Scientific explanations of Dyslexia
This video from Understood.org explains the research that shows the difference between dyslexic and non-dyslexic brains using brain imaging.
This allows researchers to reason which interventions are effective and which aren't, as well as showing possible strengths such as dyspraxics having a better than average ability to see 'the big picture'.
Even though almost 10 mins long, well worth watching.
