In all ways except his memory, he was a healthy man of sound mind. I'm no expert on medical ethics, but I would argue that he was capable of informed consent. Remember that his working memory and other cognitive abilities were unaffected, which is part of the reason his case was so interesting. Obviously, he would not be able to consent to the long-term study they performed on him. For a particular study, however, if you explained the situation to him he would be able to understand it.
