<unk>  is a  learning disability that manifests primarily as a difficulty with written language, particularly with reading and spelling. It is separate and distinct from reading difficulties resulting from other causes, such as a non-neurological deficiency with vision or hearing, or from poor or inadequate reading instruction. 
Evidence suggests that<unk>  results from differences in how the brain processes written and/or verbal language. Although<unk>  is the result of a neurological difference, it is not an intellectual disability.<unk>  occurs at all levels of intelligence; sub-average, average, above average, and highly gifted.
