title: Pattern-reversal visual evoked potential in a case of nitrous oxide abuse and recovery.
abstract: Pattern reversal visual evoked potentials were recorded in a dentist who had abused nitrous oxide while he showed neurologic impairment and during recovery. The latency of the major positive peak (P100) remained constant during both phases. However, the amplitude of this peak was markedly reduced during the stage of neurologic involvement, and increased during recovery after withdrawal. The clinical significance of this is discussed.
