1. To investigate whether abnormalities in objective neurophysiologic measures are observable in @entity1 with probable dissociative generalized @entity2730 , the @entity3493 and N100 event-related potentials were evaluated in six such @entity1 in both acute stage and after recovery from @entity2730 . Findings were compared with those in 12 age- and gender-matched healthy subjects. 2. While latencies did not differ from those of control subjects, @entity3493 amplitudes in acute-stage recordings were lower than those in controls. Repeated recordings in the @entity1 showed a significant increase in @entity3493 amplitude after recovery from @entity2730 . 3. Amplitude and latency of N100 did not differ between the @entity1 and control groups, nor changed significantly after retrieval of memory. 4. These findings suggest that some unknown biological and/or psychologic mechanisms that cause retrograde autobiographic @entity2730 may impair cognitive function as reflected in an objective neurophysiologic measure such as the @entity3493 .
