One of Arden Berge's most surprising discoveries while he was a graduate student in meteorology had nothing to do with the weather.
"I'd been lying on the bed reading, and all of a sudden I looked up and there were paramedics standing over me," says Berge. He'd soon learn why. He'd had a seizure, and his girlfriend, Deb (now his wife), called 911 for help. Berge was taken to a hospital, where he had another seizure. He was diagnosed with epilepsy.
While epilepsy is most commonly diagnosed in children or adults over 65, it can develop at any age. The cause of the disorder can sometimes be traced to a head injury or medical issue, such as meningitis or encephalitis. But in about half of all cases - including Berge's - there is no identifiable cause.
While it was a scary diagnosis, medications made the condition manageable for Berge, who finished his degree and started his career. He adjusted to life with seizures and to the side effects of medication. Then, 33 years after his diagnosis, a trip to Mayo Clinic offered the possibility of a seizure-free life.
