Landau-Kleffner syndrome is a rare language disorder. It frequently occurs in normally developing children, usually between five and seven years of age, and is characterized by the gradual or sudden loss of the ability to use or comprehend spoken language.
The following are the most common indicators of Landau-Kleffner syndrome. However, each individual may experience symptoms differently.
Early signs may be referred to as auditory agnosia, which includes the child:
Suddenly having problems understanding what is said
Appearing to have problems with hearing and deafness may be suspected
Appearing to be autistic or developmentally delayed
Spoken language is eventually affected, which may lead to complete loss of the ability to speak.
Some children develop their own method of communicating, such as using gestures or signs.
Hearing and intelligence usually are confirmed to be normal in children with Landau-Kleffner syndrome.
The symptoms of Landau-Kleffner syndrome may resemble other conditions or medical problems, such as deafness or learning disabilities. Always consult your health care provider for a diagnosis.
Landau-Kleffner syndrome is commonly diagnosed using an electroencephalogram (EEG), a scan that shows the brain's electrical waves, as well as other diagnostic tests.
Specific treatment for Landau-Kleffner syndrome will be determined by your health care provider based on:
Your age, overall health, and medical history
Extent of the disease
Your tolerance for specific medications, procedures, or therapies
Expectations for the course of the disease
Your opinion or preference
Treatment may include medication for seizures and language ability. Speech therapy should be started as early as possible and sign-language instruction may also be suggested.
