Advice: 21 year old ADHD son goes catonic; Rigid body /smirking face.
Has anyone else seen this? What does it mean when son goes completely catatonic? He stands rigid. You could actually knock him over. No eye contact. Smirk on face, with expression held like that. This could go on for an hour. Nothing reaches him--not touching him, speaking to him. No clear sense of what triggers it. First occurred maybe 2 years ago in the midst of ADHD battles and pleas over deadlines, etc.
