Background:
Adverse pregnancy and neonatal outcomes in women with Tourette syndrome or chronic tic disorder (TS/CTD) have not been systematically studied. This Swedish population-based study investigated associations between maternal TS/CTD and pregnancy, delivery, and neonatal outcomes.
Methods:
We included all singleton births at ≥22 weeks between 2001 and 2021. Each pregnancy with TS/CTD was matched on mother's age and delivery year with up to 10 pregnancies without TS/CTD. Crude and adjusted relative risks were estimated using Poisson log-linear regressions.
Results:
We compared 581 pregnancies in women with TS/CTD to 5777 matched unexposed pregnancies. Maternal TS/CTD was associated with significantly increased risks of gestational diabetes, and elective and emergency cesarean section. Neonates of women with TS/CTD showed no increased risks of adverse neonatal outcomes.
Conclusions:
Maternal TS/CTD is associated with increased risk of some adverse pregnancy and delivery outcomes, but not with adverse neonatal outcomes. Enhanced maternal care for women with TS/CTD is warranted. © 2025 The Author(s).

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
