Similar Assertions

If a mom is exposed to certain chemicals during pregnancy, her son might show slightly more ADHD-like behaviors by age 2 to 4, but the link isn’t strong enough to be sure — and it doesn’t seem to affect girls the same way.

Boys and girls react differently to mom's exposure to certain chemicals during pregnancy when it comes to early signs of ADHD. Girls seem to have fewer symptoms linked to some lighter chemicals, while boys show a slight increase in symptoms with heavier ones, though it's not strong.
