I don't see a reason for a neurosurgeon. A neurologist would be more appropriate. A neuropsychologist would also be worthwhile.

I agree that the Diet Dr Pepper needs to be moderated. Artificial sweeteners can be very problematic. The caffeine content can be a problem, too.

I have had periods of post trauma seizures. My doctor says they are not epilepsy. I would have moments where my recall was nil and other thought processes were a struggle. But, I was also having absence seizures (petit-mal was the term at the time).

There is symptom overlap with many conditions so thinking about epilepsy based on an overlap of symptoms is not wise.

Stress can cause a PCS compromised brain to have recall struggles. Startle can cause it too. Too much stimulation can cause it.

The only thing we do about it is realize there is a trigger and try to avoid the trigger or know our recall will be poor during those times.
