Garrison Keillor, host of “A Prairie Home Companion,” suffered a brain seizure over Memorial Day weekend, but says he’ll still perform this weekend.

In a post on his Facebook page, Keillor revealed he had the seizure after performing two shows in Virginia last weekend.

He was treated in a local emergency room and then traveled to the Mayo Clinic in Rochester, Minn., for further tests, the post said.

He wrote that the Mayo visit left him feeling fortunate. He saw an MRI scan that showed damage caused by a previous stroke near the language centers of his brain.

Keillor said a doctor prescribed an anticonvulsant that makes him feel lethargic. However, he intends to perform the remaining five shows in this season before he steps down as host.

A Prairie Home representative said Keillor was en route to this weekend’s show in Atlanta.
