A complex and multiaspects study of the high cerebral function--speech, gnosis, praxis, gesture and mimics has been coducted on 98 children with proved speech defects--alalia, dyslalia, dysgraphia, dyslexia and stammering. In high percentage of the children various focal neurological signs have been established (so called soft neurological symptoms). Very high was the percentage of the children with visual-space defects. Rhythm gnosis and praxis suffered mostly in children with motor alalia. The tests for gesture and mimics prevailed. The unified mechanism of the disturbed development of the speech and the other high cerebral functions were discussed.
