A young client has been brought to a clinic for evaluation. The client has developed several motor tics and shouts throughout the day. The mother states this has been going on for over a year. Which disorder does the nurse suspect this to be?

Tourette disorder is a neurodevelopmental syndrome characterized by multiple motor tics and at least one vocal tic persisting for over 1 year. The pathophysiology involves basal ganglia dysfunction and abnormalities in neurotransmitter pathways, particularly involving dopamine signaling. Onset typically occurs in childhood, and symptoms frequently wax and wane in severity while significantly impacting social and academic functioning. Rationale: A. Autism spectrum disorder is primarily characterized by deficits in social communication and restricted, repetitive patterns of behavior. Although repetitive movements may occur, they are not the rapid, involuntary arrhythmic contractions seen in tic disorders. Diagnosis requires significant impairment in social interaction and communication which is not the primary feature described. B. Attention deficit hyperactivity disorder involves a persistent pattern of inattention and impulsivity. Although ADHD frequently co-occurs with tic disorders, the presence of specific motor and vocal tics for over a year is pathognomonic for Tourette rather than a standard presentation of hyperactivity or executive dysfunction symptoms. C. The combination of multiple motor tics and vocal tics like shouting for a duration exceeding 12 months meets the diagnostic criteria. Tourette disorder is distinguished by this specific chronicity and variety of tics. The nurse recognizes that vocal tics can range from simple sounds to complex vocalizations or shouted words. D. Communication disorders focus on difficulties with language acquisition, speech fluency, or social use of verbal and nonverbal communication. Shouting as a tic is an involuntary physical vocalization rather than a deficit in linguistic structure. Therefore, the symptoms provided point toward a neurological tic disorder rather than a speech-related impairment.
