First the family members should understand exactly what dyslexic is and why it happens. Second the dyslexia can be corrected, which eliminates the problem all together. A parent or other family member could help the dyslexic get through the correction steps in section four of the book. An interesting question that has both a 'yes' and 'no' answer. We are becoming more aware of problems like dyslexia.
Every year there are more problems like dyslexia, more names and types of problems.
At the same time there are new names for behavioral problems that are not recognized as having their root in the frustration of dyslexia. In this regard the trend is moving in the wrong direction. There is a real lack of understanding of why people have unwanted behaviors in the first place. It is not a child, struggling for whatever reason, that is the problem, it is that we're looking to the wrong place for a definition or an answer. I believe that is a real problem.
