Which disorder is characterized by repetitive motor movements known as tics?

Tourette's syndrome is indeed characterized by the presence of tics, which are repetitive, involuntary movements or vocalizations. Individuals with this condition may exhibit physical tics such as blinking, head jerking, or shoulder shrugging, as well as vocal tics like throat clearing, grunting, or even the utterance of inappropriate words. The definition of tics aligns perfectly with the characteristics of Tourette's syndrome, making it the correct answer in this context.

In contrast, the other disorders listed—Generalized Anxiety Disorder, Obsessive-Compulsive Disorder, and Panic Disorder—do not primarily feature tics. Generalized Anxiety Disorder is characterized by excessive worry and anxiety about various aspects of life, while Obsessive-Compulsive Disorder involves unwanted intrusive thoughts (obsessions) and repetitive behaviors (compulsions) that the person feels driven to perform. Panic Disorder is primarily associated with sudden and intense episodes of fear or panic attacks. None of these conditions involve the repetitive motor movements that define Tourette's syndrome.
