Neurologic correlates of osteogenesis imperfecta.

The neurologic status of ten patients with osteogenesis imperfecta (OI) was evaluated. Four patients with mild OI (type I) had normal neurologic findings and normal computed tomographic scans. Three of these four patients had macrocephaly. All six patients with severe OI (type III) had cortical atrophy on computed tomographic scan and three were also macrocephalic.
