How do you diagnose Landau-Kleffner syndrome?

Landau-Kleffner syndrome is commonly diagnosed using an electroencephalogram (EEG). This is a scan that shows the brain’s electrical waves. Other diagnostic tests may be used.

Is Landau-Kleffner syndrome autism?

Landau-Kleffner Syndrome It is twice as common in males than females and is often diagnosed in conjunction with autism. Initially, these individuals have a healthy, problem-free development with normal speech and vocabulary.

Can Landau-Kleffner syndrome be cured?

What is the outlook for people with Landau-Kleffner syndrome? The outlook for recovering language is poor when LKS starts early in life or lasts for a long time without successful treatment. Seizures and EEG abnormalities go away in most cases.

How common is LKS?

LKS is very rare. It is most common in children between the ages of 3 and 7 years old. LKS affects twice as many boys as girls. The cause of LKS is unknown.

What is Landau Kleffner?

Definition. Landau-Kleffner syndrome (LKS) is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electro-encephalogram (EEG).

Is Landau Kleffner syndrome a disability?

Some children with Landau-Kleffner syndrome may develop behavioral problems including hyperactivity, attention deficits, temper outbursts, impulsivity, and/or withdrawn behaviors. Some children with Landau Kleffner syndrome may also have intellectual disability .

Is Landau-Kleffner syndrome a disability?

When was Landau Kleffner discovered?

It is named after William Landau and Frank Kleffner, who characterized it in 1957 with a diagnosis of six children.

What is Landau-Kleffner?

When was Landau-Kleffner discovered?

How is Landau Kleffner syndrome ( LKS ) diagnosed?

Landau-Kleffner syndrome (LKS) is diagnosed based on clinical features and the results of an electroencephalogram (EEG). An EEG is a recording of the electrical activity of the brain, and this can be completed when a child is asleep or awake. Children with LKS have abnormal electrical brain activity on both the left and right side of the brain.

When does aphasia develop in Landau Kleffner syndrome?

Landau-Kleffner syndrome (LKS) is characterized by the sudden or gradual development of aphasia (the inability to understand or express language). Children affected with LKS have developed normally until signs and symptoms begin between the ages of 2 and 8.

When did Landau and Kleffner report their findings?

The correlation between paroxysmal EEG discharges and language deterioration was first suggested by Landau and Kleffner (1957), who reported five children with acquired aphasia associated with a convulsive disorder 1.

How are EEGs used to diagnose LKS?

An EEG is a recording of the electrical activity of the brain, and this can be completed when a child is asleep or awake. Children with LKS have abnormal electrical brain activity on both the left and right side of the brain. [1] Brain MRI may be used to confirm that there is not another underlying cause of the symptoms.
