Maternal depression can delay language development in babies
Washington: Depression during pregnancy can alter a crucial period of language development in babies, according to a new study.
Researchers at the University of British Columbia, Harvard University and the Child and Family Research Institute (CFRI) at BC Children’s Hospital found that treatment of maternal depression with serotonin reuptake inhibitors (SRIs) can accelerate babies’ ability to attune to the sounds and sights of their native language, while maternal depression untreated by SRIs may prolong the period of tuning.
“This study is among the first to show how maternal depression and its treatment can change the timing of language development in babies,” said Prof. Janet Werker of UBC’s Department of Psychology, the study’s senior author.
“At this point, we do not know if accelerating or delaying these milestones in development has lasting consequences on later language acquisition, or if alternate developmental pathways exist. We aim to explore these and other important questions in future studies,” she stated.
The study followed three groups of mothers – one being treated for depression with SRIs, one with depression not taking antidepressants and one with no symptoms of depression.
“These findings once again remind us that poor mental health during pregnancy is a major public health issue for mothers and their infants,” said co-author Dr. Tim Oberlander, a professor of developmental pediatrics at UBC and CFRI.
“Non-treatment is never an option. While some infants might be at risk, others may benefit from mother’s treatment with an antidepressant during their pregnancy. At this stage we are just not sure why some but not all infants are affected in the same way. It is really important that pregnant women discuss all treatment options with their physicians or midwives,” the researcher added.
Previous research by Werker has found that during the first months of life, babies rapidly attune to the language sounds they hear and the sights they see (movements in the face that accompany talking) of their native languages. After this foundational period of language recognition, babies begin focusing on acquiring their native tongues and effectively ignore other languages.
The current study suggests that this key developmental period – which typically ends between the ages of eight and nine months – can be accelerated or delayed, in some cases by several months.
In another recent study, Werker has found that this development period lasts longer for babies in bilingual households than in monolingual babies, particularly for the face recognition aspects of speech.
The study was published in the Proceedings of the National Academy of Sciences.
