In which motor disorder do individuals exhibit involuntary movements under stress but can suppress them at times?

• A. Developmental Coordination Disorder
• B. Tic Disorders
• C. Stereotypic Movement Disorder
• D. Provisional Tic Disorder

Answer: (B)

Tic Disorders involve the presence of involuntary movements or vocalizations that can vary in intensity and frequency. Individuals with tic disorders often exhibit these involuntary movements, known as tics, especially in response to stress or excitement. Interestingly, many individuals with tic disorders have the ability to temporarily suppress their tics, especially in certain social situations or when they are focused on an activity. However, this suppression typically leads to a rebound increase in tics once the individual is no longer consciously trying to control them. This characteristic of being able to suppress tics, particularly under stress, sets Tic Disorders apart from other motor disorders. In contrast, Developmental Coordination Disorder primarily impacts motor skill acquisition and coordination rather than involuntary movements. Stereotypic Movement Disorder involves repetitive, purposeless movements that occur consistently, typically without the same capacity for suppression that is characteristic of tic disorders. Provisional Tic Disorder features tics that are present for less than a year and can also be alleviated during certain conditions, but it still falls under the broader category of tic disorders. Hence, the portrayal of individuals with involuntary movements that can be temporarily controlled aligns most closely with the traits of Tic Disorders.
