Which disorder is characterized by involuntary movements and vocalizations?

Tourette Syndrome is characterized by involuntary movements, known as motor tics, and vocalizations, referred to as vocal tics. These tics can range from simple movements, such as blinking or head jerking, to more complex behaviors such as jumping or twirling. Similarly, vocal tics can include sounds like grunting, throat clearing, or even the involuntary utterance of words or phrases. The hallmark of Tourette Syndrome is the presence of both motor and vocal tics, which can vary in severity and frequency over time.

In the context of the other disorders: Parkinson's Disease primarily involves tremors, stiffness, and bradykinesia (slowness of movement) rather than tics. Alzheimer's Disease is primarily associated with cognitive decline and memory loss, not involuntary movements. Epilepsy involves seizures that may include convulsions, but these are not described as tics and do not typically include vocalizations in the same context as Tourette Syndrome. Therefore, the involvement of both motor and vocal tics distinctly identifies Tourette Syndrome as the correct answer.
