Dyslexia and Science (2)

According to the International Classification of Psychological Disturbances ( ICD-10, World Health Organisation) there is a differentiation between a reading and writing disturbance ( F81.0), an isolated reading and writing disturbance (F81.1) and a combined disturbance of schooling/educational skills (F81.3).

It is difficult to consistently diagnose dyslexia before a child begins school. However, many dyslexic individuals have had a history of difficulties that began well before kindergarten. Children who exhibit these early symptoms have a higher risk of ultimately being diagnosed as dyslexic.

For pre-school age children, some of these symptoms are:

• Delays in speech
• Learns new words slowly
• Has difficulty rhyming words, as in nursery rhymes
• Reduced letter knowledge
• Letter reversal, ex: e b f p (normal)
