Maternal Stress Linked to Autism Risk
6 Feb
Summary
- Perinatal depression in mothers is linked to autistic traits in children.
- Female offspring of stressed mice showed autism-like behaviors.
- Supporting maternal mental health is critical for child development outcomes.
Maternal stress around the time of pregnancy may heighten the risk of autism in children, according to a recent study. Researchers observed that women experiencing perinatal depression were more likely to have children exhibiting autistic traits.
This effect was particularly noted in girls, who also showed a tendency towards lower birth weight and weaker mother-infant bonds. However, boys, irrespective of their mother's mental status, displayed more autistic-like traits.
The study's findings underscore the necessity of early identification and support for mothers with perinatal depression. Scientists analyzed data from over 23,000 mother-child pairs to establish these links.
To further investigate, a stress model in mice revealed that stressed mothers had lower oxytocin levels, a hormone crucial for bonding. Their female offspring exhibited autism-like behaviors and reduced social awareness.
Previous research has also indicated a potential link between antidepressant use during pregnancy and an increased risk of autism. Experts emphasize the importance of screening and supporting maternal mental health throughout pregnancy.
