Disorders of failing academically children represent an important part of child psychiatrists' occupation. Various reasons are responsible for these disorders. But the role of inhibition seems to be major. Authors study cases of 66 children, as outpatients, who failed academically. Incidence of inhibition is about 26.9%. Authors analyse demographic data, personal and familial history of these children, age of beginning of disorders and their symptomatic aspects, and last, clinical categories in which some of these disorders can be classified. Thus early detection of inhibition disorders occurs as an absolute necessity.
