What is Ohtahara Syndrome?

Ohtahara syndrome, or Early Infantile Developmental and Epileptic Encephalopathy (EIDEE) is a rare epilepsy disorder, characterized by drug-resistant seizures and developmental delay, with onset usually within the first three months of life, but often within the first ten days. Ohtahara Syndrome occurs in 10 in every 100,000 live births.

What Causes Ohtahara Syndrome?

There are several known causes of Ohtahara syndrome, including structural abnormalities of the brain, metabolic disorders, or gene mutations. However, some cases have no known cause. Girls and boys are equally affected by Ohtahara syndrome.

What Challenges Will Children with Ohtahara Syndrome Face?

Tonic seizures (stiffening of muscles, upward eye gaze, pupil dilation, altered breathing) are most common in infants with Ohtahara syndrome, although they may also experience focal seizures (involving only one part of the brain), and rarely, myoclonic seizures (sudden jerks or twitches). It is not uncommon for children with Ohtahara syndrome to present with more than one type of seizure.

Other symptoms include:

What Are Some Treatment Options for Ohtahara Syndrome?

There is currently no cure for Ohtahara syndrome, although epilepsy surgeries are often considered for suitable candidates, with the aim to improve seizure control. Early intervention should begin as soon as possible following a diagnosis of Ohtahara syndrome, as it can support development in areas of gross motor, fine motor, communication, cognition, and social-emotional skills. Physiotherapy may focus on improving mobility, muscular strength, coordination, and endurance. Occupational therapy may target improving upper limb strength and functional use, and posture to support activities of daily living, such as dressing. Speech and language pathology may support increasing speech intelligibility (i.e., ability to be understood) as well as developing expressive and receptive language.
