Cognitive functioning in adolescents with schizophrenia spectrum disorders.
In contrast to studies of cognitive functioning in adults with schizophrenia, there has been a relative paucity of studies assessing adolescents with schizophrenia. We investigated cognitive functioning in 22 adolescents with schizophrenia spectrum disorders compared with 30 healthy adolescents. The patient group demonstrated impaired performance on all of the functions investigated except sustained attention. Against the background of this broad impairment, executive function and psychomotor speed were the most impaired, sustained attention was spared, while preattentional processing, early visual information processing, visual long-term memory, auditory short-term memory and working memory emerged as relative deficits. The study shows that adolescents with schizophrenia spectrum disorders demonstrate a similar pattern of cognitive functioning to adults in all areas, except sustained attention.
