Mental Defect?

I get the feeling that the narrator (and, to an extent, Dostoevsky) may have some sort of medical/mental condition. He displays the signs of someone with Asperger's Syndrome (speaking from my observations of an acquaintance). He doesn't have a grasp on whether or not someone is interested in his conversation, and he doesn't see the signs that they don't want to be with him when the men move to the couch. He's having trouble connecting with the person he's speaking to, and he seems to ramble on and on without an end. Because a book displays some auto-biographical qualities, I think that Dostoevsky may have had Asperger's Syndrome himself. I looked into his life, and Dostoevsky did have his share of medical problems with seizures and epilepsy. It's possible that he had other illnesses that were never diagnosed. Nonetheless, I think that Dostoevsky will continue to ramble on and have instances of awkwardness in which he never really perceives that he's not wanted.
