Persistent vocal tic disorder is a condition characterized by the presence of vocal tics that last for more than a year. These tics can include sounds such as throat clearing, grunting, or other involuntary noises. Unlike Tourette syndrome, which involves both motor and vocal tics, persistent vocal tic disorder focuses solely on vocalizations. The exact cause of persistent vocal tic disorder is not fully understood, but it may involve genetic and environmental factors. Treatment options often include behavioral therapies and, in some cases, medication to help manage symptoms. Early intervention can improve outcomes for those affected.
