Tic disorders are characterized by which features?

• A. Recurrent, non-rhythmic movements and involuntary sounds
• B. Chronic fatigue and malaise
• C. Hallucinations
• D. Delusions

Answer: (A)

Tic disorders are marked by sudden, rapid, recurrent, nonrhythmic motor movements or vocalizations. These tics are typically involuntary (though they can be temporarily suppressed with effort) and can vary in frequency and intensity over time. They often begin in childhood and may wax and wane, with examples including eye blinking, facial grimacing, throat clearing, and squeaking. This description matches tic disorders, whereas fatigue and malaise, hallucinations, or delusions describe other kinds of conditions and are not characteristic of tic disorders.
