Alright well I guess I to me it makes sense I have some problems going on in the brain. I'd agree its not only about chemicals and brain changes there is probably much more than that. However especially when it comes to my having developed PTSD symptoms my functioning got noticably worse....as in my brain did not work the same, at least that is how it feels and it seems I am not too far off based on studies of changes in the brain that take place if you develop PTSD.

I guess to me it matters because I had more cognitive ability before the PTSD...as for my depression and anxiety, that's been around since I was a child I think it could be related to environmental/social factors....due to being treated badly for being 'weird' due to being on the autism spectrum which causes defects of its own...I suppose there are some useful traits that exist within it, but there's some really debilitating aspects.
