Evoked potentials suggest cranial nerves and CNS involvement in chronic relapsing polyradiculoneuropathy.
Brainstem auditory and visual potentials were recorded from 6 patients with chronic idiopathic polyradiculoneuropathy. Evoked potentials were either completely absent or their latency was prolonged suggesting slow conduction in visual or auditory pathways. The results of our study provide further evidence suggesting subclinical involvement of cranial nerves and central nervous system sensory pathways in chronic inflammatory demyelinating polyradiculoneuropathy.
