Our child was diagnosed with ADHD, TS, and Seizure
Disorder. Our child does have facial twitching, shoulder shrugs, and various other things, as well as ADD symptoms like daydreaming in class, not completing assignments, being forgetful, etc. I could list them all but I'm sure that's really necessary.
They did an EEG and blood work and urine tests to rule out other things such as lead and copper and such.
