A test of the immunoreactive theory for the origin of neurodevelopmental disorders in the offspring of women with immune disorder.
Gualtieri and Hicks (1985) proposed that male vulnerability for neurodevelopmental disorders (NDs) was partially due to intrauterine immune attack of the fetus. One group of mothers with heightened immunoreactivity might be women with immune disorder. This was tested within an epidemiological sample of 17,283 mother/child pairs. Maternal immune disorders considered were ulcerative colitis or asthma. NDs in the child included: cerebral palsy, mental retardation, seizures, articulation disorder, reading, or arithmetic disability, verbal or performance aptitude deficits, and attention deficit disorder. Unlike prior studies, we controlled for demographic perinatal variables that might confound interpretation of the data. Results indicated that immune dysfunction in the mother, be it autoimmune (ulcerative colitis) or defensive (asthma) was not associated with an increased incidence of any NDs in the offspring, but mothers with ulcerative colitis did have a disproportionate number of offspring who were non-right handed. Few variables discriminated between the children of ulcerative colitis mothers who became right handed when compared to those who did not. We suggest that a) only certain maternal autoimmune disorders such as systemic lupus erythematosus (but not ulcerative colitis or asthma) elevate the risk of intrauterine immune attack and b) the elevated rate of non-right handed offspring among ulcerative colitis mothers was not an instance of immune attack but instead represents some kind of genetic association.
