Cryptogenic generalized epilepsy	Is a	Tonic-clonic epilepsy	false	Inferred relationship	Some
Cryptogenic generalized epilepsy	Is a	A type of epilepsy with only generalised onset epileptic seizures.	false	Inferred relationship	Some
Cryptogenic generalized epilepsy	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. This definition is harmonious with the Federation of Association of Anatomist Second Edition (2019) Part V Terminologia Anatomica.	false	Inferred relationship	Some	1

Lennox-Gastaut syndrome	Is a	False	Cryptogenic generalized epilepsy	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	Cryptogenic generalized epilepsy	Inferred relationship	Some
Epilepsy with myoclonic absence presents with daily myoclonic absence seizures between 1 to 12 years of age. Other generalised seizure types which may be seen in this syndrome include generalised tonic-clonic seizures, clonic, atonic and typical absence seizures. Developmental impairment may be present at onset of epilepsy and may become more evident with age. The electroencephalogram shows regular three Hz generalised spike-and-wave pattern time-locked with myoclonic jerks, with a normal background.	Is a	False	Cryptogenic generalized epilepsy	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	Cryptogenic generalized epilepsy	Inferred relationship	Some

Myoclonic seizure	Is a	False	Cryptogenic generalized epilepsy	Inferred relationship	Some
Refractory myoclonic epilepsy	Is a	False	Cryptogenic generalized epilepsy	Inferred relationship	Some
Cryptogenic late-onset epileptic spasms is a rare epilepsy syndrome characterized by late-onset (after 1 year old) epileptic spasms that occur in clusters, associated with tonic seizures, atypical absences and cognitive deterioration. Language difficulties and behavior problems are frequently present. EEG is characterized by a temporal, or temporofrontal, slow wave or spike focus combined with synchronous spike-waves and no hypsarrhythmia or background activity.	Is a	False	Cryptogenic generalized epilepsy	Inferred relationship	Some
