My spouse was attacked by men with baseball bats on August 16th of this year, they split his scalp wide open he had 40 staples, and 200 plus stitches. has had a headache since, underwent an ekg, and now is scheduled for an MRI. I am very concerned because since he was attacked he keeps passing out sometimes more than once a day, and has constantly been complaining of a headache, and feeling extremely tired. He cannot concentrate whatsoever, and when he saw a neurologist the neurologist asked him if he could remember some words and he could not a few minutes later. My husband already has a TBI from being in Iraq, and now this. What warning or emergency signs should I watch for. Is this all normal after a head injury? He was in bed for 5 days after the attack sleeping mostly.
