title: [Visual analysis of EEG in children with a cavum of the septum pellucidum].
abstract: OBJECTIVE
  It is possible that bioelectric activity of the both brain hemispheres is changed in children with a cavum of the spectrum pellucidum (CSP), a marker of brain dysgenesis. It could be connected probably with neuropsychological impairment in children with CSP.
  
  
  METHODS
  Visual analysis of EEG was done in 41 children with CSP aged 2 months to 17 years and in 32 children without CSP aged 3 months to 17 years. It induced 8 EEG curve pairs from each child, that means 328 pairs in CSP and 256 pairs without CSP children.
  
  
  METHODS
  EEG pattern was analysed by two physicians with an electro-encephalography license and data are a mean value of both analysis. Analysed were 40 minute EEG patterns, registered by 16 channels MedtronicDantec EEG PL-270 Video Option Aparat.
  
  
  RESULTS
  Brain bioelectric activity was significantly more often immature and basic activity irregular in children with CSP than in the group without CSP. Asymmetry of frequency and amplitude and slow activity were also significantly more often observed in children with CSP. Abnormal graphoelements were also significantly more often disclosed in children with CSP.
  
  
  CONCLUSIONS
  Visual analysis disclosed significant differences of EEG pattern in children with and without CSP. For identification of EEG from patient with CSP the quantitative method of analysis is necessary.
