[Perinatal encephalopathy: leading disease of children in the 1st year of life and its medical-social consequences].

The morbidity of infants during the first year of life as regards individual states developing in the perinatal period varies in some towns within 100-200/1000. One of the major conditions of this class is perinatal encephalopathy. The total morbidity among infants of the first year of life suffering from perinatal encephalopathy is two times higher than that of infants without abnormalities of the central nervous system. At the age of 4 the morbidity values in these two groups are 3230.9 and 2194.2/1000, respectively.
