Neurologic Damage and Behavior Disorder in Rubella Children

A longitudinal study of 214 rubella-deaf children revealed a low incidence (10%) of neurologic damage among those with normal intelligence, but a high incidence (51%-70%) among those who were mentally retarded or blind. Neurologic damage in the eight deaf of normal intelligence included behavior disorder or Chronic Brain Syndrome in approximately one-third of this small group. Behavioral symptoms associated with these disorders are described.
