Genomics will play a significant role in determining risk because vulnerability to potential disruption in central nervous system development may be a factor in determining the development of the brain in utero. We know, for example, that prenatal stress affects neuromodulation in the brain, and that vulnerability to disruption will be variable from patient to patient. Prospective studies where we not only quantify what medicines women are taking and the severity of psychiatric illness, but also vulnerability to central nervous system disruption, if any, at the level of the genome will be a critical missing piece for future investigators.
Even similar exposure to medicine and psychiatric disorders may have variable effects on the developing brain. If we can identify that variability at the level of the genome, then we will be able to create a refined model of risk that will dictate personalized medicine with respect to reproductive psychopharmacology.
