Coeliac disease (CD) occasionally presents solely with neuropsychiatric symptoms and may predispose to mental and behavioural disorders. This study screened new adolescent psychiatric outpatients (n = 140) in the Department of Adolescent Psychiatry of the Hospital for Children and Adolescents, Helsinki, using immunoglobulin A antibody to tissue transglutaminase. The prevalence rate of CD was found to be 1 in 140.
The results do not suggest that undetected CD is markedly overrepresented among adolescent psychiatric outpatients.
