Seizing a link between autism and epilepsy
A new study published in the May issue of Epilepsia shines more light on the link between autism and epilepsy. The findings were picked up by multiple media outlets, including WebMD and U.S. News and World Report, where health reporter Jenifer Goodwin once again broke down the results. Researchers who looked at records of 127 patients aged 3 to 49 who were autistic and had at least one seizure over a 20-year period at the NYU Comprehensive Epilepsy Center in New York City. They found 34 percent of those patients had treatment-resistant epilepsy, meaning seizures continued despite taking medication. 28 percent were seizure-free after treatment and the remaining 38 percent could not be categorized because there wasn’t enough information to determine if their seizures were treatment-resistant or not. The average age of the first seizure in treatment-resistant epileptics was also significantly younger than those whose seizures were treatable (6 for TRE patients versus 11 for patients without TRE). Autistic TRE patients were also more likely to suffer impairments from autism spectrum disorder, as 54 percent of TRE patients had motor skills delays versus 35 percent for those with treatable epilepsy. Autistics with TRE were also more likely to experience developmental regression, which is sometimes noted among parents or other observers following their autistic children. The study’s author, Dr. Orrin Devinsky of the NYU Langone School of Medicine and director of the NYU Comprehensive Epilepsy Center, suggested autistic children may need screening for epilepsy in order to learn more about the connection between the two conditions.
Goodwin has been busy making sense out of study numbers the last couple days. Unlike her last story about a survey of parents on vaccinations and their trust with different sources, Goodwin uses more figures in the autism/epilepsy study to highlight patterns suggesting epilepsy may be more common and severe when it targets autistic people. For those of you wondering why the study sample is small, recall that autism itself is still statistically rare and some people who may be on the spectrum may not have an official diagnosis. Likewise, the number of epileptics in the world is less than one percent, meaning the statistical odds of encountering an autistic with epilepsy are slim. The results of Devinsky’s study will likely spur more investigations on the link between epilepsy and autism if none weren’t already underway, paving the way for more insights on autism and epilepsy or perhaps presenting other information that may not agree with the study Goodwin reports about.
Remember the inverted pyramid I’ve been talking about for the last few posts? It’s hard to miss in this story, with the first piece of data highlighting the percentage of autistics with TRE, then going into other data relating to autism spectrum disorder, then tying the study with the Journal of Child Neurology publication suggesting epilepsy is more prevalent with autistics than previously thought. She does grab a few quotes from Devinsky, the study’s author, but most of the story spells out the study results. That technique is common with stories on studies as reporters follow their deadlines and, depending on the location or mission plan of the news organization involved, finding the human interest source is hard to find with the low odds of a person diagnosed with both autism and epilepsy.
I’m not an epileptic, but I have read about autistic children and adults suffering from seizures in my observation of autism articles and videos. Neither autism or epilepsy may be curable, and the study only begins to excavate a relatively unexplored area of the autism spectrum. With autistics already facing prospects of sensory overload on a daily basis, making the leap to seizures isn’t a stretch. Seeing more stories linking autism and epilepsy should be expected in future media coverage, but knowing when more reports will file in will be a harder task.
