This document addresses activity therapy (for example, music, dance, art or play therapies) when used to treat Autism Spectrum Disorders (ASDs) and Rett syndrome. ASDs, as defined in the fifth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5), include disorders previously referred to as:

Investigational and Not Medically Necessary:
Activity therapy, including but not limited to music, dance, art or play therapies, is considered investigational and not medically necessary for the treatment of Autism Spectrum Disorders and Rett syndrome.
ASDs and Rett syndrome are complex and multifaceted conditions for which there is no known specific etiology, although there is evidence of a genetic etiology in ASDs. The impairments of these conditions are generally severe, and, given the uncertainty around the cause(s) of these disorders, treatments are not directed at the core pathology, but at the comorbid medical and behavioral conditions.
The use of activity therapy methodologies for the treatment of ASDs and Rett syndrome have not been studied well, and there is a lack of sufficient evidence addressing their effectiveness, safety, relevance, and/or reliability in improving the pathological manifestations of ASDs.
In May 2013 the American Psychiatric Association (APA) released the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This edition of the DSM includes several significant changes over the previous edition, including combining several previously separate diagnoses under the single diagnosis of "autism spectrum disorder." This diagnosis includes the following disorders, previously referred to as: atypical autism, Asperger's disorder, childhood autism, childhood disintegrative disorder, early infantile autism, high-functioning autism, Kanner's autism, and pervasive developmental disorder not otherwise specified. All of these conditions are now considered under one diagnosis, ASD. It should be noted that Rett is not included in the new DSM-5 ASD diagnostic group.
The DSM-5 describes the essential diagnostic features of autism spectrum disorder as both a persistent impairment in reciprocal social communication and restricted and repetitive pattern of behavior, interest or activities. These attributes are present from early childhood and limit or impair everyday functioning. Parents may note symptoms as early as infancy, and the typical age of onset is before 3 years of age. Symptoms may include problems with using and understanding language; difficulty relating to or reciprocating with people, objects, and events; lack of mutual gaze or inability to attend events conjointly; unusual play with toys and other objects; difficulty with changes in routine or familiar surroundings, and repetitive body movements or behavior patterns. Children with childhood disintegrative disorder are an exception to this description, in that they exhibit normal development for approximately 2 years followed by a marked regression in multiple areas of function.
Individuals with ASD vary widely in abilities, intelligence, and behaviors. Some children do not speak at all, others speak in limited phrases or conversations, and some have relatively normal language development. Repetitive play skills, resistance to change in routine and inability to share experiences with others, and limited social and motor skills are generally evident. Unusual responses to sensory information, such as loud noises and lights, are also common. Children unaffected by ASDs can exhibit unusual behaviors occasionally or seem shy around others sometimes without having ASD. What sets children with ASD apart is the consistency of their unusual behaviors. Symptoms of the disorder have to be present in all settings, not just at home or at school, and over considerable periods of time. With ASD, there is a lack of social interaction, impairment in nonverbal behaviors, and a failure to develop normal peer relations. A child with an ASD tends to ignore facial expressions and may not look at others; other children may fail to respect interpersonal boundaries and come too close and stare fixedly at another person. Individuals with ASDs may require additional assessments to differentiate between ASDs and other conditions that may co-occur, such as limited intellect.
The exact causes of autism are unknown, although genetic factors are strongly implicated. A study released by the Center for Disease Control and Prevention (2014) indicates that the incidence of ASD was as high as 1 in 68.
Rett syndrome is a disorder of the nervous system that leads to regression in development, especially in the areas of expressive language and hand use. In most cases, it is caused by a genetic mutation. It occurs almost exclusively in girls and may be misdiagnosed as autism or cerebral palsy.
Seventy-five percent of Rett syndrome cases have been linked to a specific genetic mutation on the X chromosome. This gene contains instructions for creating methyl-CpG-binding protein 2 (MeCP2), which regulates the manufacture of various other proteins. Mutations in the MeCP2 gene cause these other proteins to be produced incorrectly, which damage the maturing brain. Studies link mutations in this gene. Most cases of the mutation arise spontaneously without any traceable cause. However, there also seem to be some clusters within families and certain geographic regions, for example Norway, Sweden, and Northern Italy.
A child affected with Rett syndrome normally follows a standard developmental path for the first 5 months of life. After that time development in communication skills and motor movement in the hands seems to stagnate or regress. After a short period, stereotyped hand movements, gait disturbances, and slowing of the rate of head growth become apparent. Other problems may also be associated with Rett syndrome including seizures, disorganized breathing patterns while awake and apraxia/dyspraxia (the inability to program the body to perform motor movements). Apraxia/dyspraxia is a key symptom of Rett syndrome and it results in significant functional impairment, interfering with body movement, including eye gaze and speech.
The use of various activity therapies have been investigated for the treatment of ASDs and Rett syndrome. To date, the published peer-reviewed scientific studies addressing music, dance, art and other activity therapies is weak and does not provide substantial evidence that such treatment methods provide any significant benefits.
Asperger's syndrome: A developmental disorder that affects the parts of the brain that control social interaction and communications.
Autism Spectrum Disorders: A collection of associated developmental disorders that affect the parts of the brain that control social interaction and verbal and non-verbal communication.
Childhood disintegrative disorder: A developmental disorder characterized by marked regression in multiple areas of functioning following a period of at least 2 years of apparently normal development.
Rett syndrome: A developmental disorder that affects the parts of the brain that control social interaction, communications, and motor function.
