It's just like Munchuasens except people are going in to fake having a condition so they can get diagnosed. I don't understand why people would want to do that. I have never heard of any case. Do they do it so they can get attention and sympathy from people or just so they have an excuse to be a jerk and all?
But there are also diagnosed people out there who do use their condition to gain sympathy or attention and complain about their real problems they don't want to fix. They just want sympathy and attention.
I have also heard of people faking learning disabilities just so they get more time on their school work or get their work modified, etc. and people faking other conditions so they get things they want like accomodations in public. I am sure they always get caught because it's so hard to fake something but people like us aren't qualified to say someone is faking it. Just because someone looks normal in a wheel chair doesn't mean they are faking it. Just because someone parks in the handicapped spot and the person doesn't look disabled doesn't mean they aren't disabled.
I remember in South Park where Cartman faked having Tourettes so he have an excuse to be even more of a jerk and get away with saying very offensive things and get away with ripping on Kyle for being Jewish. I am sure there are people out there who do fake Tourettes just so they can get away with saying profanity in public and insulting people and no one will know that person is faking it except a doctor. I am sure some people would know because if they know someone who has TS or they have it themselves, they would see the person's traits are too exaggerated so they would know the person is faking it.
