Dyslexia is a learning disorder arising from abnormality in the part of the brain that organizes written information. Dyslexics have difficulties in reading and writing. The disability may include words and not letters, figures and not letters, and so on. Symptoms include skipping words or lines when reading or writing, changing or reversing letter or number sequences, dizziness when looking at words, and daydreaming. Dyslexic children may be gifted in other areas; for example, they learn to walk earlier than non-dyslexics.
Five to 15% of children have some form of dyslexia.
