Document Summary

Composition of students with disabilities over 50% of exceptionalities: 80% of ld are reading disabilities, reading is a complex process, reading is not a natural process it is learned. Neurological dysfunction: reading disabilities are associated with minor dysfunction in the superior temporal lobe and the posterior parietal regions of the central nervous system fmri results consistently show underactivation in left hemisphere and over activation in right hemisphere. Clumping up and disorganization of brain cells in left hemisphere. Premature interruption of cell migration in the left hemisphere is associated with rd. Single-nucleotide polymorphisms (snip) on dcdc2 lead to a mutation. So its dcdc2 . right: mz twins share 100% of their genes, dz twins share 50% of their genes. If dyslexia was purely genetic we would expect both twins to be affected: but it isn"t, 60% concordance rates, why isn"t it 100%, unsure, the importance of environment.
