[Mental development of children suffering from chronic insufficiency of digestion under dietary therapy for several years].

73 children suffering from malabsorption, galactosaemia, and fructose intolerance had been treated for many years. They were investigated psychologically in regard of their mental development. The nutritional condition was very bad before and in the first time of therapy, nevertheless a normal intelligence and an inconspicuous social behaviour was founded. The considerable retardation of the bodily and intellectual development was not sufficiently compensated in the preschool-age. But there is a better arrangement during school-age.
