Brad Pitt thinks he has face blindness, but hasn't been tested for it. In an Esquire interview, Pitt revealed he thinks he has prosopagnosia, or face blindness.  And it's limiting his life to the extent that he doesn't go out much.

Brad Pitt says that his face blindness means people sometimes don't like him. "So many people hate me because they think I'm disrespecting them" or that people are "offended" He admitted face blindness is seriously limiting his meeting new people because even if he's  had a "real conversation" with someone, the person's face and all memory of what they look like will vanish as soon as they walk away.

And "copping" to the issue-- admitting prosopagnosia or face blindness or simply asking where he's met someone-only seems to make things worse, Pitt said. "People were more offended," he says. "Every now and then, someone will give me context, and I'll say, 'Thank you for helping me.' But I piss more people off. You get this thing, like, 'You're being egotistical. You're being conceited.' But it's a mystery to me, man. I can't grasp a face, and yet I come from such a design/aesthetic point of view."

It's the second piece of surprising medial news from the Pitt-Jolie family this week. Recently, Angelina Jolie revealed that she had a preventative double mastectomy when she realized she has a high risk of breast cancer.

Pitt says he's not going out much in order to limit the number of people he meets.

"That's why I stay at home," he confessed.

Carnegie Mellon University has offered to do brain imaging tests on Pitt for free-no word on if he's taken them up on it yet. (Although really, we're pretty sure he can pay for it...what about testing someone without a steady income or health insurance?)

People with prosopagnosia, a face blindness disease don't just have a difficult time recognizing people's faces-their brains simply can't process them. Scientists aren't sure precisely how it works, but there is thought to be a defect that means the brain doesn't pay the usual attention to faces most people's brains do.  In a normal brain, the face stands out from other details like hair or clothing. The brain pays a larger amount of attention to the face than anything else, taking a snapshot of the details and storing it in memory.

Hopefully, Pitt will be tested for face blindness and have some answers-- including, maybe, being able to go out more!
