What Causes Dyslexia?

Specialist doctors and researchers do not know exactly what causes dyslexia. According to the results of the studies and the evidence obtained, the probability of dyslexia being genetic is quite high. Two important factors are highlighted as the cause of dyslexia. These:

  • Genetic Causes: A team at Yale School of Medicine found that defects in a gene known as DCDC2 are associated with problems in reading performance.

  • Acquired Dyslexia: A small minority of people with dyslexia have acquired the condition after birth, usually due to a brain injury, stroke, or other type of trauma.


Dyslexia is the most common learning disability, according to University of Michigan Health department experts. In fact, 80 percent of students with learning disabilities have dyslexia.
