Day and Reagan would co-star together again in “The Winning Team” (1952). Reagan played the part of Grover Cleveland Alexander, a hall of fame major league pitcher who struggled against alcoholism, epilepsy and myopia (double-vision). Alexander pitched for the Philadelphia Phillies, the St. Louis Cardinals and the Chicago Cubs.
Found this here.
Found more about the film here at a Doris Day site.
I have not yet seen the film, but the links above suggest that there may not have been any mention of epilepsy or seizures in the film based on the story of Grover Cleveland Alexander.
