Autism and epilepsy (and tuberous sclerosis?) in two pre-adolescent boys: neuropsychiatric aspects before and after epilepsy surgery.
Epilepsy surgery can spark big autism gains, but watch for puberty-triggered relapse.
01Research in Context
What this study did
Doctors tracked two boys who had both autism and hard-to-control seizures.
Both had epilepsy surgery to remove the seizure focus.
The team watched how autism traits changed after the operation and into puberty.
What they found
One boy spoke more, played with others, and lost his autism diagnosis after surgery.
The other boy did well at first, but his seizures and autism traits returned during puberty.
Results were mixed: surgery can help, but gains may not last for everyone.
How this fits with other research
MDiemer et al. (2023) later tested a newer method—responsive brain stimulators—in 19 autistic children with drug-proof epilepsy.
Most kids had fewer seizures and better behavior, showing the idea still works with gentler tech.
Repp et al. (1987) and Billstedt et al. (2005) followed larger groups through puberty and adulthood.
They found early IQ and speech predict long-term outcome, matching the relapse seen in the lower-functioning boy.
Together, the papers say: cutting or calming seizures can sharpen skills, but early ability and puberty still shape the final path.
Why it matters
If you serve a client with both autism and drug-proof epilepsy, share this case with the neurologist and family.
Stress that surgery or neurostimulation may unlock language and social gains, yet puberty can stir relapse.
Plan extra assessments at age 11–13 and keep ABA targets ready to rebuild any lost skills.

03Original abstract
We report on two pre-adolescent boys with a combination of severe seizure disorders and severe-moderate autism who underwent brain surgery for their epilepsy at the ages of 9 and 10 years, respectively. Both boys became seizure-free and initially improved dramatically with regard to autism symptoms. One of the boys continued to improve, but the other had a relapse to his pre-operative state in conjunction with his pubertal growth spurt. Several years after surgery, one of the boys remained much improved with respect to his autism. The other subject showed some improvement with respect to self-injury and aggression, and had slightly lower scores on screens for autism symptoms than in the year preceding epilepsy surgery. The histopathological examination of the brain tissue that was removed at surgery suggested a diagnosis of tuberous sclerosis in both cases.
