Brain scans can detect preschool children with dyslexia, even before they begin to read, the researchers said.
An American research team has found that it has seen scans in adult situations. And these differences in the brain may be a cause, not the consequences of dyslexia, something unknown until now reported by the "Journal of Neuroscience."
The scan may allow early diagnosis and intervention, experts hope. A part of the affected brain is called an arcuate fiber bundle. Of these, 40 schools entered the children. They studied and they discovered some areas of the brain that had shrunk, dealing with the sound and language of the text.
In the study, the curved volume on the left had poorly pre-read test results with particularly strong links. The left bow-shaped fiber bundle connects the speech production to another area of ​​the brain used to understand written and spoken language. A larger, more organized bow-shaped fiber bundle can help the communication between the two regions, the researchers said.
Professor Gabrielle said: "We already know a lot about this brain area, so this is a good candidate." A few years ago, American doctors described the situation of children with dyslexia who developed radiation therapy for brain tumors. The same brain area.
