Developmental dyslexia, or specific reading disability, is a disorder in which children with normal intelligence and sensory abilities show learning deficits for reading.
A common misconception with the term is that parents and others may think that âdyslexiaâ is a cause for a childâs difficulty learning to read and are unaware of the actual meaning of the term. Dyslexia is a descriptive term, which means an impairment in the ability to read. Contributing to the misinterpretation of the term âdyslexiaâ, are recent media reports about dyslexia and about researchers who are beginning to identify anatomical and chemical differences in the brains of good and poor readers.
