A family is presented in which 5 of 7 siblings and 10 of 17 members of the last 2 generations have had psychotic episodes. At least 5 members have experienced their mental illness in connection with childbirth, and 2 in connection with back injury. It is suggested that our interpretation does not rule out a hereditary or somatic concept.
