"Cured" Charlie
After the operatiion, Charlie may be smarter but he does not fit the definition of neurotypical either. Instead, he is a savant with almost all of the common Asperger's stereotypes. He trades in his Intellectual Disability for a Social Disability. Charlie has many new skills that show his intelligence (he speaks more than one language, has a photographic memory, and possess high level skills in neuroscience and math). However, Charlie becomes socially awkward because he is now too smart. For example, when he goes to a party at the university he tries to start conversations with some "experts" in their field of study. Instead of realizing they are leaving the conversation because he is boring them, he thinks they are trying to hide their lack of knowledge in the subject.
He is also very rigid, and his life is rule bound. He is obsessed with his work, and the relationships he had with people start to break. Professor Nemur, seeing Charlie's new personality tells him he went from a kind Intellectually Disabled man to a miserable, unlikable one. However, this condition presented as better than the way he started the novel. Charlie and those around him act as if he were dying as he starts to lose his intelligence. Charlie even says that visiting the Warren Home where he will go was like sitting in his coffin. Even though his life is now miserable, it is seen as preferable to him having an Intellectual Disability.
