Ah. This.
Now you speak close to the heart of Princess's matter. Brain matter that is.
Traumatic / closed head brain injury and its attendant sequelae, often long term if not lifelong. (The jury is still out, so to speak, on that one. Many of us are "not dead yet" for conclusive results post mortem. )

As my "Good Doctors" along the Princess's way since first TBI ~ '92-'93, second in 2008 --- say: "It is really difficult to say. It's such a chicken and the egg thing with all the aggravating and mitigating factors."

I hope to post more here once I've gathered my thoughts. Meanwhile, I hope that we may see more join in this discussion with experience and perspectives shared.

I would be interested to know who and how many here on the forum have experienced brain trauma. And what came first, the TBI/CHI/ABI, or the so-called pathopsychological labeling/diagnosing as "MI"? Again, the chicken and egg analogy applies.

Thank you again, glok.
