• Dyslexia Cause

Dyslexia tends to run in families, and researchers have identified the genes that may be responsible for the condition.

Scientists have also found specific brain differences involved in dyslexia. Brain images show that dyslexia results from certain structural differences in the brain, particularly in the left hemisphere.

Brains of people with dyslexia show very little activity in areas known to be highly important in linking the written form of words with their phonetic components. So in order to read, people with dyslexia must develop alternative neurological pathways. They compensate by making more use of a front-brain section called Broca’s area, traditionally associated with other aspects of language processing and speech.
