Benign myoclonic epilepsy in infancy (BMEI), first described by Dravet and Bureau in 1981, is a rare epilepsy syndrome. 1 It is classified among the idiopathic generalized epilepsies and typically begins by the age of 3 years. 2 BMEI is characterized by brief myoclonic seizures without other seizure types in developmentally normal children.

Myoclonic Seizures. Myoclonic seizures tend to recur for years. They are more common during childhood and young adulthood, and often improving during one's 

Seizures begin from 4 months to 3 years of age, but most commonly between 1 and 2 years of age. Overview. Myoclonic epilepsy in infancy is a rare self-limited idiopathic generalized epilepsy that typically appears between 6 months and 2 years of age. It is characterized by the occurrence of myoclonic seizures as the unique type of seizure (expect simple febrile seizure) occurring in normal infants, either spontaneously or induced by unexpected acoustic or tactile stimuli (reflex variant). Juvenile myoclonic epilepsy (JME) is a type of epilepsy that causes myoclonic seizures (muscle jerks). A seizure is an episode of abnormal brain activity.

Purpose: Myoclonic epilepsy in infancy (MEI) is characterized by brief generalized myoclonic seizures associated with generalized spike-wave paroxysms without other seizure types occurring in the first 3 years of life in developmentally normal children. Myoclonic seizures may be activated by photic stimulation in some patients, others may have myoclonic seizures that are induced by sudden noise or touch. Cognitive, behavioral and motor difficulties may exist. Seizures are self-limiting, ceasing within 6 months to 5 years from onset. Generalized tonic-clonic seizures may be seen in later life. We evaluated 16 patients with myoclonic epilepsy, , cardiac calcifications and/or fibrosis (13–15), and hydrops fetalis or the collodion baby phenotype (16, 17).

Sometimes myoclonic seizures are not strong enough to cause visible movement, but the child feels a shock-like feeling in their muscles.

In some syndromes, such as juvenile myoclonic epilepsy, myoclonic seizures happen in the morning just after the child wakes up.

Juvenile myoclonic epilepsy is an epilepsy syndrome characterized by myoclonic jerks (quick jerks of the arms or legs), generalized tonic-clonic seizures (GTCSs), and sometimes, absence seizures. The seizures of juvenile myoclonic epilepsy often occur when people first awaken in the morning. Benign myoclonic epilepsy in infancy is a rare syndrome in which brief bouts of generalized myoclonus occur during the first or second year of life.

gressive myoclonic epilepsy (PME) syndromes are the most severe of the myoclonic epilepsies. Diagnosis of PME syn-dromes on clinical grounds can be difficult, but advances in genetic testing have made diagnoses more accurate. Some other benign myoclonic epilepsy syndromes also have identi-fied gene markers, which can aid in diagnosis. To accurately

The International League Against Epilepsy (ILAE) Diagnostic Manual's goal is to assist clinicians who look after people with epilepsy to diagnose the epilepsy syndrome and (if possible) the etiology of the epilepsy. Arriving at the correct epilepsy syndrome and/or etiology allows better decision-making about treatment and improves patient care. ETIOLOGY. Myoclonic epilepsies are predominantly genetic in origin. In terms of classification, they may be grouped as genetic epilepsies (e.g., benign myoclonic epilepsy in infancy [BMEI]), epileptic encephalopathies (e.g., Dravet syndrome), or progressive myoclonic epilepsies (e.g., Unverricht–Lundborg disease).
