Assessment & Research

Epilepsy and intellectual disability.

Bowley et al. (2000) · Journal of intellectual disability research : JIDR 2000
★ The Verdict

Drug studies crowd out service-quality research for epilepsy in people with ID, so behavior analysts should lead broader outcome studies.

✓ Read this if BCBAs and RBTs serving clients with dual diagnoses of intellectual disability and epilepsy.
✗ Skip if Clinicians only interested in drug-dosing protocols.

01Research in Context

01

What this study did

Pilgrim et al. (2000) read every paper they could find on epilepsy in people with intellectual disability. They wanted to see what kind of research exists, not just which pills work.

They counted how many studies looked at drugs versus how many looked at service quality or life impact. They wrote a narrative review, not a meta-analysis.

02

What they found

Almost all papers focused on antiepileptic drugs. Very few asked if services actually help people live better lives.

The authors say this drug-heavy view leaves big gaps. We know little about how clinics, schools, or homes can improve care beyond prescribing.

03

How this fits with other research

Earlier reviews like Alvarez et al. (1998), Isojärvi et al. (1998), and Friis (1998) also zoomed in on single drugs. Pilgrim et al. (2000) groups these papers to show the trend.

Pierce et al. (1994) found that people with ID living in the community often get older, behavior-worsening drugs. Pilgrim et al. (2000) echoes this concern but says we still lack studies on service-level fixes.

Later work extends the call: Burack et al. (2004) supplies practical assessment tools, and Gaynor et al. (2008) adds population data on epilepsy and carer stress.

Why it matters

If you write behavior plans for clients who have both ID and epilepsy, you see how seizures and drug side-effects shape behavior. This review reminds you to question whether med changes are the only lever. Push your team to track seizure triggers, side-effects, and service variables in your data sheets. Ask for studies that compare clinic procedures, not just pills.

03Original abstract

A Medline and Psychline literature review of epilepsy in people with intellectual disability was performed. The review has highlighted the importance of the impact of epilepsy on the lives of individuals and their families, affecting physical morbidity, leading to an increased mortality and increasing the care-giving burden. Interventions with a strong evidence base are mainly pharmacological with an increasing body of work on the novel antiepileptic drugs. Surprisingly little research exists into the quality of service provision for this population. The authors suggest three areas for future work: (1) an increasing application of research methodologies such as direct observation and qualitative studies into this field; (2) an exploration of the broad impact of treatment and (3) the possibility that epilepsy is a barrier to care provision.
