Facial Clefting and Psychiatric Diseases: A Follow-Up of the Danish 1936–1987 Facial Cleft Cohort

Abstract

The risk of hospitalized mental disorders in general is increased in patients with CP but not to any substantial degree in patients with CL(P). Both groups had an increased risk of mental retardation and substance abuse, but the risk for schizophrenia or bipolar illness was not statistically significantly increased, compared with the background population. Further, our data provide no evidence that the psychosocial stressors associated with CL(P) and its treatment have any substantial impact on the risk for hospitalized mental illness.
