title: [The influence of cognitive-behavioral therapy on the P300 potential in children with psychogenic nonepileptic seizures and tension headache].
abstract: Explaining associations between neurophysiological and neuropsychological parameteres in children and improving the measurement methods would lead to a better understanding of the pathogenesis and course of psychosomatic disease. Goal: clinical assessment of the efficacy of cognitive-behavioral therapy in the treatment of psychogenic no- nepileptic seizures and tension type headaches in children. Determining the influence of cognitive behavioral therapy on the cognitive P300 potential and whether P300 parameters in children correlate with neuropsychological parameters.
  
  
  METHODS
  20 children with nonepileptic psychogenic seizures and 30 children with tension type headaches, aged 11.3 - 17.11 years. The final diagnosis was made in the Paediatric Neurology Clinic. The P300 examination was performed before/after therapy, with/without hyperventilation. A fixed structure therapy was implemented (10 sessions, 90 minutes each), during two weeks of hospitalization or in an outpatient clinic (9 children with tension type headache). The psychological assessment comprised of temperament questionnaires, auditory and visual memory trials, executive function and attention trials, and in some cases also intelligence testing.
  
  
  RESULTS
  More significant correlations were found in children with psychogenic seizures: attention parameters correlated negatively with reaction time, and this correlation tended to fade in the second examination, after psychotherapy. In children with tension type headache a statistically insignificant tendency was found of a positive correlation between those parameters. Medium P300 parameteres in this group were better. In 17/20 of children with psychogenic seizures a clinical improvement was observed, in 3 children the symptoms persisted in a 6 month follow up, but of a lower frequency. In 11/27 of chil- dren with tension headache the symptoms persisted, also with a lower frequency.
  
  
  CONCLUSIONS
  cognitive-behavioral therapy is effective in the reduction of symptoms in many cases of psychogenic seizures and chronic tension type headache.
