I’ve also been to a hospital where someone was experiencing that, but I never asked and also thought it was more a symptom of the disease and not a side effect. I’m on risperdal and have never experienced this side effect.
But risperidon does something to the muscles of the body. I’ve experienced muscle rigidness. I did a google search and found this. Since there is a connection to risperidone messing with the muscles, there might also be a connection with it and laughter… I hope this makes sense. Am I the only one who thinks that it’s a possibility? hehe
“Then there’s Angelman syndrome and Tourette syndrome, both of which carry laughter as a symptom. … They laugh frequently due to heightened stimulation of the parts of the brain that control happiness. Tourette syndrome (TS) is a neurobiological disorder that causes a combination of tics and involuntary vocal outbursts.”
