Dyslexia affects reading, spelling, writing, memory and concentration, and sometimes maths, music, foreign languages and self-organisation. Some people call dyslexia 'a specific learning difficulty'. Dyslexia is caused by a difference in the part of the brain that deals with language. There is evidence gathered from brain imaging techniques that dyslexic people process information differently. Dyslexia tends to run in families.
Dyslexia continues throughout life.
Dyslexia occurs in people from all backgrounds and of all abilities, from people who cannot read or write to those with university degrees. Dyslexic people may have creative, artistic, practical skills. They can develop strategies for their areas of difficulty. Dyslexia is a puzzling mix of both difficulties and strengths. It varies in degree and from person to person.
