According to AOL News' "The Daily Pulse":
Although Roberts has had other seizures, in 2001 Roberts described his health as "excellent" according to Senate Judiciary Committee records.
"It's my understanding he's fully recovered, said Christopher Burke, a spokesman for Penobscot Bay Medical Center, where Roberts was taken.
Roberts, 52, was taken by ambulance to the medical center, where he underwent a "thorough neurological evaluation, which revealed no cause for concern," Arberg said in a statement.
Roberts had a similar episode in 1993, she said.
Doctors called Monday's incident "a benign idiopathic seizure," Arberg said. The White House described the January 1993 episode as an "isolated, idiosyncratic seizure.
"A benign seizure means that doctors performed an MRI and other tests to conclude there was no tumor, stroke or other explanation.
In addition, doctors would have quickly ruled out simple explanations such as dehydration or low blood sugar.
By definition, someone who has had more than one seizure without any other cause is determined to have epilepsy, said Dr. Marc Schlosberg, a neurologist at Washington Hospital Center, who is not involved in the Roberts' case.
Whether Roberts will need anti-seizure medications to prevent another is something he and his doctor will have to decide.
