One of my high school seniors goes into laughing fits that he cannot stop. I've been his teacher for 4 years and know him very well. This is not drugs or goofing off. If he finds something funny (internal or external stimuli) he often cannot stop laughing to the point of tears. I'm concerned about how this behavior will be perceived in college and the workplace. He is high functioning on the Autism spectrum, by the way. He is getting his diploma and functions on the level of a moderate learning disability. He and I have discussed this. He knows he has trouble controlling the laughter. I am looking for suggestions.
