(HealthDay News) -- Dyslexia is a learning disability that affects the way a child reads and writes.

The Nemours Foundation says an inability to perform the following functions are common warning signs of dyslexia among preschool and elementary school children:

• Learning to read and speak.
• Rhyming.
• Understanding and identifying things like colors, shapes, numbers, letters and days of the week.
• Reading and writing one's own name.
• Correlating letters and sounds.
• Mixing up letter sequences and reading incorrectly, such as reading "top" as "pot."
• Poor handwriting and difficulty with other fine-motor skills.
