abstract

  • Summary: The relation between hyperventilation (HV)‐induced high‐amplitude rhythmical slowing (HIHARS) and altered responsiveness without generalized spike and wave activity has not been clearly defined. To test whether altered responsiveness is a nonspecific physiologic response rather than a symptom of generalized epilepsy, we assessed verbal recall ability and motor response testing in 12 healthy nonepileptic children (mean age 9.6 years). Both tasks were administered as a baseline before HV, during HV but before onset of EEG slowing, and during HIHARS. Verbal recall and motor responsiveness remained unchanged during baseline and HV before onset of slowing. During HIHARS, all children exhibited impaired verbal recall (p<0·005) and 8 of 12 failed to respond to repeated auditory clicks (p < 0·005). Our findings indicate that in a normal setting, responsiveness may be impaired during HV in healthy nonepileptic children. Copyright © 1994, Wiley Blackwell. All rights reserved
