Tourette syndrome is a neuropsychiatric syndrome characterized by motor and vocal tics with further co-morbidities, e.g. obsessive–compulsive disorder and attention deficit hyperactivity disorder. There is only a single prior case report in pregnancy in addition to a postal questionnaire study including 10 pregnancies. In a series of 11 pregnancies in patients assessed by the authors, there were no adverse effects on the pregnancy, although some obstetricians were unduly concerned. There was no consistent effect on the severity of the tics, although in some women there seemed to be a significant improvement during pregnancy.
