Math / cognitive skills is the dimension that has improved the least unfortunately. The brain fog has almost disappeared, which is great, and for short periods of time I feel completely fine. But my problem is that my brain has become intolerant to the prolonged effort required to do math at a professional level. Ideally I should be able to concentrate on a problem for 3 hours uninterrupted, read papers, write equations, etc., but this type of effort gives me strong headaches quite quickly, and even a full-blown relapse if I don't stop. This is frustrating, and this forces me to consider a career change, but at the moment I am mostly feeling happy and grateful about the improvement in my physical symptoms.

About your tinnitus, you are probably aware of this already, but professional ear plugs make a huge difference, as they protect your ears while preserving the quality of the sound. I used to be an amateur musician too and I used these regularly (before PCS forced me to give up on music).

Vania, in my experience the brain fog is the last symptom to clear up - it took me 3 years before it was completely gone. So dont give up on your career plans yet:-)

While that does sound frustrating, I want to side with norwegian and say keep your chin up - it seems like your ability to think properly has just about restored, it's only the fatigue that is getting to you. Maybe with some more time and exercising properly, you'll have the energy to work for longer! While nothing is certain in this whole realm, it does seem encouraging that you have periods where you can think clearly.

Just curious, have you used any specific modalities (LLLT, chiro, etc...) over the course of your recovery? or has it been more 'organic'

This is a great post! I also am having issues with post concussive syndrome, but mostly with anxiety with re-injury. I especially appreciate he fact about setting yourself up for a timeline is a setup for failure. In my mind I figured I would be back to normal in 6 weeks because that is what I had been used to with past concussions. Now I am almost 1.5 years in and still working on it. I have seen psych and neuro optometry. I think there is something to the vision piece, but wish I could find a good doc for the anxiety component. I’m sure I have poor coping mechanism with no prior psych history though. Glad to see you are recovering though!

The chiro helped with my tesion headaches, but that's it.

I've been meaning to give 'brainHQ' a shot. If you haven't heard, it's a computer app for cognitive skills, and supposedly it avoids the pitfalls of 'lumosity' and similar apps in that the training carries much better to overall brain aptitude. I'm not 100% sold on it, but its low cost and they did one study on veterans showing that it fared better than other games, so I want to give it a go

I had a look at it and that sounds interesting. Would you mind sharing your experience once you know more about it? Thanks a lot! And all the best to you.
