Brad Pitt appears on the cover of the June/July issue of Esquire and gives an insight into why he does not recognize  people he has previously met or even had "real conversations" with.

Brad Pitt is not being "egoistical" or "conceited," but the star couldn't help sharing with the magazine that he has difficulty in recognizing people's faces despite having had "real conversations" with them. He suspects he may be suffering from prosopagnosia, or face blindness, where the ability to match names to people's faces gets complicated. But the 49-year-old actor is willing to have it checked.

"So many people hate me because they think I'm disrespecting them," Pitt told the magazine. "I took one year where I just said, This year, I'm just going to cop to it and say to people, 'OK, where did we meet?' But it just got worse. People were more offended. ...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. I am going to get it tested."

Pitt's acceptance of the face perception disorder led to an invitation from Carnegie Mellon University to be examined by Marlene Behrmann, a neuroscientist, professor of psychology and a member of the Center for the Neural Basis of Cognition within the university's Dietrich College of Humanities and Social Sciences. Behrmann said in a university's news release that Carnegie Mellon is among the very few places to "test for face blindness and perform the brain imaging in our state-of-the-art imaging center."

Prosopagnosia is a neurological disorder, which affects one in every 50 people, according to a study in the American Journal of Medical Genetics. In this disorder, the area of the brain that activates response to faces is impaired.

"Carnegie Mellon has a longstanding history for embracing a full-system account of the brain. We have the computational tools and technology to push further into looking past one single brain region," Behrmann added.

"If Mr. Pitt would be willing, we would be honored to image his brain for diagnostic purposes."

The "Moneyball" actor told the magazine that he is happier than ever with his life around his family and friends. "I have a handful of close friends and I have my family, and I haven't known life to be any happier," the actor said. "I'm making things. I just haven't known life to be any happier."

The June/July issue of Esquire magazines will hit the newsstands May 31.
