What are the medical treatment options for behavioral issues in a 12-year-old child with Autism Spectrum Disorder (ASD)?

From the Guidelines

Medical treatment for behavioral issues in a 12-year-old with Autism Spectrum Disorder (ASD) should prioritize a combination of medication and behavioral therapy, with a focus on targeting specific symptoms such as irritability, aggression, and anxiety. According to the most recent and highest quality study 1, pharmacotherapy may be offered to children with ASD when there is a specific target symptom or comorbid condition. The study suggests that medications such as risperidone can help manage irritability and aggression, while SSRIs like fluoxetine or sertraline may be beneficial for anxiety and repetitive behaviors.

Some key considerations for medical treatment include:

• Starting medication at low doses and gradually increasing while monitoring for side effects
• Combining medication with behavioral therapy approaches, such as parent training and applied behavior analysis
• Regular follow-ups with a child psychiatrist to adjust treatment based on response
• Keeping a daily log of behaviors, medication effects, and side effects to guide treatment decisions

It's also important to note that behavioral interventions, particularly early intensive behavioral and developmental interventions, can be highly effective in managing behavioral issues in children with ASD 1. These interventions can be delivered in a home or school setting and are generally time-intensive, with some programs requiring up to 40 hours a week.

In terms of specific medications, the following may be considered:

• Stimulants like methylphenidate (Ritalin, Concerta) at 18-54 mg daily or amphetamine salts (Adderall) at 5-30 mg daily, particularly if ADHD symptoms are present
• Antipsychotics such as risperidone (0.5-3 mg daily) or aripiprazole (2-15 mg daily) to manage irritability and aggression
• Alpha-2 agonists such as guanfacine (1-4 mg daily) or clonidine (0.1-0.4 mg daily) to help with impulsivity and hyperactivity

Overall, a comprehensive treatment plan that incorporates both medication and behavioral therapy can help improve symptoms and quality of life for children with ASD and behavioral issues.

From the FDA Drug Label

The efficacy of RISPERIDONE in the treatment of irritability associated with autistic disorder was established in two 8-week, placebo-controlled trials in children and adolescents (aged 5 to 16 years) who met the DSM-IV criteria for autistic disorder. Over 90% of these subjects were under 12 years of age and most weighed over 20 kg (16-104. 3 kg). Efficacy was evaluated using two assessment scales: the Aberrant Behavior Checklist (ABC) and the Clinical Global Impression - Change (CGI-C) scale. The primary outcome measure in both trials was the change from baseline to endpoint in the Irritability subscale of the ABC (ABC-I) RISPERIDONE, starting at 0.25 mg/day or 0. 5 mg/day depending on baseline weight (< 20 kg and ≥ 20 kg, respectively) and titrated to clinical response (mean modal dose of 1.9 mg/day, equivalent to 0.06 mg/kg/day), significantly improved scores on the ABC-I subscale and on the CGI-C scale compared with placebo.

Treatment of behavior issues in a child with ASD:

• Risperidone can be used to treat irritability associated with autistic disorder, including symptoms of aggression towards others, deliberate self-injuriousness, temper tantrums, and quickly changing moods.
• The recommended dose is 0.5-3.5 mg/day on a weight-adjusted basis, starting at 0.25 mg/day or 0.5 mg/day depending on baseline weight (< 20 kg and ≥ 20 kg, respectively) and titrated to clinical response.
• The mean modal dose of 1.9 mg/day, equivalent to 0.06 mg/kg/day, has been shown to significantly improve scores on the ABC-I subscale and on the CGI-C scale compared with placebo 2.
• For a 12-year-old child, the dose may need to be adjusted based on weight and clinical response.
• It is essential to closely monitor the child's response to the medication and adjust the dose as needed to minimize side effects and maximize efficacy.

From the Research

Medical Treatment for Behaviour Issues in Children with ASD

To address behaviour issues in a 12-year-old child with Autism Spectrum Disorder (ASD), medical treatment options can be considered in conjunction with therapeutic approaches.

• Applied Behavior Analysis (ABA): ABA has been shown to be effective in helping individuals with autism achieve their goals 3, 4.
• Occupational Therapy: While occupational therapy literature does not reflect the use of ABA, the two approaches can be compatible and work synergistically 3.
• Behavioral Analysis Programs: Research has demonstrated that behavioral analysis programs can significantly improve social, communicative, and daily life skills in children with ASD 4.

Implementation of ABA

ABA principles can be applied to expand occupational therapy practice, and its strong evidence base suggests it could be a valuable addition to treatment plans for children with ASD 3.

• Individualized Sessions: Implementing ABA programs individually, such as in eight one-hour sessions twice a week, has been shown to be effective in improving social and communicative skills 4.
• Structured Sessions: Delivering ABA interventions through structured sessions can enhance emotional and social development in children with ASD 4.
