Abstract
A series of 17 monozygotic twins discordant for schizophrenia was studied intensively at the National Institute of Mental Health between 1963 and 1967. Sixteen pairs were interviewed a mean of 7.8 years after original admission.It was found that one pair is now concordant for schizophrenia, three previously healthy co-twins show new psychopathology of a possibly schizophrenic nature, and 12 twin pairs remain stably discordant.Keywords
