Politico title Brain scientists find a cure for Alzheimer’s article The brains of some of the most intellectually gifted people in the world have been found to be incapable of comprehending language, a new study suggests.
The findings provide a unique window into how the brains of the world’s smartest people develop and develop in their twilight years.
Brain scientists are now testing new techniques to determine whether a person can understand a sentence that has been composed with words that are not part of their language.
The findings, published Wednesday in the journal Nature, are likely to boost efforts to improve language comprehension and help prevent dementia, a disease that affects an estimated one-third of the population.
In the study, scientists looked at the brains from a group of nearly 400 people who were given a task that was difficult to understand: learning a foreign language.
The researchers used a new imaging technique to look at the connections between a person’s brains and the brain tissue around them.
The people who had trouble with understanding the language were found to have fewer connections between the brain and the white matter in the region known as the thalamus, the brain’s structure that carries signals from nerve cells to the brain.
The thalamic white matter contains connections between nerve cells.
White matter is the network of nerve cells that runs along the nerve fibers that control the muscles in the body.
Scientists are still trying to understand why the thalsus loses its connection with the white outside its walls during language learning.
One theory suggests that as a language grows, the thalamamus is less active, leaving more connections between white matter and the thalos, or brain matter, which is more active.
But that hypothesis has not been tested in human studies.
Researchers also have not been able to test the brain structure that develops in a person with dementia because of the difficulty in learning new words, said study co-author Dr. David Deutsch, a professor of neurology at the University of Washington.
It’s likely that the thalo is just one of many brain structures in the brain that have not developed in the same way as other brain structures, Deutsch said.
Dr. Mark Biedermann, a cognitive neuroscientist at Harvard Medical School and a co-investigator on the study with Deutsch and his team, said the findings could help scientists understand how language develops.
“We’re finding that the brain develops in this way, and the structure that is developing is different from the one the person is exposed to,” Biedermanso said.
“If you have a language that you can understand, it’s probably going to be different from your native language.
It could be the case that you are not very good at understanding this language, but you have very good white matter connections.”
Scientists think language development may take place differently in people with dementia than people without dementia, since language is not a direct result of the brain chemistry, Deitsch said.
They believe that the underlying mechanisms are different.
For example, if you have Alzheimer’s disease, you might be more likely to have difficulty processing information that has to do with a person who has lost their language, Biedermans said.
But if you are healthy, you probably will have an easier time.
More research is needed to determine the exact nature of the language learning impairment in these individuals.
If you or anyone you know is experiencing any of the following symptoms, talk to your doctor: loss of ability to comprehend words; difficulty learning new sentences; difficulties understanding unfamiliar speech; and difficulty in speaking.
