[Depersonalization disorders in schizophrenic children].

The paper is concerned with a study of age variants of depersonalizational disturbances in schizophrenia children of early preschool age and preschool age. Depersonalizational disorders proper were found in 25 cases, disturbance of the self-conscious and its deterioration in 59, retardation in the development of the self-conscious formation--in 32 cases. Depersonalizational disturbances appear in children over 3 years, i.e. following the first physiological age crises. The following types of depersonalizational disturbances were distinquished: 1) moderately expressed loss of the self-conscious with disorders in the differentiation of the "I" from the associates; 2) a deeper disorder of the "I" with a substitution of the personal "I", by another "I"; 3) phenomena of estrangement of the self-conscious with a state similar to the splitting of the self-conscious, up to the appearance of the phenomena of a twin; 4) a change of the self-conscious expressed in a pathological play transformation and a substitution of the "I" by another "I", or a splitting of the self-conscious into the syndrome of play transformation near to a delusional; 5) derealization; 6) loss of the conscious of personal sex; 7) estrangement of the conscious of personal actions; 8) disturbance of self-conscious of a physical whole; 9) disturbance of the self-conscious in a deep depression with a loss of "I-vitality" appearance near to "anaesthesia psychica dolorosa" and "nihilistic delusions"; 10) loss of "I" conscious and regress of speech, motor activity, behaviour; 11) retardation in the formation of "I" conscious.
