Children with preschool minor neurodevelopmental disorders. V: Neurodevelopmental profiles at age 13.

A cohort of children diagnosed at age seven as suffering from deficits in attention, motor control and perception was compared at age 13 with a group of children without such problems. More than two-thirds of the index children no longer had any clearly detectable motor problems at 13, but they still had significantly prolonged complex reaction times. These results suggest that children with these deficits in the early school years have a fair biological prognosis by the early teen years.
