Chronic neurological disorder causing inability or great difficulty in learning to read or spell, despite normal intelligence. It inhibits recognition and processing of graphic symbols, particularly those pertaining to language. Symptoms, including very poor reading skills, reversed word and letter sequences, and illegible handwriting, usually become evident in the early school years. With early recognition and specialized approaches to teaching reading, most dyslexics can learn to read. Anomalies have recently been found in reading-related pathways in the brains of dyslexic persons.
