To
Be Identified
Differential
Diagnosis:
Some disorders
have similar or even the same symptoms. The clinician, therefore,
in his/her diagnostic attempt has to differentiate against the
following disorders which need to be ruled out to establish
a precise diagnosis.
Cerebral
Palsy
Delayed-onset Movement Disorder.
Mild Neuromotor Disabilities.
Learning Disabilities.
Autism.
Drug-induced Movement Disorder.
Rett's Syndrome.
Cause:
The causes
of this disorder are unknown. The movements appear to increase
with stress , frustration and boredom. Stereotypic movement
disorder is more common among boys.
Treatment:
Treatment
should be centered around the symptom, cause, and child's age.
The environment should be changed for those children that are
self-injurious to make sure they are safe.
Counseling
and Psychotherapy [ See
Therapy Section ]:
Behavioral
techniques and psychotherapy have been the most successful treatment
modalities.
