Question: For Martin Sheen: I was very excited by the episode where we found out that your character has MS. My mom has MS and it was great to see it addressed in prime time. Will there be more episodes that address this issue and what do you think will happen?Martin Sheen: The President is gradually going to have to come to grips with the debilitating effect it is having on his body. Depending on how long the show is on the air, we will see the full effects of the disease. If we get the full term. Meaning I would finish 3 years in the 1st administration. If I am reelected it would be 7 years. By then the President would be in a wheel chair is going to be very very interesting.

"Part of what we're playing throughout the fall is the growing unease with the leading candidates that show up for the Democratic nomination," [John] Wells says, "and should the White House try behind the scenes to get more involved in seeing if a better candidate should be put forward?"

Bartlet, meanwhile, is pondering his legacy and feeling a "growing unease" with the prospective Democratic candidates."That, we think, is interesting territory, when you look at who is likely to replace you and realize that you need to stay above the fray and, at the same time, you're not happy with the direction the election is going in," Wells says.
" In 'West Wing' time, it's more"

For a while, Pat Gove thought Josiah Bartlet was getting off easy.
That changed when Bartlet - the fictional president on the NBC drama "The West Wing" - started having symptoms she recognized.
Gove and Bartlet have something in common: Both have multiple sclerosis (MS).
The disease - a chronic degenerative disease affecting the central nervous system - only had caused political fallout for Bartlet until a few weeks ago. Now the character, played by Martin Sheen, is shown suffering the disease's many physical effects, including numbness, paralysis and loss of vision.
"Now it's getting more into how MS really is," the 54-year-old Mason woman says.
Multiple sclerosis patients and their doctors say the series is offering a realistic portrayal of the disease's unpredictable progression.
In the Dec. 1 episode, Bartlet reports losing vision in one eye. Last Wednesday, the character slowly lost feeling in his limbs, and was paralyzed from the neck down for some hours.
A trailer for tonight's episode (9 p.m., Channels 5, 2) shows Bartlet still partially paralyzed as he begins a crucial summit with China.
Dr. Michael Schmerler, a neurologist with Riverhills Healthcare, says the symptoms shown so far track with textbook examples of how MS affects patients.
"We see these symptoms, unfortunately, all too often," Schmerler says.
Nancy Corbett, 41, a Newport artist, has suffered the same vision problems and paralysis as Bartlet.
The series "is pretty accurate for most MS patients," Corbett says.

On "The West Wing," Sheen plays a president who finds ways to do his job despite multiple sclerosis. A University of California consultant has advised Sheen on how to play the struggle with the disease."What she told me was to be subtle. I can have many ups and downs," he said.
Subtle and optimistic. "(MS) patients see the light at the end of the tunnel," Sheen said.
Sheen isn't an official spokesman for MS because, unlike his character, he doesn't have the disease.

"In terms of just getting nominated [for Outstanding Drama Series Emmy], we send out three episodes that show the diversity of the cast and strong storytelling, but we don't send shows that are too similar even if they're very good," executive producer John Wells explains.
