Final answer:
Tourette's Disorder involves one or more motor or verbal tics (but not both) for at least one year.
Step-by-step explanation:
Tourette's Disorder is a neurological condition characterized by repetitive, involuntary movements or vocalizations known as tics. These tics can be motor (involving physical movements) or vocal (involving sounds or words). To meet the criteria for Tourette's Disorder, there must be the presence of one or more motor or vocal tics (but not both simultaneously) for at least one year.
Tourette's Disorder often begins in childhood or adolescence, and the severity and nature of tics can vary widely among individuals. While tics are the defining feature of Tourette's, individuals with the disorder may also experience associated conditions such as attention-deficit/hyperactivity disorder (ADHD) or obsessive-compulsive disorder (OCD).
