Oh, yeah, another bonus item:
The treatments don’t seem to have been working, unfortunately.
Marty Bergen? You could compare him with later athletes like, say, Jimmy Piersall (bipolar) or Defensive End Lionel Aldridge (schizophrenic), who had treatment available.
Holy shit. We’re looking for generically feel-goody uplifting, so I think that one I’ll have to give a pass on.
Then just go with Aldridge, who eventually rose above his schizophrenia and became a public speaker/advocate for the homeless & mentally ill.
And went on to coach baseball at Gallaudet.
Wow. Tennis, even doubles tennis, on one leg. Just wow.
“Dummy” Hoy played for several baseball teams in the 19th century. His deafness led to the invention of umpires’ signaling balls and strikes. Speaking of Gallaudet, the field there is named for him. Also speaking of Gallaudet, they invented the football huddle so no one could read their hand signals.
David Garrard, QB for the Jacksonville Jaguars, has Crohn’s disease.
Six fingers on both hands, and six toes on each foot. However, the extra finger evidently does not affect his pitching, since it doesn’t touch the ball.
I love his nickname: El Pulpo, Spanish for “The Octopus.” 
Martel Van Zant. Deaf CB who played at Oklahoma State and is now in the arena league.
Great guy.
Alex Zanardi lost both his legs in an accident in a CART race in 2001 and has returned to compete in Touring cars.
This is a good time to highlight Ken Green, PGATour Golfer. Ken Green had a journeyman career in the 80’s and 90’s. Winning a couple of tournaments, and even playing on a Ryder Cup Team. But he was a non-conformist on Tour, and was not very popular with the fans.
He turned 50 a couple of years ago and was trying to get status (w/ little success) on the Champions Tour, the PGATour for golfers.
Last summer, he was in an RV (might have been driving) when it got into a horrific accident. He was critically injured, and Doctors had to amputate his right leg. His brother and girlfriend were killed in the wreck. (as was his treasured dog).
And then, even more tragedy cam to Greean as this past January, his son was found dead at college, he apparently committed suicide with pills and alcohol.
After the accident, Green got fitted with a prosthetic leg and has been practicing very hard to get competitive in golf and still has hopes of getting status on the Champions tour.
This week, the Champions Golf Tour has one of their special events of the year, a team competition. Mike Reid, another journeyman pro of Green’s era, asked Green to play as his partner. yesterday they shot a respectable round and a T17 after round 1.
Don’t see him mentioned, but Rocky Blier was wounded in Vietnam, awarded a Bronze Star and a Purple Heart, but told he’d never play football again. Went on to earn 4 Super Bowl rings.
Brian McKeever, a cross-country skier from Canada, suffers from Stargardt’s disease, which cost him his vision. Despite this, he managed to qualify for a spot on Canada’s cross-country skiing team for the 2010 Winter Olympics. He would have been the first ever person to compete in the Winter Paralympics and Winter Olympics in the same year, but the team’s coaching staff gave his spot in the 50 km race to another skier.
If Tourrette’s counts, there’s Everton & U.S. national team goalkeeper Tim Howard.
Mixed martial artist Matt Hamill is deaf.
As did Rolf Benirschke, placekicker for the San Diego Chargers in the late 1970s and early 1980s. He missed most of a season due to it.
Jim McMahon, quarterback for a number of teams (most notably the 1985 Super Bowl Bears) suffered a childhood eye injury (he accidentally stabbed himself in the eye with a fork). I’ve read various accounts of how severely damaged his vision in that eye was; at a minimum, it became very sensitive to light (which is why he always wore a dark visor).
Almost forgot Bo Jackson. At one time a star player in both the NFL and MLB, he suffered a hip injury as a running back for the L.A. Raiders in a game in 1991, which ultimately led to him needing to have his hip replaced. He was able to come back as a baseball player, playing two more seasons.
