I stopped seeing the girl I had been dating for about a month after my TBI in April. In my case however the biggest symptom is just complete emotional detachment where I can't make genuine eye contact at all. This sounds worse for dating than some of the other PCS symptoms.

I would say go for it! There's definitely enough awesome people in the world where you could luck out with someone patient enough to understand your symptoms and still see you for you.

Best of luck
