Ohtahara syndrome (OS), also known as Early Infantile Epileptic Encephalopathy with Burst-Suppression (EIEE), is a progressive epileptic encephalopathy. The syndrome is outwardly characterized by tonic spasms and partial seizures, and receives its more elaborate name from the pattern of burst activity on an electroencephalogram (EEG).

Definition. Ohtahara syndrome is an uncommon type of epilepsy characterized by hard to control seizures and developmental delays. The disorder affects infants, usually within the first three months of life (most often within the first 10 days) in the form of epileptic seizures.
The EEG is the most important test in making a diagnosis of Ohtahara syndrome. The EEG is very abnormal with a burst suppression pattern (high amplitude spikes followed by little brain activity or flattening of the brain waves).
Early Infantile Epileptic Encephalopathy (EIEE) is a neurological disorder characterized by seizures. The disorder affects newborns, usually within the first three months of life in the form of epileptic seizures.
EIEE can be caused by mutations in the ARX gene. This is a regulatory gene involved in brain development, and it is thought that a reduction in the protein produced by the ARX gene is the main effect of the ARX mutation. Changes in genes not located on the X chromosome can also cause infantile spasms in rare cases.
This is a very rare epilepsy syndrome. Seizures start before 3 months of age. Many babies have an underlying structural brain abnormality or a metabolic (biochemical) disorder.
There are several treatment options used to manage Ohtahara syndrome, but there is not a cure. These treatments can help reduce the frequency and severity of the seizures, but they are not effective in managing developmental problems.
Developmental and epileptic encephalopathy 1 (DEE1) is a seizure disorder characterized by a type of seizure known as infantile spasms. The spasms usually appear before the age of 1.
Spasms are typically shorter than what most people think of when they think of seizures — namely, a tonic-clonic (grand mal) seizure. Infantile spasms last around one to two seconds in a series; whereas other types of seizures can last from 30 seconds to two minutes.
The most common causes of epileptic encephalopathy in infancy are structural abnormalities, either congenital (such as malformations of cortical development) or acquired (such as hypoxic-ischemic insults).
The diagnosis of these epileptic encephalopathies begins with an EEG which should include both the sleep and wake states. A magnetic resonance imaging of the brain must be obtained to look for structural defects.
Hormonal and immune therapies are at the forefront of treatment in many cases, with traditional antiepileptic drugs and surgery (when an identifiable lesion is present) playing a limited role. However, gold standard evidence for treatment of epileptic encephalopathies remains limited.
Early infantile epileptic encephalopathy is genetically heterogeneous; in addition to STXBP1 and ARX, we will highlight other genes with their associated clinical presentation (e.g. cyclin-dependent kinase-like 5 (CDKL5) and solute carrier family 25 member 22 (SLC25A22)) in other sections of this guide.
The ICD code G404 is used to code Ohtahara syndrome.

The syndrome is outwardly characterized by tonic spasms and partial seizures, and receives its more elaborate name from the pattern ...
G40.40. Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail. ICD Code G40.40 is a non-billable code.
ICD Code G40.40 is a non-billable code. To code a diagnosis of this type, you must use one of the two child codes of G40.40 that describes the diagnosis 'oth generalized epilepsy, not intractable' in more detail. G40.40 Other generalized epilepsy and epileptic syndromes, not intractable.
Ohtahara syndrome is rare and the earliest-appearing age-related epileptic encephalopathy, with seizure onset occurring within the first three months of life, and often in the first ten days. Many, but not all, cases of OS evolve into other seizure disorders, namely West syndrome and Lennox-Gastaut syndrome.
It can be associated with mutations in ARX, CDKL5, SLC25A22, STXBP1, SPTAN1, KCNQ2, ARHGEF9, PCDH19, PNKP, SCN2A, PLCB1, SCN8A, ST3GAL3, TBC1D24, BRAT1 and likely others .

Onset of EIEE occurs within the first 3 months of life but some present within the first few weeks after birth. Neonates have poor suckling reflexes, hypotonia and manifest with generalized and symmetrical tonic spasms that can appear in clusters or singly and can last for up to 10 seconds.
EIEE may be the result of different etiologies. Many cases have been associated with structural brain abnormalities.
Diagnosis is based on clinical and electroencephalographic findings. The characteristic electroencephalogram (EEG) displays a suppression burst pattern (which appears with the onset of spasms) that is comprised of bursts of high amplitude spikes and polyspikes that alternate with periods of low voltage basic rhythm (suppression).
Differential diagnoses include other epileptic encephalopathies such as early myoclonic encephalopathy, West syndrome (see these terms) and other early onset epileptic encephalopathies.
Prenatal diagnosis is possible in families with a known genetic etiology.
Autosomal recessive inheritance has been reported, but most cases of EIEE are sporadic ( de novo mutations). Genetic counseling is therefore very valuable to inform parents that their risk of having further children with EIEE is low.
