Motor Disorders

Question 1

what is the diagnostic criteria for Developmental Coordination Disorder?

Answer 1

Criterion A: The acquisition and execution of coordinated motor skills is substantially below that expected given the individual’s chronological age and opportunity for skill learning and use (CLUMSY)

Criterion B: The motor skills deficit in Criterion A significantly and persistently interferes with activities of daily living appropriate to chronological age

Criterion C: Onset of symptoms is in the early developmental period.

Criterion D: The motor skills deficits are not better explained by other disorders

Question 2

what are the disorders categorized as motor disorders?

Answer 2

1. Developmental Coordination Disorder
2. Stereotypic Movement Disorder
3. Tic Disorders

Question 3

what is the diagnostic criteria for stereotypic movement disorder?

Answer 3

Criterion A: Repetitive, seemingly driven, and apparently purposeless motor behavior (e.g., hand
shaking or waving, body rocking)

Criterion B: The repetitive motor behavior interferes with social, academic, or other activities and
may result in self-injury

Criterion C: Onset is in the early developmental period.

Criterion D: The repetitive motor behavior is not attributable to the physiological effects of a substance or neurological condition and is not better explained by other disorders

Question 4

what are the specifiers of Stereotypic Movement Disorder?

Answer 4

1. with self-injurious behavior
2. without self-injurious behavior

Question 5

what is the diagnostic criteria for tourette’s disorder?

Answer 5

Criterion A: Both multiple motor and one or more vocal tics have been present at some time during
the illness, although not necessarily concurrently.

Criterion B: The tics may wax and wane in frequency but have persisted for more than 1 year since the first tic onset

Criterion C: Onset is before age 18 years.

Criterion D: The disturbance is not attributable to the physiological effects of a substance

Question 6

what is the diagnostic criteria for Persistent (Chronic) Motor or Vocal Tic Disorder?

Answer 6

Criterion A: Single or multiple motor or vocal tics have been present during the illness, but not both motor and vocal.

Criterion B: The tics may wax and wane in frequency but have persisted for more than 1 year since the first tic onset.

Criterion C: Onset is before age 18 years.

Criterion D: The disturbance is not attributable to the physiological effects of a substance

Criterion E: Criteria have never been met for Tourette’s disorder.

Question 7

what are the specifiers for tic disorders? (only required for persistent (chronic) motor or vocal tic disorder

Answer 7

1. with motor tics only
2. with vocal tics only

Question 8

what is the diagnostic criteria for Provisional Tic Disorder

Answer 8

same for other tic disorders but criteria have never been met

Question 9

what is a tic?

Answer 9

a tic is a sudden, rapid, recurrent, nonrhythmic motor movement or vocalization.
