My son regressed two years ago (at age 6 years). He changed dramatically! Symptoms started with self talk, whispering, running back and forth, severe anxiety (especially separation anxiety), hallucinations, constant biting on absolutely everything all the day, lack of sleep, hypermania with unstoppable laughters, severe depression episodes and rages, misophonia, tics, mutism for one year, avoid eye contact for a couple of months, stopped playing with brother or friends, cognitive decline, deterioration in hand writing (used to be artist but now cannot draw a single line!) and the list is so long.
Now he is communicating better, less anxious, less rages, but he spends most of his days banging toys and other stuff on the floor and the wall while generating sounds (seems like compulsions). He is fully occupied with this and cannot stop it!
He had autism assessment 2 years after this onset, and it was ruled out. Symptoms appeared at age 6 and wasn't there before. It's very painful to not knowing what he has! And how to help him! He still doesn't have any diagnosis. All tests, MRI, WGS..etc came back normal.
Please share your thoughts if you have any 😔🥹
