Women's posttraumatic stress symptoms and autism spectrum disorder in their children

- We examined the association between maternal lifetime PTSD symptoms and child's ASD.
- Maternal PTSD symptoms were associated with 2-3 times greater risk of child's ASD.
- Clinicians treating children with ASD should be aware of possible PTSD in mothers.
- Genetic studies should consider PTSD risk alleles in association with ASD.
