title: [Time and depression in children and adolescents].
abstract: The existence of depression in young individuals has often been denied or at least underestimated particularly during adolescence, to the benefit of such other concepts as morosity, inherent in this period of life, and from which depression should be differentiated. Recent epidemiological investigations in the general population have revealed an approximate 2% and 10% prevalence of depression in the child and the adolescent, respectively. This considerable increase in morbidity is associated with a modification of the sex ratio: more boys are affected before puberty, more girls after puberty. In the present work we shall first deal with the semiology and comorbidity of depression as related with the developmental changes occurring in the child and the adolescent. Thus, several studies have shown that the DSM III criteria for affective disorders are consistently applicable to pre-puberty children and adolescents as well. However, depression in the pre-puberty children may be more ostentatious, manifesting itself by psychomotor agitation, somatic complaints and anxiety comorbidity of the type: Separation Anxiety Disorder and phobias. Depressed adolescents may exhibit more anhedonia, more depressive cognition, hypersomnia, weight variations, more alcohol or drug abuse and suicide attempts, and, in one third of them, greater coexistence of anxiety disorders or behavioural disorders. The course of depression at this age is now known, owing to catamnestic studies that proved methodologically satisfactory (we personally managed the follow-up of 75 depressed adolescents over an average 45 months). Depression in the child and the adolescent is not a benign affection, it is a long-lived, recurrent and disabling illness.(ABSTRACT TRUNCATED AT 250 WORDS)
