Myoclonic seizure	Finding site	The cerebrum is the regional structure of the brain, which is the adult equivalent of the forebrain or prosencephalon. It is constituted by the structural derivatives of the telencephalon and diencephalon including the cerebral hemispheres, epithalamus, thalamus, hypothalamus, lateral ventricles and third ventricle.

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	Myoclonic seizure	Inferred relationship	Some
Myoclonus epilepsy AND ragged red fibers	Is a	False	Myoclonic seizure	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	Myoclonic seizure	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	Myoclonic seizure	Inferred relationship	Some
A rare, genetic, infantile epilepsy syndrome disease characterized by 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	Myoclonic seizure	Inferred relationship	Some
Progressive myoclonic epilepsy	Is a	False	Myoclonic seizure	Inferred relationship	Some
Refractory myoclonic epilepsy	Is a	False	Myoclonic seizure	Inferred relationship	Some
A rare mitochondrial oxidative phosphorylation disorder characterized by myoclonic seizures, ataxia, generalized epilepsy, muscle weakness and ragged red fibers in the muscle biopsy.	Is a	False	Myoclonic seizure	Inferred relationship	Some
