Does the mental health of parents affect the health of the child to be born?
Pregnancy is a period of profound transformation, marked by physical, emotional, and psychological changes. For some women, this time can be accompanied by stress and anxiety, which may affect not only their own mental health but also that of their unborn child.
Psychoanalyst Daniel Stern introduced the concept of “psychic transparency” to describe a state of heightened emotional vulnerability and increased receptivity to unconscious thoughts and feelings during pregnancy. This vulnerability makes pregnant women more sensitive to stressors and negative emotions, with potential consequences for both maternal and fetal mental health. Appropriate psychological support therefore becomes essential for expectant mothers experiencing psychological difficulties. The central question remains: how does parental mental health shape the developmental trajectory of the unborn child?
A major scientific study examines different forms of prenatal stress in pregnant women and their impact on neurodevelopment. The research identifies three distinct profiles: a healthy group, a psychologically stressed group, and a physically stressed group. The findings show that prenatal stress can influence the baby’s sex at birth, birth complications, and the development of the fetal central nervous system.
Another study focusing on microRNAs shows that disruptions in their maturation may have significant implications for understanding various diseases, including cancers and neurodegenerative disorders. MicroRNAs are non‑coding RNA molecules that play a crucial role in gene regulation.
Genomic imprinting (an epigenetic mechanism in which the expression of certain genes depends on their parental origin) has considerable effects on future disease pathways. In humans, around 100 to 200 genes are subject to imprinting, influencing fetal growth and placental development. Dysfunctions in this mechanism can lead to genetic syndromes, developmental abnormalities, and certain cancers.
Epigenetic abnormalities are associated with growth syndromes, some cancers, neurodegenerative diseases, and metabolic disorders such as diabetes and obesity.
Genomic imprinting therefore plays a fundamental role in normal development and overall health. In‑depth longitudinal research is needed to better understand and prevent these conditions, while also assessing parental mental health. At the same time, providing appropriate psychological support to pregnant women helps mitigate the negative effects of prenatal stress. Such support allows clinicians to detect and treat mental health issues like anxiety and depression during pregnancy, fostering healthy and harmonious development for both mother and child.
