Epilepsia partialis continua (EPC) is a rare brain disorder where a patient experiences recurrent and, sometimes, unrelenting focal onset. Epilepsia partialis continua (EPC) was first described by Kozhevnikov in a report on four patients with “a special form of cortical epilepsy” to the Russian Society. Summary. Epilepsia partialis continua (EPC) is defined clinically as a syndrome of continuous focal jerking of a body part, usually localized to a distal limb.
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. Recently, a novel approach based on Transcranial Magnetic Stimulation may offer hope for these patients, but awaits further evaluation. Kravljanac et al conducted a cohort study of 51 children with epilepsia partialis continua and recorded neurological consequences in It is resistant to treatment and quite disabling to the patients.
The precise mechanism of initiation and persistence, as also the environmental determinants of this status epilepticus is yet to be elucidated.
We herein report a case of EPC occurring in a young lady which is ongoing presently [Day 93].
It is with deep anguish that we observe this patient every day, though ironically, we find ourselves as disabled as the sufferer. Villupuram Medical College for their dedication and efforts put into the management of this patient and their help towards our academic purpose.

He postulated that the seizures in EPC were due to a form of focal cortical encephalitis and the subsequent inflammation of cerebral motor fibers.
Over the years, several neuroscientists have offered different explanations and interpretations for the possible pathophysiological mechanisms. The causes of EPC are very similar to that of any other form of epilepsy as the basic reason for seizures is abnormal electrical activity in the brain brought on by a myriad of pathologies including architectural damage, cortical dysplasia such as Tuberous Sclerosis, Sturge-Weber syndrome, and linear sebaceous nevus syndrome , drugs, metabolic abnormalities hyponatremia, hypoglycemia, hyperglycemia, hyperuricemia, uremia , neoplastic process oligodendroglioma, meningioma, high grade glioma , autoimmune processes autoimmune encephalitides , or infections.
Rasmussen encephalitis or chronic focal encephalitis CFE , a rare neurological disease seen in children, has shown a strong association with EPC according to the current literature. Hyperexcitability of anterior horn cells was, at the time, believed to be the underlying cause of diseases such as familial progressive myoclonic epilepsy of Unverricht which, like EPC, presented with myoclonic jerks.
Early studies using electroencephalogram EEG and somatosensory evoked potentials SSEPs showed that the waveforms associated with EPC had a positive wave followed by negative shifts with a train of superimposed spikes. Hyperexcitability of the motor cortex and consequent exaggerated responses were also understood to play a part in the disease process.
This phenomenon may be the reason for the localized nature of seizures seen in EPC compared to seizures arising from allocortex of the limbic pathways which is, by design, meant to spread excitation. Some evidence has also shown Jacksonian spread and secondary generalization of seizures, highlighting the complex pathophysiology of the disease.
