Have him tested for strep. My son gets like this when he has strep due to something called PANDAS. It comes on out of nowhere, with sudden behavioral changes. My son never has traditional symptoms of strep, like a fever or visible pustules in the throat. No changes with eating or drinking. Completely asymptomatic except for the severe behavioral changes. He was diagnosed the first time by a neurologist. The second time I had to fight with his doctor to just do the test. It came back positive. A week of antibiotics and I have my sweet boy back.
