Hi and welcome to NT.

PTSD is very common among those of us who sustain our brain injuries in car accidents.

I believe that your doctor is overstating, grossly, the connection between your PCS and PTSD. I doubt that eliminating your PTSD will make your PCS disappear. However, as Mark said, any decrease in your anxiety level will be an asset to your healing and make you feel better, overall. You should definitely seek treatment for your PTSD.

The good news is that the vast majority of people with MVA induced PTSD can be helped. How bad are your symptoms? Do you have flashbacks or just general anxiety about being in a car? Assuming you weren't looking in your rear view mirror, you didn't see it coming. Not having a chance to become terrified can be a big bonus in terms of a positive treatment outcome.

My accident was horrendous and, like yours, was caused by a negligent driver and a cell phone. In the immediate aftermath, just the thought of being a passenger in a car made me break out in a cold sweat. Now, while the car will never be my "happy place," I can ferry my child to her activities, like a normal mom. The only time I get anxious is when I see another driver do something really reckless - but I figure that's a pretty normal response for any thinking person.

I was lucky because I found a therapist willing to work on the triggers for my PTSD, not just medicate away the symptoms.

With the proper help, you can overcome your PTSD.
