I am trying to discern whether, in the brain (structure & function) of people with bipolar disorder/MDD/schizophrenia who experienced childhood trauma, there are:
1. already differences in children's brain structure & function that trauma further modifies and the person develops a mental illness OR (genetics first then trauma)
2. trauma changes the structure and function of the brain that the child's genetics further modifies and the person develops a mental illness (trauma first then genetics)
Has anyone researched this & if so, can you please share your findings or references you know of?
