A Multi-Deficit approach to Dyslexia is now considered the most accurate way to understand causation.

So, the view now of Dyslexia isn’t that it’s caused by one thing, it’s not caused by reversing letters, Visually. It isn’t caused by just one thing, but it actually has several different factors that can contribute to it.

  • One is Genetics, we will talk about that. But we know that children who come from families where there is a brother or a sister or a mother or a father or even an aunt or uncle that had reading problems are much more genetically inclined toward having reading problems themselves and some genes have been identified.
  • Secondly, we know there are Brain Level Differences. We know that children with dyslexia process information differently in the brain. When we look at brain function on functional imaging process information differently than children who don’t have reading issues. We will talk about that.
  • There are these Perceptual Cognitive Level issues and those are speech sounds perception also includes visual perception also includes memory skills, working memory, auditory phonological memory skills and skills like processing speed and we will talk about that, those cognitive level differences.
  • Then there are Environmental Factors. If children come from home where there are not a lot of language exposure, they have a more limited language experience when they enter school, that can contribute as well.
