Two types of heterogeneity have been identified in ...

[4] [6] Environmental risk factors are many, and include pregnancy complications, prenatal stress and nutrition, and adverse childhood experiences. An environmental risk factor may act alone or in combination with ...
Instead of studying one brain region, studying large scale brain networks is another approach to understanding psychiatric and neurological disorders, [161] supported by recent research that has shown that multiple brain regions are involved in these disorders. Understanding the disruptions in these networks may provide important insights into ...
The genetic influences of post-traumatic stress disorder (PTSD) are not understood well due to the limitations of any genetic study of mental illness; in that, it cannot be ethically induced in selected groups. Because of this, all studies must use naturally occurring groups with genetic similarities and differences, thus the amount of data is ...
