dyslexia as being a visual problem

“My child can’t read… and the school told me its because he has dyslexia… he reverses his letters and they said that he gets the letters all jumbled. They said that it had something to do with his vision and as a result, he can’t read. Now what? Do we get an eye examination?"

Hmmmm… letters jumbled up meaning that you can’t raed? Are you albe to raed this eeven thugoh the ltteres are all mxied up? Aoccdrnig to rscheearch at Cmabrigde Uinervtisyity, ltteer odre deos not mttaer… the iprmoatnt ptar is taht the frist and lsat ltteer be in the rghit pclae… the rset can be a taotl mses and you can sitll raed it wouthit a porbelm. So… is dyslexia related to letters being jumbled up? Is dyslexia a disturbance of visual configurations of letters?

Research (see Dr. Jack Fletcher) among children reveals that phonetic or speech sounds processing is the most commonly the primary underlying disorder in dyslexia. Other contributing factors to low achievement in reading (or dyslexia which means a disturbance in reading) include low vocabulary and limited experience with reading (ie., few repetitions, insufficient time spent reading, etc.). Need to rule out reduced visual acuity as a contributor to slowed reading, headaches in the afternoon… by all means, please get an eye examination. But, dyslexia as being a visual problem? Hmmmm… maybe not.

So, how do I know if my child has dyslexia”? Well, dyslexia simply indicates a disturbance in reading… Is your child reading significantly below the level of his or her peers? If so, then he or she has dyslexia or a reading disorder. Unfortunately, dyslexia or the formal diagnosis of a reading disorder does not communicate anything beyond the symptom description. The real task is identification of factors that contribute to reading problems. In the past, various models have been employed to classify reading disorders with the discrepancy model holding court for the past 25+ years. The discrepancy model defines a reading disorder in terms of a significant discrepancy between reading achievement (lower) and abilities (higher) with some suggestion or assumption of a significant verbal (lower) vs. perceptual-motor (higher) processing discrepancy.

However, recent reviews of research (see Fletcher, J.M., Francis, D.J., Morris, R.D. and Lyon, G.R.. “Evidence-based assessment of learning disabilities in children and adolescents”, Journal of Clinical Child & Adolescent Psychology, 2005, Vol. 34, No. 3, Pages 506 – 522) indicates that this model has serious psychometric problems (meaning research cannot reliably replicate it). More recent work suggests that, while low reading achievement is the critical element for classification as a reading disorder (by definition), an evidence-based assessment must include an analysis of reading components (ie., see, discriminate letters, associate letters to sounds, put sounds together to make words, put words together to form sentences/ideas, formulation of themes and output) so that interventions are directed towards the weakest link in the chain of reading.

In addition, the work of Fletcher, et. al. (2005) calls for “a stronger underlying classification that takes into account relations with other childhood disorders” including a need for assessment of abilities (hardware), skills (acquired) and coping resources (ie., family support, teachers, educational instruction, etc.).

Einstein’s Relativity

“I am a foster parent. My (foster) child appears angry with periods of rage and depression along with acting out, aggression… he can’t sleep at night, can’t sit still… and has basically no friends because he plays too rough. His family background is a mess… father is incarcerated, mother has a long drug history with multiple paramours, alcohol abuse, domestic violence. We have been told that he as ADHD, ODD and bi-polar disorder. He has "failed" trials on three different psychostimulants and now is taking some kind of cocktail that includes three medications at one time. Are his problems biological or environmental?” Hmmmm…

… this may take a minute to formulate a theoretical background… but please be patient with me… Einstein’s “Theory of Relativity” boiled down to its child-like essence goes something like this. As a boy, young Einstein would sit along the railroad tracks and watch the trains go by. In his book, Relativity, he recalls wondering what would happen if someone threw a ball up in the air while riding on a moving train. What would it look like? Well, if you were on the moving train the ball would travel in an arc … and one could actually construct a mathematical equation that would define the arc. But, if you were sitting beside the train tracks, the ball would travel straight up and down in a line and you could construct a mathematic equation that would define the line. Both are mathematical truths! So, which is true? Does the ball travel in an arc or line? The answer… it depends on the relative position of the observer.

Hmmmm… what does that have to do with neuropsychology in general or your child, in particular? Is a symptom/problem related to a physiological disorder (mass) or a psychological disorder (energy)? The answer? Yes… it is both… any symptom/problem will have both physiological (brain/body) and psychological (energy/spiritual) components. The implication is that a holistic approach that seeks to understand both physiological and psychological contributions to symptoms is critical… and that interventions must necessarily consider both physiological and psychological factors. The physician who treats only the body is a fool as equally as the psychologist who only treats the psyche… the mind and body are simply two aspects or perspectives of the same person… and treatments must consider both avenues.

What does this have to do with your child? It means that your activities, relationship, home environment, emotional tone, etc. are as critical to your child’s healing as the medication. Oftentimes we look to wizards (ie., physicians, psychologist, etc.) to treat the body and feel powerless or impotent to affect outcomes. Your efforts are central to healing!!!
