text: <unk>  is a disorder of childhood involving repetitive, nonfunctional motor behavior (e.g., hand waving or head banging), that markedly interferes with normal activities or results in bodily injury, and persists for four weeks or longer.  The behavior must not be due to the direct effects of a substance or another medical condition.  In cases when mental retardation is present, the<unk>  or self-injurious behavior must be of sufficient severity to become the focus of treatment.  The behavior is not better explained as a compulsion (e.g.; OCD), a tic, a stereotypy as part of a pervasive developmental disorder, or hair pulling (trichotillomania).  Former versions of the DSM (Diagnostic Manual and Statistical Manual of Mental Disorders) used the term Stereotypy/Habit Disorder to designate repetitive habit behaviors that caused impairment to the child.  When stereotyped behaviors cause significant impairment in functioning, an evaluation for<unk>  is warranted.  There are no specific tests for diagnosing this disorder, although some tests may be ordered to rule out other conditions.
