Maternal Depression Linked to Higher Autism Risk in Daughters | Haidoc

A new study has found that perinatal depression – depression occurring during pregnancy or shortly after childbirth – may increase the risk of autistic traits in daughters by as much as ninefold. The research, reported by the Korean news outlet Daum, examined the correlation between maternal psychological stress during and after pregnancy and the development of autism-related traits in children aged two to three years.

Researchers assessed maternal depression levels using the K6 scale for psychological stress during early and mid-pregnancy (0-15 weeks and 16-27 weeks respectively) and the EPDS (Edinburgh Postnatal Depression Scale) four to five weeks postpartum. They then measured autistic traits in their children using the Tokyo Autistic Behavior Scale (TABS). The findings indicate a significant link between maternal depression and the emergence of these traits, particularly in female children.

While autism spectrum disorder (ASD) is generally understood to be more frequently diagnosed in males, this study highlights a potential vulnerability in daughters of mothers experiencing perinatal depression. The research does not establish a causal relationship, but rather demonstrates a statistically significant association.

Treatment options for depression during pregnancy include counseling and both pharmacological and non-pharmacological interventions, according to Seoul Asan Hospital. Counseling can equip women with coping mechanisms for depression, and medication may be prescribed by a physician if symptoms are severe or unresponsive to counseling. We see critical for expectant mothers experiencing symptoms such as persistent sadness, loss of interest in activities, irritability, feelings of guilt or worthlessness, unexplained crying, restlessness, fatigue, changes in sleep or appetite, social withdrawal, difficulty concentrating, or thoughts of harming themselves or their baby to seek professional aid. Ignoring these symptoms and attributing them to normal pregnancy changes can be detrimental.

The study underscores the importance of screening and addressing maternal mental health throughout pregnancy and the postpartum period. Experts emphasize the need for open communication between expectant mothers and their healthcare providers regarding any emotional or psychological difficulties they may be experiencing.

Further research is needed to fully understand the mechanisms underlying this association and to develop targeted interventions to mitigate the risk. The study does not indicate whether similar risks exist for sons of mothers experiencing perinatal depression, nor does it explore the potential long-term effects of these autistic traits.
