Efforts toward early identification and treatment are an important facet of the public health work in autism spectrum disorder (ASD).

The prevalence of ASD is rising. With the most recent estimate from the Centers from Disease Control and Prevention of 1 in 59* children aged 8 years,1 it is important for pediatric health care providers to have an understanding of current recommendations for treatment so they can counsel and guide affected families. ASD is a heterogeneous condition, so this article seeks to touch on broad principles, recognizing that clinicians must take into account the full clinical picture of each individual and family.

It is important to acknowledge that while there is no cure for ASD, there are treatment modalities that have an evidence base for addressing specific areas that may be impaired in children with autism. While it is beyond the scope of this article to review all of the potential areas of intervention in children with ASD, it is important to be keep in mind a few important principles.

1. The best evidenced treatment for addressing challenging and problematic behavior as well as improving a host of outcomes in children with ASD is itself behavioral in nature. These treatments are based on the principles of applied behavioral analysis,2 an educational and therapeutic approach which involves looking at antecedents and consequences of behaviors. This approach also looks to shape, motivate, and reinforce functional behaviors while discouraging harmful and disruptive ones.

2. Because communication often is impaired in children with ASD, providers always should investigate for possible medical causes of pain or discomfort that might explain sudden behavior change, as well as environmental changes that could be involved.

3. The overarching principle of psychopharmacology in ASD is to start low, and go slow – because children with ASD often are particularly sensitive to medication side effects.
 

Irritability/aggression/extreme mood lability

There are only two medications with Food and Drug Administration labeling for an autism specific condition, and those are aripiprazole and risperidone, two second-generation antipsychotic agents approved for irritability associated with ASD on the basis of randomized controlled trials (RCTs) demonstrating their efficacy.3,4 Included under the umbrella of irritability are aggression, deliberate self-injurious behavior, extreme temper tantrums, and quick and extreme mood changes. For aripiprazole the approved ages are 6-17 years; a dosing range of 2-15 mg/day is recommended. For risperidone, the approved age range is 5-17 years; the recommended dosing range is 0.25-4 mg/day. Prior to starting either of these medications, a cardiac history should be obtained, and baseline laboratory values, particularly lipid levels and hemoglobin A1c (HbA1c) are recommended. All second-generation antipsychotics carry the risk of tardive dyskinesia (a movement disorder), as well as risk of weight gain and metabolic effects. Baseline weight prior to medication initiation with routine follow-up measurement is encouraged. In light of the burden of potential side effects, these medications tend to be reserved by clinicians for circumstances where there is a significant impact on functioning. Both medications are available in liquid form for children with difficulty swallowing pills.

 

 

ADHD

There are positive RCTs of methylphenidate in co-occurring ASD and ADHD,5 making it the preferred first line agent for treatment. Amphetamine salt based stimulant preparations do not have any RCTs in co-occurring ASD, but theoretically should be similarly effective. Again, the principle of starting low and going slow is applicable. Second line are the alpha 2 adrenergic agonists guanfacine and clonidine, both of whose long-acting formulations are approved for treatment of ADHD in children and adolescents without ASD, as well as atomoxetine, a selective norepinephrine reuptake inhibitor approved for ADHD. Guanfacine and atomoxetine have the stronger evidence base in the co-occurring condition. None of the second-line medications come in liquid preparation, although the immediate-release forms of guanfacine and clonidine both can be crushed and are used in clinical practice when the extended-release forms are not practicable.

Anxiety disorders and depression

Repetitive behaviors and insistence on sameness are broad headings that can be thought of as similar to obsessive compulsive disorder in children without ASD. However, controlled studies of SSRIs and clomipramine (a tricyclic antidepressant) have not shown a clear benefit in these behaviors in children with autism. There are no RCTs looking specifically at treatment of anxiety disorders in children with ASD, but expert consensus is that pharmacologic treatment is similar to that of children without ASD, with the SSRIs fluoxetine and sertraline the first-line agents due to the robust evidence for these two medications in treatment of anxiety disorders in children.6 Especially for kids with higher functioning ASD, cognitive behavioral therapy (CBT) should be considered and has some evidence for the co-occurring condition. Similarly, there are no RCTs for co-occurring depression in ASD, and clinical practice is to treat it as you would depression in the non-ASD population. Be aware that the studies of SSRIs in children with ASD reported higher than typical rates of behavioral activation on these medications, and again the principle of starting low and going slow is emphasized. Fluoxetine and sertraline both come in liquid form.

Insomnia

Insomnia is a common occurrence in children with ASD, and studies suggest melatonin can be effective, with immediate release clonidine a consideration with some limited evidence, if melatonin is not successful.

Finally I would be remiss in not mentioning that there is preliminary evidence from review7 and meta-analysis8 articles to suggest that regular exercise for individuals with ASD has a positive effect on multiple symptom domains, suggesting that this is an important additional treatment recommendation for children and families.

In conclusion, identification and treatment of ASD and co-occurring syndromes is often challenging, and while specialty referral often will be necessary, it is hoped that this overview provides a helpful frame of reference for primary care providers who encounter these conditions in clinical practice.

For further reading on this important subject, I recommend the American Academy of Child and Adolescent Psychiatry Practice Parameter for the Assessment and Treatment of Children and Adolescents with ASD and the Parents Medication Guide for Autism Spectrum Disorders.
