Did Patricia Arquette have a stroke in real life or is this just part of her role as Alicin on Medium?

Patricia Arquette (born Patricia T. Arquette on April 8, 1968 in Chicago, Illinois) did not have a stroke, only the character she played on the TV series Medium (2005-2011) had a stroke; what you witnessed was simply very good acting. This shouldn't be too surprising as acting appears to run in her blood; her grandfather, Cliff Arquette, played TV character "Charlie Weaver," & her siblings are actors Richmond Arquette, Alexis Arquette, David Arquette & Rosanna Arquette. Patricia is a divorced mother of 1.
