The double frequency and amplitud gradient absent in the EEG during the sleep as a possible indication of children's compromise

THE DOUBLE FREQUENCY AND AMPLITUD GRADIENT ABSENT IN THE EEG DURING THE SLEEP AS A POSSIBLE INDICATION OF CHILDREN'S COMPROMISE (ABSTRACT)^*. DISSERTATION. BRASÍLIA, 2000.

Study on 200 EEGs of children with ages ranging from 3 months to 12 years old, obtained in sleep, in order to evaluate the frequency and amplitude double gradient (FADG) as possible indicator of neurological compromise.

Using as base the visual analysis, we have defined the FADG into two categories: FADG present; FADG absent.

The correlation of the FADG with the neurological pattern, showed that 73.1% of children with normal neurologial pattern (NNP) had the FADG present, and 26.9% had the FADG. In the 62 EEGs of children with altered neurological pattern (ANP), 14.5% had the FADG present and 85.5% had the FADG absent. The qui square test, showed a highly significant relation for the absent FADG, and the anormal neurological pattern.

The FADG is parameter EEG depending of the age. The FADG should be valued in the interpretation criteria of the EEG of children's sleep.

KEY WORDS: EEG, double gradient, childhood.
