From The New York Times:
One was a middle-aged man who refused to get into the shower. The other was a teenager who was afraid to get out. The man, Leonard, a writer living outside Chicago, found himself completely unable to wash himself or brush his teeth. The teenager, Ross, growing up in a suburb of New York, had become so terrified of germs that he would regularly shower for seven hours. Each received a diagnosis of severe obsessive-compulsive disorder, or O.C.D., and for years neither felt comfortable enough to leave the house. But leave they eventually did, traveling in desperation to a hospital in Rhode Island for an experimental brain operation in which four raisin-sized holes were burned deep in their brains. Today, two years after surgery, Ross is 21 and in college. “It saved my life,” he said. “I really believe that.” The same cannot be said for Leonard, 67, who had surgery in 1995. “There was no change at all,” he said. “I still don’t leave the house.” Both men asked that their last names not be used to protect their privacy.
