The frequency-amplitude gradient in the sleep EEG of children and its diagnostic significance

OBJECTIVE: 1014 EEGs of children in the 3-months to 12-years age group were obtained during sleep with the purpose of assessing the frequency and amplitude gradient (FAG) its absence thought to be an indicator of neurological disorder. METHOD: FAG findings were divided into present/absent. The neuro...

METHOD: FAG findings were divided into present/absent. The neurological findings were classified according to the presence (abnormal neurological finding-ANF) or absence (normal neurological finding-NNF) of neurological disorder. The association and significance between FAG and neurological findings was determined by prevalence ration (PR) and chi-square test (chi2). RESULTS: FAG showed a characteristic distributions of voltage output during non-REM sleep, stage II, in the 3-months to 5-years age group with NNF. The PR and the chi2 test demonstrated a strong association between FAG absent and ANF. CONCLUSION: FAG is an age-dependent EEG sleep parameter and absence of FAG in the 3-months to 5-years age group is highly suggestive of neurological disorder. OBJETIVO: Estudaram-se 1014 EEG de crianças na faixa etária de 3 meses a 12 anos de idade obtidos em sono com o objetivo de avaliar o gradiente de freqüência-amplitude (GFA) ausente como possível indicador de comprometimento neurológico. MÉTODO: O GFA foi caracterizado: 1 - presente; 2 - ausente. O padrão neurológico foi classificado segundo a presença ou ausência de comprometimento neurológico em padrão neurológico anormal (PNA) e normal (PNN), respectivamente. RESULTADOS: O GFA mostrou-se um parâmetro EEG próprio da criança em sono na faixa etária dos 3 meses aos 5 anos de idade e com PNN. O teste do qui quadrado e a razão de prevalência mostraram relação altamente significativa para o GFA ausente, e o PNA. CONCLUSÃO: O GFA é um parâmetro EEG do sono idade-dependente e sua ausência na faixa etária dos 3 meses aos cinco anos é altamente sugestivo de comprometimento neurológico. 2017-12-07T04:46:15Z 2017-12-07T04:46:15Z 2007 Artigo Arq.
