Abstract: Modern electroencephalography is largely mathematical method. According to many researchers, “basic” mathematical method is a method of EEG spectral analysis. We also used a coherent analysis of the EEG. Several authors recommend routine electroencephalography, EEG monitoring: with perinatal asphyxia, with seizures, tremor, infants with mechanical ventilation, in children with meningitis and malformations, in babies with heart defects or congenital diaphragmatic hernia, in children with severe hypoglycemia or metabolic diseases (Hellstom-Westas L. et al., 2008).
The mathematical EEG in neuropsychiatric disorders early age (Perinatal encephalopathy (HIE), febrile seizures, affective-respiratory paroxysms) confirms the clinical, morphological and neuroimaging data on cortical lesions in the areas of regional cortical blood flow between the anterior, middle and posterior cerebral arteries. The results show a delay electrogenesis EEG during wakefulness and sleep pattern maturation that are associated with neuronal loss. In addition, the visual and mathematical analysis of EEG builds neuro-psychiatric disorders early age, as if in a hierarchy. When HIE changes are expressed minimally (22%), with the affective-respiratory paroxysms EEG changes are expressed in moderate (one-third of the cases), with febrile seizures (more than half the time) are expressed to the maximum.

Key words: mathematical EEG, spectral analysis EEG, coherent analysis EEG, Perinatal encephalopathy (HIE), febrile seizures, affective-respiratory paroxysms
