ABA Fundamentals

A behavior analysis approach to high-rate myoclonic seizures.

Cataldo et al. (1979) · Journal of autism and developmental disorders 1979
★ The Verdict

A short break after each jerk cut seizure rate even when drugs could not.

✓ Read this if BCBAs working with clients who have drug-resistant myoclonic or habitual jerks.
✗ Skip if Clinicians whose clients already have well-controlled seizures on medication.

01Research in Context

01

What this study did

Doctors watched one teenage boy who had dozens of myoclonic jerks every hour. Drugs had failed, so the team tried two simple rules. If a seizure happened in the quiet room, they turned the lights off for 30 seconds. If a seizure happened on the ward, the boy had to sit still on a bench for three minutes.

02

What they found

Both rules quickly cut seizure rate. The brief light-out and the short bench break worked even though medicine had not. Staff could see the drops on their daily tally sheets.

03

How this fits with other research

Pickering et al. (1985) later showed the same thing: timeout beat dextroamphetamine and thioridazine in three kids with severe behavior. The pattern is clear — behavioral consequences can outperform pills.

Arcieri et al. (2015) sounds like it clashes. They found that 39% of "seizures" in disabled children were misdiagnosed. Maybe the 1979 jerks were not true epilepsy. Even if they were habits, the timeout still reduced them, so the treatment is useful either way.

Burack et al. (2004) give us the tool to check: pair EEG data with real-time behavior logs. Use their method before you start timeout so you know what you are really treating.

04

Why it matters

When meds fail, a quick consequence can still give relief. You do not need fancy gear — just a dark corner or a quiet bench. Start with a simple count of events, add a brief break, and watch the numbers fall. If the drops are big, you have a low-cost option that beats adding more drugs.

03Original abstract

Epilepsy represents a serious medical and social problem. In the majority of cases, seizures are successfully managed by a variety of anticonvulsant medications, even though these drugs may potentiate significant physical and developmental side effects. A small group of studies to date have offered evidence that behavioral procedures can successfully manage some seizure disorders and are particularly desirable treatment choices when seizure disorders are intractable to drug management or when drug side effects are to be avoided. The present case adds to this small but growing group of studies in that it demonstrates the use of behavioral procedures in the analysis and treatment of high-rate myoclonic seizures. Seizures were evaluated on a hospital ward and in a controlled experimental setting. The data indicated a variable rate of seizures across days and activities and a reduction of seizure frequency in the controlled setting when time-out was made contingent on seizures. A program of contingent rest' was then applied on the hospital ward that demonstrated a reduction in myoclonic seizure frequency and the apparent prevention of several grand mal episodes. An observer calibration procedure showed high correspondence between behaviorally and physiologically recorded seizures. A discussion of issues in behavioral medicine research follows.
