I have to wonder if kids with poor executive function and inattentiveness/hyperactivity are more likely to be abused (hence higher ACEs), resulting in elevated risk for BPD.

I also have to wonder if the poor executive function and inattentiveness/hyperactivity are temporally preceded by increased ACEs—in other words, I wonder if ACEs might cause some of the ADHD-like features.

It’s also possible that neither is true (in which case both are probably just risk factors), or that both are true (in which case they all interrelate).

I’m not a researcher in developmental psychology, so I…really don’t know enough to answer my own queries.
