Sounds like you may be having a form of absence seizure when you lose track of what is going on.

I hope you are seeing a good neuro, not a garden variety one. You need someone who will dig to figure out what is going on.

Have you considered filing a Work Comp claim ? The combined head impacts are likely causing your struggles.

Those doctors who said a concussion must have a 'seeing stars' moment have not be well trained. But, taking time off would not have made much difference long term.

You might ask for a DTI MRI. The neuro may suggest an EEG.
