Republican presidential candidate Ben Carson struck back against Donald Trump's recent claims that he has a "pathological" disease that cannot be cured.

During a 95-minute speech in Iowa on Thursday, the GOP front-runner hailed a barrage of attacks against Carson, who has been doing increasing well in election polls over the last few weeks. In addition to equating Carson's childhood "pathological temper" to the illness of a child molester. Trump questioned the retired neurosurgeon's religious awakening, which he describes in his book "Gifted Hands." Trump also berated voters who are supporting Carson.

"How stupid are the people of Iowa?" said Trump at a rally at Iowa Central Community College, reports The New York Daily News. "How stupid are the people of the country to believe this crap?" he continued, referring to Carson's claim that he was delivered from his violent temper through prayer in his book.

Trump went on to say that Carson's own descriptions of his "pathological temper" as a young man is a "big problem because you don't cure that. That's like, you know, I could say, they say you don't cure -- as an example, child molester. You don't cure these people. You don't cure the child molester." Trump added that "pathological is a very serious disease."

In response, Carson dismissed Trump's attack and alluded that the reality TV star does not understand the meaning of "pathological."

"It's not the kind of dialogue that I would ever engage in and I'm hopeful that his advisers will help him to understand the word pathological and know that that does not connote incurable," Carson said on Friday, according to CNN. "It simply describes something that is highly abnormal and something that fortunately I've been able to be delivered from for half a century now."

The famous doctor also told reporters that he would like to focus on real issues rather than Trump's attacks.

"Now that he's completed his gratuitous attack, why don't we press on and deal with the real issues," Carson said. "That's what the people of America are concerned about, not so much politics as usual, politics of personal destruction -- that's what the American people are sick and tired of."
