Despite the fact that a 6-foot metal bar fell from the fifth floor of a building under construction and pierced Eduardo Leite’s skull, the 24-year-old Brazilian construction worker is doing remarkably well, The Associated Press reported.

It took doctors five hours, but they successfully removed the iron bar from Leite’s skull. This piece of metal was so powerful it pierced the worker’s hard hat, entered through the back of his skull and exited between his eyes. While the bar’s location came close to taking out one of Leite’s eyes, as well as paralyzing his entire left side, he was lucid following surgery.

However, the fact that no negative consequences have been reported following the accident is cause for alarm, according to Marla Hamberger, associate professor of clinical neuropsychology at the Neurological Institute of New York. She told LiveScience that this incident may have already led to a personality change.

"Even the fact that he doesn't seem to be bothered by it could be the effect of a frontal lesion, because most people would be bothered by that," Hamberger said. "Sometimes someone can seem functionally intact, but when you actually do some testing, there may be more of an effect than is obvious."

If individuals have survived a traumatic brain injury and are curious to see if it has changed them, they may want to consider taking a personality test.
