial nerves. Sometimes the central nervous system is also affected (encephalomyeloradiculoneuri-tis).
