Our son was diagnosed when he was 7, at that time he had both vocal and physical tics like hand clapping, shoulder shrugging and making high pitched squeaking sounds. We have noticed his tics definetly increase during times of stress eg. when his grandma died, we moved, something happened in school etc. We have also noticed that there are sometimes weeks that we don't see or hear any tics. He is very concerned with his appearance and is sensitive to labels, seams and layering of clothing. He does have some social issues when meeting people and makes odd facial expressions, changes his voice and doesn't answer questions directly. My husband and I have just noticed this recently, does anyone have ideas on destressing social contact?
