Study suggests PBDEs fed to mother mice can cause brain modifications in offspring

Penta-BDE was fed to mother mice at 0.4 mg/kg body weight per day (orders of magnitude higher than general human population exposure). PBDEs were transferred to offspring both in utero and in lactation and resulted in modifications in brain chemistry and in behaviour of offspring, including modifying social recognition and object memory, but not impacting anxiety or depressive behaviour. Media coverage suggests that such changes are comparable to symptoms of ASD (autism spectrum disorder).
