Persistent Tics in Adulthood
A 33-year-old man with childhood-onset motor and vocal tics that improved and nearly resolved in his twenties but returned in his thirties. As demonstrated, complex motor tics involve cervical, pharyngeal, and laryngeal muscle groups. The urge to perform tic movements was suppressible during requested performance of complex motor tasks. Although suppressibility is a functional or psychogenic feature, this patient has Tourette syndrome, with recrudescence of tics into adulthood.
