Despite the widespread use of psychotropic medications in people with autism spectrum disorder (ASD), there is limited evidence to suggest that psychotropic medications including mood stabilisers are effective in individuals with ASD.

Various parent training interventions have been shown to have some effect on the symptoms of children with autism. We carried out a systematic review and meta-analyses to assess effectiveness of parental training for children with autism on their symptoms and parental stress.

Previous systematic reviews showed no significant association between epilepsy and challenging behaviours in adults with intellectual disabilities.

Although widely used, the current evidence for the efficacy of antidepressant and anti-anxiety medications for people with autism spectrum disorder (ASD) is limited and conflicting.

Psychiatric disorders, such as depression and anxiety, are commonly associated with epilepsy in the general population, but the relationship between psychiatric disorders and epilepsy among adults with intellectual disabilities is unclear.

Challenging behaviour displayed by people with intellectual disabilities (ID) can be difficult to manage if caregivers do not understand the reasons for the behaviour. Identifying the contextual variables/triggers for the behaviour is likely to help undertake a functional analysis leading to a person-centred positive behaviour support plan. Currently, a limited number of checklists are available for trigger assessment and none were developed using an interview with the family caregivers. This article describes the development and contents of the comprehensive assessment of triggers for behaviours of concern scale (CATS). CATS was developed in two stages. Stage 1 used a 'bottom-up' approach, in which caregivers of adults with ID who show aggressive behaviour were interviewed to identify the triggers for aggression. In stage two, using a 'top-down' approach, a comprehensive literature review was conducted to gather items from existing trigger checklists. Trigger items from both stages were combined and the duplicates were removed. The final list in CATS consists of 333 contextual triggers categorised under five main domains and 12 subdomains. CATS can be used by caregivers to identify triggers or antecedents of challenging behaviour. Further work is needed to test its psychometric properties, utility, and acceptability.

Psychotropic medications that are primarily licenced for the treatment of psychiatric disorders are used widely (32%-85%) among people with intellectual disabilities (ID) often for the management of problem (challenging) behaviour in the absence of a psychiatric disorder. Care staff play a pivotal role in the prescribing process. Currently, no staff training programme exists to address the issue of overprescribing of psychotropic medication in people with ID, thus highlighting an urgent need for developing a psychoeducational programme (PEP) specifically designed to address this issue. We propose to develop a PEP for care staff using the methodology described in the UK Medical Research Council guide for complex interventions.
