Dyslexia is diagnosed through a series of tests of memory, vision, spelling, and reading skills. [4] Dyslexia is separate from reading difficulties caused by hearing or vision problems or by insufficient teaching or opportunity to learn. [2] Treatment involves adjusting teaching methods to meet the person's needs. [1]
The identification of these factors results from the study of patterns across many clinical observations of dyslexic children. In the UK, Thomas Richard Miles was important in such work, and his observations led him to develop the Bangor Dyslexia Diagnostic Test. [4]

Orthographic dyslexics have difficulty in storing mental representation of words, especially phonetically irregular words such as word spellings that end in -ight ...
It is also used in place of standard diagnostic test of phonetic non-word reading ability, which is mostly used to diagnose learning disabilities like dyslexia. [1] When older children and accomplished young children are slow in orally reciting texts, the individual is considered to have learning disability and is referred to correct specialists.
Definition is more in keeping with modern research and debunked discrepancy model of dyslexia diagnosis: [3] Dyslexia is a learning difficulty that primarily affects the skills involved in accurate and fluent word reading and spelling. Characteristic features of dyslexia are difficulties in phonological awareness, verbal memory and verbal ...
The Kaufman Assessment Battery for Children (KABC) is a clinical instrument (psychological diagnostic test) for assessing cognitive development. Its construction incorporates several recent developments in both psychological theory and statistical methodology. The test was developed by Alan S. Kaufman and Nadeen L. Kaufman in
Dyslexia is a common language-based learning disability. Dyslexia can affect reading fluency, decoding, reading comprehension, recall, writing, spelling, and sometimes speech and can exist along with other related disorders. [15] The greatest difficult those with the disorder have is with spoken and the written word.
