Landau-Kleffner Syndrome (LKS)

What is Landau-Kleffner Syndrome (LKS)?

Landau-Kleffner Syndrome (LKS) is a rare childhood disease in which children experience a variety of seizure types, and gradually lose the understanding of language and eventually speech production (aphasia). Symptoms usually begin between age 3 and 8 and are more common in boys than girls. These children display EEG abnormalities, usually in the speech areas over the parietal and temporal regions, and more prominently during sleep.

How is Landau-Kleffner syndrome treated?

Certain anticonvulsant medications and steroids can decrease seizures and improve aphasia, but others can worsen language function, so patients should be closely monitored by their doctor.
