Red flags

  • New or sudden change in behaviour — treat as medical until proven otherwise (pain, constipation, dental disease, infection, epilepsy, delirium, medication toxicity or akathisia)
  • Severe self-injury or aggression causing tissue damage, fracture risk, or placement crisis — safety plan and functional analysis urgently; do not start open-ended antipsychotics without formulation
  • Long-term antipsychotic for 'behaviour' with no recorded mental illness — deprescribe carefully with multiagency support (STOMP principles)
  • Diagnostic overshadowing: depression, psychosis, trauma or abuse attributed solely to intellectual disability
  • High-dose polypharmacy or chemical restraint without capacity discussion, monitoring, or review date
  • Restrictive practices used without least-restrictive alternatives, documentation, or behaviour support plan

The one-line answer

Challenging behaviour in intellectual disability is a description of risk and impact, not a psychiatric diagnosis. Complete a functional analysis (attention, escape, tangible, automatic); exclude pain and treatable mental illness; deliver positive behaviour support (PBS) first; and reserve antipsychotics for severe residual risk after non-drug optimisation, with a time-limited plan — Tyrer 2008 showed risperidone and haloperidol were not superior to placebo for aggressive challenging behaviour in adults with ID.[1][3][6][11]

Meet the patient

A 34-year-old man with severe intellectual disability and no speech has been head-banging for two weeks. The group home staff are exhausted; one has a bruised forearm from trying to restrain him. They fax a referral asking you to "increase the risperidone."[2][11]

He is already on risperidone 3 mg daily, prescribed three years ago "for behaviour," with no recorded mental illness and no review date. Two questions decide whether he gets better or gets another milligram. What is the behaviour achieving for him? And what changed two weeks ago?[1][6]
