There is however a possible role for stress-induced maternal inflammation whereby the up-regulation of pro-inflammatory placental genes results in changes in the developing fetal immune system.
Researchers are actively studying how to reduce the impact of these occurrences, not only for expectant mothers and children, but also for society as a whole.
Although epigenetic and genetic factors play a role in the heritability of neuropsychiatric disorders, the relationship and mechanisms that underpin it are likely to be multifactorial.

Journal of Child Psychology and Psychiatry ;48 Timing is everything, especially for the effects of prenatal maternal stress PNMS. When is a fetus most susceptible to prenatal maternal stress. Surprising results from the Suzanne King's research team on PNMSindicate that objective stress has more of an affect on fetal development than subjective stress.
Diverse microbial communities in the maternal host are essential in modifying the immune responses, CNS physiology and behavior as well as regulating the neuroendocrine system, including the HPA axis.
In a stressful environment it may have been adaptive for our ancestors to have children who were more vigilant anxious or with readily distracted attention ADHDand possibly with more rapid motor development.

At week 10, the embryo becomes a fetus and it begins to move.
Psychosocial stress can cause disturbances in the maternal GBA as well as also disturbing other microbial communities in the human body such as the vaginal microbiota. People conceived during the Dutch famine have altered regulation of growth genes December 3, Individuals conceived in the severe Dutch Famine, also called the Hunger Winter, may have adjusted to this horrendous period of World War II by making adaptations to how active their DNA is.

This topic aims to provide greater understanding of the potential effects of maternal stress on the. However, there are many inconsistent results and the impact, if any, of maternal stress and inflammation on programming of depression in the offspring is still unclear.
The mechanism of prenatal depression and the risk of the offspring developing depression may be through cortisol-induced changes to the HPA axis in the fetus . The impact of drugs on the fetus during the pregnancy depends on the timing of use, dosage, level of prenatal nutrition, and individual differences among mothers, some of which may be heritable.
The impact on the unborn child depends on the stage of prenatal development in which it occurs, how severe a condition is and how long it lasts.
