Right hemisphere involvement in learning disability, attention deficit disorder, and childhood major depressive disorder.

Learning disability, attentional disorder and childhood major depression are frequent diagnoses in children with behavioral disturbances and impaired school performance. All three disorders are associated with right cerebral hemisphere dysfunction. Anatomical disturbance of right hemisphere function results in learning disability and/or attentional disorder. The physiological disturbance of right hemisphere function produced by a major depressive episode results in additional learning disability and/or attentional disorder.
