Disorder of written expression is a childhood condition which involves poor writing skills.

Although no body-wide (systemic) studies have been conducted to determine how common this disorder is, it is thought to be about as common as learning and reading disorders.

This disorder appears by itself or along with other learning disabilities such as:

• Reading disorder
• Expressive language disorder
• Mathematics disorder
• Developmental coordination disorder

• Errors in grammar and punctuation
• Poor handwriting
• Poor spelling

Other causes of learning disabilities must be ruled out before the diagnosis can be confirmed.

Remedial education is the best approach to this type of disorder.

The degree of recovery depends on the severity of the disorder. Marked improvement is often seen after treatment.

• Learning problems
• Low self-esteem
• Problems with socializing

Parents who are concerned about their child's language ability should have the child tested by educational professionals.

Learning disorders often run in families. Affected or potentially affected families should make every effort to recognize problems early. Intervention can begin as early as preschool or kindergarten.
