The stages of development of infant cerebral palsy (ICP) in 300 patients during the childdhood period, beginning from the neonate period, are presented in this article. Clinico-morphological analysis has been realized in 35 cases with the mortal outcome. It has been established, that combination of the following signs is the morphological basis of ICP: dysontogenetic development of the separate structures of the brain, cerebrovascular disturbances, dystrophic changes of the structural elements of the brain and in number of cases - of the focal inflammation of the brain matter, predominantly in the region of walls of the lateral ventricle of the brain.In parallel with the destructive changes in the brain the compensatory restorative processses have been also observed.
