A seizure happens when electrical activity in the brain surges suddenly. Epilepsia partialis continua EPC is a condition that occurs when seizures happen every few seconds or minutes. This can continue for days, weeks or even years.

Epilepsia partialis continua is a rare  type of brain disorder in which a patient experiences recurrent motor epileptic seizures that are focal hands and face , and recur every few seconds or minutes for extended periods days to years. During these seizures, there is repetitive focal myoclonus or Jacksonian march. After a seizure has subsided, Todd's phenomenon may be observed, which includes transient unilateral weakness. There are numerous causes for this kind of seizure and they differ depending somewhat on the age at which the seizures begin.
Epilepsy most often occurs at the extremes of life — in childhood or in very old age — but can develop at any time throughout one's life. Although these seizures are usually due to large, acute brain lesions resulting from strokes in adults and focal cortical inflammatory processes in children Rasmussen's encephalitis , possibly caused by chronic viral infections, edema, or autoimmune processes.
They are very medication and therapy-resistant, and the primary therapeutic goal is to stop secondary generalization. There are also many other reasons why these seizures occur. For example, they could be due to genetics, infections, or problems with brain development. Commonly the cause is unknown. Genetic background determines such features as height, eye color, and potential to develop certain diseases like diabetes, but it also determines all the chemicals and structures that make up the brain, therefore playing a role in Epilepsia partialis continua.
The chemicals and structures that make up the brain have similarities across different people, but they vary in certain enzymes and receptors. These variations are not usually enough to cause a problem, but occasionally they do. For example, if a person has a mutation in a gene that creates the sodium channel a part of the neuron required for firing it makes it easier for neuronal firing to get out of control. An infection of the brain encephalitis can also be a contributing factor.
Although this sort of infection is uncommon it can be due to a virus, bacterium, or very rarely fungus. If a seizure happens during the infection itself, the person most likely doesn't have epilepsy but has "symptomatic seizures" or seizures occurring because of a known injury to the brain. Once the infection is stopped the seizures will stop.
Another more common infection is "meningitis", infection of the membranes surrounding the brain. Since this infection does not directly involve the brain it might not appear as a possible cause of epilepsy, but has been shown that meningitis can cause epilepsy, which would give rise to the possibility of developing epilepsy partialis continua. These infections are most likely to result in epilepsy when they occur at an early age. Problems with brain development can also be a factor.
The brain undergoes a complicated process during development in which neurons are born and must travel to the surface of the brain. Here they wind up carefully placed in six distinct layers of the cerebral cortex.
Throughout the brain, the placement of these neurons is normally quite precise. If this system doesn't work exactly right, neurons can develop outside their appropriate areas.
If this happens then the firing or circuitry of the brain is not right, and an abnormal, epileptic circuit can result. Identification of the underlying cause plays an important role in treatment. If seizures do continue, various anticonvulsant medication regimens that can be tolerated by the patient can be tested and if need be, administered, either orally, or in emergency conditions such as status epilepticus after tonic-clonic grand mal seizures, intravenously. If stroke or other similar, transient disorders occur cerebrovascular accident, or transient ischemic attack, TIA , then neurological imaging of the affected lobes or hemispheres of the brain can be performed CT, MRI, PET, etc.

Epilepsia partialis continua
Epilepsia partialis contina EPC in a narrow definition is a variant of simple focal motor status epilepticus in which frequent repetitive muscle jerks, usually arrhythmic, continue over prolonged periods of time. In a broader definition used in this review it also includes non-motor manifestations otherwise known as aura continua. EPC may occur as a single episode, repetitive episodes, it may be chronic progressive or non-progressive. It appears as an unusual manifestation of epilepsy in which more typical paroxysmal events are partly or entirely replaced by the sustained repetition of seizure fragments in rapid succession. The minimum duration is defined as one hour but EPC may continue for up to many years. There are multiple possible etiologies which can be local or systemic, including two disease entities, Rasmussen encephalitis and Russian tick-borne spring-summer encephalitis.
Epilepsia partialis continua of Kozhevnikov
This article includes discussion of epilepsia partialis continua of Kozhevnikov, epilepsia partialis continua Bancaud type I, focal motor epilepsia partialis continua, focal motor status epilepticus, Kozhevnikov syndrome type 1, and partial motor status epilepticus. The foregoing terms may include synonyms, similar disorders, variations in usage, and abbreviations. Epilepsia partialis continua is a rare form of simple focal motor status epilepticus of mainly cerebral cortical origin. It manifests with repetitive, regular, or irregular localized clonic muscle twitching, lasting for a few milliseconds and repeated at least every 10 seconds for hours, days, or months without impairment of consciousness. Onset occurs at any age, but starts before 16 years of age in a third of cases.
