I heard a case that a diabetic man killed his wife and does not remember a thing and that medically it is possible.
Excuse the digression, but in response to the above, I am diabetic and have not experienced anything remotely resembling the criminal compulsion cited in the example above. Also, in all my reading on the subject of diabetes, I've not seen it either. Of course, that doesn't prove it couldn't happen. Low blood sugar induces a state characterized by hunger, jitters/irritability, and sweating, among other symptoms. If blood glucose is allowed to go too low, a coma and possible death could be the outcome. I've experienced low blood sugar but have always remedied it promptly. I don't think I would be prompted to strangle anyone no matter how low my blood glucose level became. In other words, I believe the proclivity toward committing such a heinous act must have been present.
