(HealthDay News) -- Dyslexia, also called developmental reading disorder, is a condition in which the brain doesn't correctly process certain images, such as numbers and letters, says the U.S. National Library of Medicine (NLM). It's caused by a problem with the region of the brain that processes language and it hampers a child's ability to read.

Symptoms of dyslexia include problems understanding simple sentences and difficulty rhyming and recognizing words. Dyslexia also makes it difficult to associate written words with the corresponding sounds. As a result, children with dyslexia are likely to be slow readers.

For children struggling with dyslexia, the NLM offers these tips:

• Children with dyslexia may need extra schooling and a private tutor to improve their reading.
• It's important to use positive reinforcement when working with children with the learning disorder.
• Counseling may help with issues of self-esteem.
