[Psychological features of treated phenylketonuric patients of preschool age].

Psychological features of 6 children with phenylketonuria were studied. The children were of 5--7 years of age and received special dietetic management. Regular studies of the "learning type" were used as a method of dynamic psychological examination. Despite the fact that the children were of different age and intellectual level, showing different behavior pattern and individual personality traits, all of them had some mental features in common. These features included peculiarities of the emotional-evolutional sphere, disturbed attention and working capacity, local spatial disorders and a weakly developed internal plan of action. These mental traits should be taken into consideration during pedagogical correction of defects in treated phenulketonuric children.
