Differing from the previous view of the development of diseases, the past few centuries research has recognised the developmental nature of diseases and the impact of prenatal factors. Different personality disorders have also been linked to adverse prenatal factors. Recent studies have focused on the effects of risk factors such as being born premature or small for gestational age, being exposed to prenatal stress or teratogens, and maternal nutrition during gestation. The effects of these factors on later personality disorders have differed according to the study and the methods it has used, but there seems to be a rather consistent connection between prenatal adversity and personality disorders. The most probable explanation for this is that an adverse prenatal environment affects the fetus’s neurodevelopment, causing a metaplastic state that exposes the individual to later adversity.
