A groundbreaking study from the Institute for Clinical Evaluative Sciences (ICES) and the University of Toronto has identified a significant link between a history of concussion and the risk of severe mental health issues in new mothers. The research indicates that individuals with a past concussion are 25% more likely to experience mental health challenges after childbirth, underscoring the importance of early identification and long-term support in prenatal care.
Led by Samantha Krueger, a registered midwife and PhD candidate in Health Research Methodology at McMaster University, the study analyzed data from over 750,000 birthing people in Ontario between 2007 and 2017, tracking mental health outcomes for up to 14 years post-delivery. The results revealed that 11% of those with a history of concussion developed severe maternal mental illness, compared to 7% of those without a history of concussion. This association was particularly pronounced among individuals without a prior mental health diagnosis, with a 33% increased risk of severe maternal mental illness following a concussion.
Krueger emphasizes the significance of these findings, particularly for individuals with no prior mental health history. “Concussion may be an important but overlooked risk factor during pregnancy and postpartum care,” she notes. The physical and emotional demands of parenting, such as sleep deprivation and stress, can exacerbate concussion-related challenges, potentially raising the risk of mental health issues over time.
Senior author Dr. Hilary Brown, an Adjunct Scientist at ICES and Associate Professor at the University of Toronto Scarborough, explains that cognitive impairments, sensitivities to light and noise, and the stress of caring for a newborn can all intensify concussion symptoms. Given the biological links between brain injury and mental illness, routine antenatal screening for concussion history and the provision of mental health resources are advocated by the researchers.
The study’s findings point to a critical need for healthcare providers to consider concussion history when supporting new parents. Early identification and long-term support could significantly impact the prevention of serious psychiatric outcomes. The researchers hope their findings will encourage healthcare providers and policymakers to prioritize concussion prevention in people of reproductive age and ensure adequate mental health resources for new parents with concussion histories.
Conclusion
The study from ICES and the University of Toronto contributes to the growing body of evidence that reproductive care should incorporate neurological and mental health factors. By addressing the full spectrum of risks faced by birthing people, including the impact of concussion history on maternal mental health, healthcare providers can better support new parents and contribute to better outcomes for both mothers and children.
