From Living Well with Epilepsy by Carl W. Bazil
"Only during the twentieth century did the medical community recognize epilepsy as a neurologic, rather than a psychiatric, disease. Society lagged behind in this recognition, continuing to view persons with epilepsy as violent or inferior. Until 1965, immigration into the United States was restricted for people with epilepsy. Many states restricted marriage under the mistaken belief that the condition would be inherited, and some even enacted involuntary sterilization laws. The last law forbidding marriage of people with epilepsy was not repealed until 1980, and the last eugenic sterilization law was in effect until 1985."
