Hi and welcome to NeuroTalk.

I’m on the “other side”; I’m the TBI survivor, so my thoughts will be from that side of the experience and what I have learned about recovery from TBI.

Being argumentative and other forms of disinhibition are not uncommon, but after two years I would have expected some improvement. It’s concerning that he refuses to follow doctors and therapists advice. My experience was that it was the doing the mental exercises that helped my recovery. I did repeat myself often, and I just asked my wife and others around me to let me know when I was doing that. That way I began the process of consciously trying to remember what I said and did.

A little more information about his injury would be useful. Was his injury a single mTBI (concussion), multiple concussions, or some other injury? Is he seeing any therapists such as occupational or speech?

If you have insurance I’d suggest a neuropsychological evaluation from a clinical neuropsychologist if he hasn’t yet had one. That can help identify specific deficit areas and tailor therapies toward resolving them. This of course assumes he is willing to be evaluated and to follow up with the therapies.

The loss of interest in sex could be physical, psychological, or a combination, depending on his injury. I’d suggest as part of his next physical exam they test his testosterone level. Mine plummeted after my accident, and for men, low T will reduce libido and can contribute to ED.

All brain injuries are different and they all heal differently. Best to both of you.
