Comparison group was composed from 39 children of similar age who were registered for observation by pediatric polyclinics neurologists and were rehabilitated. Results: 2 algorithms formed as decision trees, that were built using multivariate analysis methods were suggested and can be used in pediatric polyclinics for children with ICP formation threatening detection. Conclusion: the ICP formation can be forecasted in 93% of cases wrt prematurely born children with convulsive and hypertensive-hydrocephalic syndromes in aggregate with periventricular leukomalacia
