Document Summary
Composition of students with disabilities over 50% of exceptionalities. 80% of ld are reading disabilities (1 or 2 kids per class inclusive classrooms) Reading is a complex process reading disability/dyslexia different than a bad reader (problem processing sounds can"t remove b from cucumber-problem with phonological processing) too much processing, no comprehension. Reading is not a natural process it is learned (phonemes- th , manipulate all 44 of them to make 100,000 words) Neural ectopia clumping up of cells, information hits a hiccup which causes processing problem hemisphere. Clumping up and disorganization of brain cells in left. Premature interruption of cell migration in the left hemisphere is associated with rd. Genes - dcdc2 mutation (faulty instructions/snip) on this gene is thought to be associated with dyslexia responsible for left hemisphere cell migration. Single-nucleotide polymorphisms (snip) on dcdc2 lead to a mutation. Mz twins share 100% of their genes. Dz twins share 50% of their genes.
