[Cerebral syndromes in premature children].

Cerebral disturbances observed in premature infants are analyzed. These disturbances are a consequence of developmental slowdown and are associated with the pathological immaturity of the brain structures. On condition an active pathogenetic therapy is given these disturbances may gradually regress. On the basis of long-term observations of 600 prematurely born infants the authors describe the following clinical syndromes: muscular hypotonicity lasting up to 4-5 months and followed with a rise of the tone; the syndrome of "paretic hands" observed during the first two months of life; a hypertensive-hydrocephalic syndrome combined with a rise of the neuro-reflectory excitability; the syndrome of psychomotor development retardation followed at an age of over 1.5 to 2 years by complete recovery or minimal cerebral insufficiency with belated development of motor speech and neurosis-like reactions.
