The little-known cause of stuttering -

Stuttering turned out not to simply be a difficult remedy of humans.

Stuttering is a fairly common handicap that has about 1% of the world's population. Do not think 1% is little, because this number is equivalent to 80 million people, which is almost equal to the entire population of Vietnam.

People with this disability often have difficulty in expressing their thoughts, thereby creating many troubles in life. For decades, there have been many medical experts who believe that the cause of stuttering is the problem of the larynx or tongue.

Even in the past there was a stuttering treatment by injecting botox into the tongue.

However, all are not the root cause of the problem. The real problem lies in the brain!

Broca region - the culprit causing stuttering

Gerald Maguire, head of the University of Riverside's Department of Neurology and Psychiatry, who is also struggling to stutter his whole life, does not believe that things simply stop at his tongue and throat. He thinks there is something deeper than that, a cause deep in the brain.

In the past, people thought it was because of tongue defects that people stutter

"People just assume this is because of the larynx or tongue. They just haven't considered the brain yet." - Maguire shares.

Today, thanks to the advancement of science and technology, more and more research (including Maguire's studies) proves that the root cause of stuttering originates from the brain.

Stuttering - the pain of so many people has finally found the cause

The human brain has a region called Broca . This region is directly related to the pronunciation ability of people in general and stutterers in particular.

A study published in Human Brain Mapping resulted in reduced blood flow when pouring into the Broca region, which caused stuttering. The more blood this decreases, the more severe the stuttering.

" Blood flow to the brain is always associated with neural activity, especially the frequency of neurons, " said co-author Jay Desai. " Our findings suggest that decreased neurological function in Broca region is the cause of stuttering."

If the cause is from the brain, what is the solution?

Unfortunately, there are currently no specific solutions. Scientists are working towards developing a drug that focuses on dopamine - a neurotransmitter that controls the reward area in the brain.

The reason comes from the hypothesis that high levels of dopamine in the brain can affect brain function, thereby stuttering.

Currently, Maguire itself is also using a drug directed to dopamine receptors to treat his stuttering.

Apparently the remedy worked, because the way he said it was really smooth. And for those who grow up with stuttering and signs of illness that appear throughout childhood - Maguire knows very well how much a good remedy can help.

" If we can develop drugs that target those areas of the brain, we can make a difference in the lives of many people - especially children," Maguire said.
