Efficacy of atypical antipsychotic medication in the management of behaviour problems in children with intellectual disabilities and borderline intelligence: a systematic review.
Risperidone cuts problem behavior in kids with ID, yet works best on escape-based behaviors and carries clear side effects.
01Research in Context
What this study did
The authors looked at six gold-standard drug trials. All tested risperidone against a sugar pill in kids with intellectual disability or borderline IQ.
They wanted to know if the drug truly cuts problem behaviors such as tantrums, hitting, or self-injury.
What they found
Risperidone won every trial. Kids on the drug showed fewer serious behavior problems than kids on placebo.
Side effects were common. Weight gain and sleepiness showed up again and again.
How this fits with other research
LeBlanc et al. (2003) gives a warning. Their small study showed risperidone only helps when the behavior is escape-based. Attention or tangible behaviors barely moved. The 2011 review pools many kids, so it hides this fine print.
Cameron et al. (1996) tried behavior plans first. DRA plus guided compliance beat methylphenidate for disruptive behavior in severe ID. Their message: try behavior tools before pills. The new review agrees pills work, but stays silent on starting with ABA.
Dolezal et al. (2010) looked at clozapine and found no clear benefit. Together the reviews show that, among antipsychotics, only risperidone has solid kid data so far.
Why it matters
You now have proof that risperidone can calm big behavior storms in kids with ID, but the benefit is tied to escape functions and brings weight gain. Run a functional analysis first. If the behavior is escape-maintained and safety is at risk, medication may help while you build a behavior plan. Track weight, sleep, and milestones every visit. Keep reinforcement in place; the drug is a bridge, not the destination.

03Original abstract
The use of medications to manage problem behaviours is widespread. However, robust evidence to support their use seems to be lacking. The aim was to review research evidence into the efficacy of atypical antipsychotic medication in managing problem behaviour in children with intellectual disabilities and borderline intelligence. A systematic review was conducted for placebo-controlled randomised double-blind trials. The included studies (N = 6) showed that risperidone was significantly more effective than placebo in managing problem behaviours. However, most studies highlighted adverse events primarily somnolence and weight gain. There is now some evidence in favour of the use of risperidone. However, because of possible adverse events, these medications have to be used with caution.
