At twelve years old, the child you describe may have a mental challenge. Did it come on suddenly or has it been building up? Did the school let you know something was amiss? If it's a sudden onset he may have been exposed to some type of toxic as a trigger and hopefully it was drugs from a classmate. He needs to be seen by an MD who can do toxicology and other tests. If they prove negative, then a child psychologist is the next stop. He needs help and right away.
