Researchers have suspected that certain languages expose the language disorder dyslexia while others allow dyslexics to compensate. Now a multinational team of researchers has used positron emission tomography scans to observe brain activity in British, French, and Italian adults while they read. Regardless of language, the team reports on page 2165, people with symptoms of dyslexia showed less neural activity in a part of the brain that's vital for reading, indicating that the difference in the prevalence of the disorder among different countries could be attributed to language.
