Type "traumatic brain injury" in your search engine. There are a ton of websites that can really give you some good info and help! I had a tbi in 1999, so I know alot about it. Feel free to e~mail me, I'd be glad to answer any questions that you may have. I will tell you this, a tbi really effects moods, personality, memory, even anger control. In the beginning, it's very hard and confusing for a tbi patient. Please know that it will get better, it just takes time. Good luck to you and your husband.
