title: [Cognitive functioning in adolescent depression].
abstract: In childhood and adolescent depression, the interaction between cognitive and emotional disorders is particularly evident: intellectual dysfunctioning often accompanies and integrates the clinical symptomatology. The studies on cognitive functioning have focused their attention on basic cognitive abilities; relatively fewer studies have analyzed other dimensions, such as logical reasoning. Furthermore, most studies have compared depressed patients to normal controls; this methodology tends to obscure the specific effect depression may have on cognitive functioning. The aim of our study is to analyze whether specific patterns of cognitive organization underlie adolescent depressive disorders. Cognitive functioning was assessed both with psychometric tests (WISC-R) and Piagetian logical reasoning tasks (Longeot Logical Thought Scale). The performance of depressed adolescents was compared to that of neurotic patients without depressive symptomatology. To evaluate the course of cognitive organization in relation to depressive symptomatology, some of our patients were studied in follow-up. Thirty-eight adolescents admitted to our Institute participated in the study. The experimental group consisted of 24 depressed adolescents; sixteen subjects were classified as neurotic depressives, eight were diagnosed as depressive personality disorder. The control group consisted of 14 subjects diagnosed as neurotic without depression. At the WISC-R the performance of depressed and controls adolescents were compared in: Full Scale IQ, Verbal and Performance IQ, Verbal-Performance discrepancy; single subtest scores; Bannatyne's four categories. Statistical analyses did not yield any significant differences between groups for any of the WISC-R measures. At the Logical Thought Scale Full Scale scores of the experimental group were significantly lower than controls'.(ABSTRACT TRUNCATED AT 250 WORDS)
