His tumor was successfully removed, but it took some of his mental functions (and most of his motor skills) with it. Much of his face is paralyzed, locked into a permanent sneer. He has difficulty going down stairs, giving hugs, pouring milk, and even placing objects into cabinets. His view of the world is distorted, he finds it difficult to speak and comprehend others speaking, and his life is forever dulled. He still retains enough brain function to know who he once was, and just how much he has lost.
