陌陌站街号哪里买Stuttering 101: Don't make fun of thi
作者: 发布日期:2020-08-23
Stuttering, or stammering, occurs when a person repeats or stumbles over a sound, syllable or word. Certain syllables may be repeated or prolonged, words escape in fits and starts, and can at times be accompanied by involuntary facial tics, fist clenching and rapid blinking.
 
陌陌号购买Many saw an example of that on the final night of the Democratic National Convention when a 13-year-old boy shared with the world the support he has gotten from the party's 2020 presidential nominee, Joe Biden.
"He told me that we were members of the same club: We stutter. It was really amazing to hear that someone like me became vice president," said Brayden Harrington in the video recorded for the convention.
He told the story of how he met Biden at a New Hampshire campaign rally and how the former vice president took him backstage and showed him how he prepared scripts for public speaking.
"He showed me how he marks his addresses to make them easier to say out loud. So I did the same thing today," Brayden said, flipping around the piece of paper he was reading to show the markings on his speech.
"I'm just a regular kid, and in a short amount of time, Joe Biden made me feel more confident about something that's bothered me my whole life," Brayden said.
According to the Stuttering Foundation, 70 million people worldwide stutter, which is about 1% of the population. In the United States, that's over 3 million Americans. Interestingly, stuttering affects four times as many males as females, although it is not fully understood why.
It's in the genes
陌陌站街号Sixty percent of those who stutter also have a family member who stutters, studies have found. But it was not until 2005 that scientists discovered why. Today we know that mutations in four genes contribute to about 20% of all cases of stuttering, and science is searching for more.
Those genes affect a part of the brain that controls "intracellular trafficking" — a relatively new understanding of how certain molecules inside a cell direct traffic along various neural pathways. These genes are also being studied in connection with Parkinson's, Huntington's and even Alzheimer's disease.
A former researcher at the National Institute on Deafness and Other Communication Disorders, Dennis Drayna, spent much of his career researching the causes of stuttering because it runs in his family. Now retired, he explained how the genetic mutations impact speech in a previous interview with CNN.
"These mutations affect a process inside cells that degrades things that the cells don't need anymore," Drayna said. "This process is called the garbage can, or more like the recycling bin, of the cell. When this process gets interrupted, the cell goes haywire, and that causes problems."
陌陌女号Genes can't explain all cases of stuttering, however. There could be physical issues that contribute, such as speech sensory and motor coordination, and of course having a stroke, traumatic brain injury or other brain disorders.
