Landau Kleffner Syndrome

What is Landau-Kleffner syndrome?

Landau-Kleffner Syndrome (LKS) is a rare neurological disorder that causes a loss of language skills (aphasia). It can happen either suddenly or gradually. LKS usually occurs in children between ages 3 and 7 and can affect the child’s ability to speak, understand language or both. Many children with LKS also have seizures.

LKS is often difficult to diagnose because it can resemble other conditions, such as autism and pervasive developmental disorder.
