Causes of Dyslexia

Although there are many theories about the cause of dyslexia and other learning difficulties, no theory has been proven. There is evidence that a family history of dyslexia or reading difficulties may be a factor. Being born premature may also be a factor (1).

Most experts believe that dyslexia is a disorder of the language function of the brain, leading to problems with processing auditory and visual information.

Some theories suggest that the learning difficulties are due to one side of the brain being more dominant than the other. This may explain why many dyslexic people are very creative, musical or sporty.

Dyslexia is not the result of emotional difficulties, limited intelligence or laziness.
