Dallas scientists are unraveling cause behind sudden unexpected death in epilepsy

UC expert comments on new study to Dallas Morning News

The University of Cincinnati's Michael Privitera spoke with the Dallas Morning News on a new Southern Methodist University study that sheds new light on what might be happening in the brain when sudden unexpected death in epilepsy (SUDEP) occurs.

SUDEP is rare but results in an estimated 3,000 deaths per year.

“People can have SUDEP at any age,” said Privitera, MD, professor and division chief for epilepsy in UC's College of Medicine and a UC Health physician. He added that risk factors include uncontrolled seizures and poor adherence to medication, or when people aren’t taking their medicine as prescribed.

The study published in the journal Brain Communications identified neurons in the brain's corticolimbic system — made up of regions that govern everything from emotions to heart rate — that underlie SUDEP. When these neurons lacked a protein regulating electrical activity, called Kv1.1, mice had seizures and problems with breath and heart function. 

Privitera, who was not involved in the study, said these findings stand out because they get to the root of SUDEP, at least for one type of rare genetic mutation responsible for epilepsy.

Trial results support weekly buprenorphine treatment of opioid use disorder during pregnancy

Supported by the National Institutes of Health (NIH), researchers led by the University of Cincinnati's John Winhusen published clinical trial results in JAMA Internal Medicine that found administering weekly injectable extended-release buprenorphine for treatment of opioid use disorder during pregnancy led to higher rates of abstinence from illicit opioids than buprenorphine given daily under the tongue, one of the standard methods of treatment.
