We had a teen with a similar disability who attended our church. He would burst out every minute or so in a blood-curdling shriek. It was very distracting, and the anticipation of his next outburst put everyone on edge. Impossible to concentrate.
We had a cry room, but his behavior would send the babies into fits.
We avoided the services he attended, and eventually he stopped going altogether.
Probably Tourettes. Poor guy.
My daughter had one at her school. It was like having a fire alarm with a short in it.
