Differences in Brains of People with Dyslexia

Dyslexia causes problems with reading and writing and is the most commonly diagnosed learning disorder in the United States. Researchers have discovered that people with this condition have disrupted network connections in their brains. Using functional MRI, the research team found that individuals with dyslexia have less connectivity between a number of the brain regions used during the reading process when compared to MRI scans of people without dyslexia. Study author Dr. Emily Finn writes, “Compared to typical readers, dyslexics had weaker connections between areas that process visual information and areas that control attention,suggesting that individuals with dyslexia are less able to focus on printed words.”
