[Syndrome forms of complicated oligophrenia (Rubinstein-Taybi and Noonan syndromes)]

The article presents the results of clinicogenetic studies of two syndromal forms of complicated oligophrenia featuring the intellectual underdevelopment combined with apraxic cortical dysarthria, hypogenitalism and multiple dysontogenies. Psychopathological structure of these syndromal forms of complicated oligophrenia are given. This is of major importance for diagnostic, medical and psycho-pedagogical correction. The questions of genetic heterogeneity of the syndromes are discussed.
