Childhood Motor Coordination and Adult Schizophrenia

Method: A standardized childhood neu­ rological examination was administered to a sample of 265 Danish children in 1972, when participants were 10–13 years old. Adult diagnostic information was available for 244 members of the sample. Participants fell into three groups: children whose mothers or fa­ thers had a psychiatric hospital diagnosis of schizophrenia (N=94); children who had at least one parent with a psychiatric record of hospitalization for a nonpsy­ chotic disorder (N=84); and children with no parental records of psychiatric hospi­ talization (N=66). Psychiatric outcomes of the offspring were assessed through psy­ chiatric interviews in 1992 when partici­ pants were 31–33 years of age, as well as through a scan of national psychiatric reg­ isters completed in May 2007.
