What does tourette syndrome look like?

Tourette syndrome is characterized by repetitive, involuntary movements and vocalizations known as tics. Tics can be motor, such as blinking, head jerking, or shoulder shrugging, and vocal, including throat clearing, grunting, or repetitive phrases. The severity and frequency of tics can vary widely among individuals and may be influenced by stress, excitement, or fatigue. While tics often begin in childhood, they can improve with age for some individuals.
