How is Landau-Kleffner syndrome 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. Who discovered Landau-Kleffner?
It is named after William Landau and Frank Kleffner, who characterized it in 1957 with a diagnosis of six children.

What causes LKS?

What causes Landau-Kleffner syndrome in a child? Researchers are still learning what causes LKS. It may be caused by changes (mutations) in genes, or by the effects of the environment on certain genes. In some cases, it may be caused by changes in a gene called GRIN2A. What are the characteristics of Williams syndrome?

Newborns with Williams syndrome have characteristic “elfin-like” facial features including an unusually small head (microcephaly), full cheeks, an abnormally broad forehead, puffiness around the eyes and lips, a depressed nasal bridge, broad nose, and/or an unusually wide and prominent open mouth.

What is a Rolandic seizure?

Benign rolandic epilepsy is characterized by twitching, numbness or tingling of the child’s face or tongue, and may interfere with speech and cause drooling. Seizures spread from one area of the brain and become generalized.

What is West syndrome?

West syndrome is a constellation of symptoms characterized by epileptic/infantile spasms, abnormal brain wave patterns called hypsarrhythmia and intellectual disability.

What is acquired aphasia?

Acquired Childhood Aphasia is a language impairment caused by damage to the parts of the brain that control language, typically the left half of the brain. Brain damage in children results most frequently from a traumatic brain injury, but can also result from brain tumors or seizure disorders.

What is a reflex seizure?

Reflex epilepsies are a group of epilepsy syndromes in which a certain trigger or stimulus brings on seizures. 85% of reflex seizures are generalized tonic-clonic seizures. The most common form of reflex epilepsy is photosensitive epilepsy, in which flashing lights trigger seizures.

What is GRIN2A genetic disorder?

GRIN2A related syndrome is a condition that is associated with epilepsy as its most important feature. It occurs when one of the two copies of the GRIN2A gene has lost its normal function. This can be caused by a spelling mistake in the gene or a loss of one copy of the gene, or part of it.

How long can a person live with Williams syndrome?

Some people with Williams syndrome may have a reduced life expectancy due to complications of the disease (such as cardiovascular involvement). No studies specifically exist on life expectancy, although individuals have been reported to live into their 60s.

What is Lennox-Gastaut syndrome and Dravet syndrome?

Lennox-Gastaut Syndrome (LGS) and Dravet Syndrome (DS) are two of the various, rare epileptic disorders classified as epileptic encephalopathies. LGS is estimated to occur in 0.1 to 0.28 people per 100,000 and is believed to account for one to four percent of all cases of childhood epilepsy.

How do you get rid of Hypsarrhythmia?

The two standard treatments for IS are hormone therapy (ACTH or steroids) or a drug called vigabatrin (Sabril®). … If your child doesn’t respond to either hormone treatments or vigabatrin, further treatment options include:

  1. The ketogenic diet.
