Yes - it is essential that his doctors have all possible information regarding his pre-trauma cognitive abilities. If he doesn't have IQ scores, then SAT scores, especially if he has ones from the 1980's (with MENSA conversion charts) would work better than GRE scores due to low ceiling. My DS' IQ score dropped a couple of SD after the medical equivalent of massive brain trauma but all of the indices were still average except for processing speed, which was only in the average range previously. There is also a pattern to how different types of cognitive abilities recover. The brain is an amazing organ and hopefully your friend will recover most of what he loses with time and therapy.
