A type of epilepsy that presents with myoclonic epileptic seizures, usually between 10 and 24 years of age, in an otherwise normal adolescent or adult. Generalized tonic-clonic seizures occur in greater than 90 percent of individuals and absence seizures occur in a third. Seizures typically occur shortly after waking and when tired. Sleep deprivation is an important provoking factor. Photosensitivity is common. Development and cognition are typically normal. Neurological examination is normal. The electroencephalogram shows 3 to 5.5 Hz generalized spike-wave and polyspike-wave and a normal background.	Is a	False	Myoklonusanfald	Inferred relationship	Some
Myoklonusepilepsi OG forrevne røde fibre	Is a	False	Myoklonusanfald	Inferred relationship	Some
A type of epilepsy that presents with myoclonic-atonic seizures usually between 2 to 6 years of age. Other generalised seizure types which may be seen in this syndrome include atonic, myoclonic, generalised tonic-clonic seizures, tonic and absence seizures. Nonconvulsive status epilepticus is common. Development prior to seizure onset is normal in two thirds of cases. These children typically show developmental stagnation or even regression during the active seizures (stormy) phase, which improves once seizures are controlled. The electroencephalogram shows generalised 2 to 6 Hz spike-wave or polyspike-and-wave abnormalities, with normal background.	Is a	False	Myoklonusanfald	Inferred relationship	Some
Benign adult familial myoclonic epilepsy (BAFME) is an inherited epileptic syndrome characterized by cortical hand tremors, myoclonic jerks and occasional generalized or focal seizures with a non-progressive or very slowly progressive disease course, and no signs of early dementia or cerebellar ataxia.	Is a	False	Myoklonusanfald	Inferred relationship	Some
A rare genetic infantile epilepsy syndrome disease with characteristics of neonatal to infancy onset myoclonic focal seizures occurring in various members of a family, associated in some with mild dysarthria, ataxia and borderline-to-moderate intellectual disability.	Is a	False	Myoklonusanfald	Inferred relationship	Some
Progressive myoclonic epilepsy	Is a	False	Myoklonusanfald	Inferred relationship	Some
Refractory myoclonic epilepsy	Is a	False	Myoklonusanfald	Inferred relationship	Some
A mitochondrial encephalomyopathy with characteristics of myoclonic seizures. Patients usually present during adolescence or early adulthood with myoclonic epilepsy, sometimes with neurosensory deafness, optic atrophy, short stature or peripheral neuropathy. The disease is progressive with worsening of the epilepsy and onset of additional symptoms including ataxia, deafness, muscle weakness, and dementia. Caused by mutations in the mitochondrial DNA.	Is a	False	Myoklonusanfald	Inferred relationship	Some
