According to a new study published in JAMA Neurology, researchers from Houston Methodist Research Institute and Case Western Reserve University sifted through Medicare data from 2016 to 2019. They found that older adults in the southeastern U.S. are significantly more likely to develop epilepsy than seniors anywhere else.

Roughly 20,000 new cases popped up in 2019, but they didn’t spread evenly. States like Louisiana, Mississippi, Alabama, Georgia, Texas, and Florida saw an explosion in epilepsy rates.
