Developmental dysphasia familial

What is developmental dysphasia?

Developmental dysphasia is a language disorder that develops in children. The disorder typically involves difficulties speaking and understanding spoken words. The symptoms cannot be attributed to sensorimotor, intellectual deficits, autism spectrum, or other developmental impairments. Likewise it does not occur as the consequence of an evident brain lesion or as a result of the child's social environment. Familial cases of developmental dyphasia have been described. In these families, the condition is inherited in an autosomal dominant fashion.

Is developmental dysphasia and epilepsy related?

When narrowly defined, developmental dysphasia would not include cases were the cause for the dysphasia is known. In these cases the word "aphasia" rather than "dysphasia" may be chosen, granted however this distinction is often unclear. You may find it helpful to read more about acquired aphasia with convulsive disorder, a condition also known as Landau-Kleffner syndrome. You can find information on this topic on our Web site at the following link:

We encourage you to discus this question further with your child's healthcare provider. They can counsel you regarding the likelihood that your son's seizures played a role in causing his language disorder.
