It's a problem that such glib "reasons" continue to be given.

It's essential to recognise that so many people, including some professionals, are unaware of the underlying neurological causes of difficulties  for individuals with long term reading problems or dyslexia, so they don't look for them or deal with them. At the same time, schools can only provide for a limited range of concerns and teachers can feel helpless when  a child does not improve despite effort by the child...and the teacher. (I've had that experience myself working as a classroom teacher!) 

 

This is why we focus on identifying and addressing these underlying difficulties with  holistic and scientific approaches to allow for rapid improvements which help children and adults shine through their positive abilities.
