I think doctor will tell you you cannot compare.

The course may be able to teach him to link new information to his working memory threads if it is physicaly possible. It would be a slow process that requires persistence. The course would encourage him to record his history as it comes to him and create a timeline. It will be an aide for remembering again and again.

The thing is it could help but you cannot know until you tried. If you do get the course you can ask for an extension of the guarantee for up to six months If you decide it didn't help or is too much work you can return it for a refund.
