A good place to go for Traumatic Brain Injury and PCS explanations in laymans terms is:
www.tbiguide.com
It has a simple table of contents that breaks down causes, symptoms, family support, etc. It gave my family a much better insight into what I'm dealing with.
As a 56 yr old man, I have issues with accepting that I currently can't do things that I could do before. Maybe it's a male ego thing, don't know and it really doesn't matter. The bottom line is that your brain takes time to heal and that timeline is variable to everyone differently.
I have full expectations of a complete recovery, being patient is the hard part.
Good luck to you and your husband.
