Canadian actor and screenwriter Seth Rogen will visit Capitol Hill Wednesday to testify on the effects of Alzheimer's disease.
Rogen, known for starring in hit movies like "Knocked Up," reportedly became an advocate for victims of the disease after his mother-in-law began showing symptoms in her 50s.
"I think, until you see it firsthand, it's kind of hard to conceive of how brutal it is," Rogen told CNN in a 2011 interview. "Until I saw it, you just don't get kind of how heartbreaking it can be."
Rogen now volunteers as a celebrity spokesman and fundraiser for the National Alzheimer's Association. He will appear in this capacity before the Senate Appropriations subcommittee on Labor, Health and Human Services and Education, which governs health issues.
The hearing will examine the economic and personal toll of Alzheimer's disease and feature testimony on the state of anti-Alzheimer's research by National Institutes of Health Director Francis Collins.
Notably, Rogen won't be the only famous face on Capitol Hill this week. Actor Ben Affleck is scheduled to testify about the Democratic Republic of Congo before the Senate Foreign Relations Committee on Wednesday.
