Complex partial status epilepticus CPSE is one of the non-convulsive forms of status epilepticusa rare form of epilepsy defined by its recurrent nature.

Epilepsy [1] [2] [3] is a disease manifested by recurrent paroxysmal attacks of transient cerebral dysfunction with pathological electrical activity of nervous tissue caused by excessive discharges of cerebral neurons. The diagnosis of epilepsy is made on the basis of repeated unprovoked seizures. It is the primary pathology of brain tissue at the cellular level - idiopathic epilepsy. They typically have a positive family history, a negative personal history, normal psychomotor development, a normal neurological finding, a normal intellect, and normal EEG activity between seizures [3]. They are caused by a pathological formation in the brain tissue that changes its electrical properties and manifests itself as epilepsy only as a symptom. These are congenital malformations of the brain cortical dysplasia , perinatal damage, mesiotemporal sclerosis, strokes, tumors, inflammation, injuries, postoperative scars, vascular anomalies, degenerative diseases and more. They have a rather negative family history, a positive personal history, delayed psychomotor development, decreased intellect, slow basic EEG activity, signs of a brain lesion in imaging methods [3].

Occipital epilepsy is characterized by occipital seizures originating from an epileptic focus within the occipital lobes. In a population study of newly diagnosed epilepsy, occipital seizures were diagnosed in 1. Seizures commonly spread from the occipital region to more anterior regions of the brain. Sensory and motor symptoms come from the lateral supracalcarine area. Complex posturing is secondary to medial supracalcarine spread. The pathogenesis of occipital seizures is dependent on the underlying etiology. Etiologies can include:. Symptomatic occipital epilepsies secondary to structural or other identifiable lesions:. Situation-related occipital seizures or conditions with occipital epileptic seizures that are traditionally not diagnosed as a form of epilepsy:. Diagnosis relies on a detailed history and EEG findings. Neuroimaging studies may be done to rule out other etiology but are not necessary for diagnosis. A history of visual hallucinations, and external manifestations listed under symptoms should be investigated. In children, additional critical signs include vomiting, pallor, and eye deviation. Symptoms are typically visual and oculomotor and may be classified as subjective, objective, or both. Visual subjective symptoms are characterized by transient visual symptoms that may be positive flashes, phosphenes or negative amaurosis, hemianopia, scotoma.

SE most commonly manifests as generalised tonic-clonic seizures, but there are other types of status epilepticus, including non-convulsive status epilepticus. Seizures can be permanent, especially if they are associated with a focal CNS lesion. Simple partial seizures can be accompanied by various subjective bodily or sensory sensations e. Prolonged simple partial seizures often motor and clonic are often called epilepsia partialis continua. Simple partial seizures are not always associated with diffuse CNS damage unless they progress to complex partial SE or are associated with secondary generalisation. Non-convulsive SE is characterised by continuous epileptogenic activity on the EEG without a motor correlate. Cramps for which we are able to identify the cause are called symptomatic, in the case of an unclear cause we choose the term idiopathic or cryptogenic.

A complex partial seizure is a type of seizure that arises in one lobe of the brain, rather than the whole brain. There are numerous possible symptoms. Complex partial seizures are now more commonly referred to as focal onset impaired awareness seizures or focal impaired awareness seizures. Anybody can have a complex partial seizure, although people who have experienced head injuries, strokes , or tumors in the brain are more at risk. Seizures are often preceded by an aura, known as a simple partial seizure.

If the pathological activity affects only a small part of the cortex and there is no impairment of consciousness, the seizure is called a simple partial. They have a rather negative family history, a positive personal history, delayed psychomotor development, decreased intellect, slow basic EEG activity, signs of a brain lesion in imaging methods [3]. In people 65 or older, cerebrovascular disease and degenerative disorders are the most commonly known etiologies. Federal government websites often end in. Korean J Physiol Pharmacol. Epilepsia partialis continua Complex partial status epilepticus. Wilson, J. It cannot be used to rule out the diagnosis and may be falsely positive in those without the disease. There is no clear evidence that antiepileptic drugs are effective or not effective at preventing seizures following a craniotomy , [71] following subdural hematoma , [72] after a stroke , [73] [74] or after subarachnoid haemorrhage , [75] for both people who have had a previous seizure, and those who have not.

Toggle limited content width. Partial seizures can spread and, when all areas of the cortex are affected, are then considered to be secondarily generalized eg, Jackson's tonic-clonic seizures generalizing proximally from a focal attack on the periphery. There may also be loss of memory amnesia surrounding the seizure event. Unknown onset Motor onset tonic-clonic epileptic spasm Non-motor onset behavior arrest Unclassified.

Versive eye movements typically contralateral or epileptic nystagmus may be seen. Simple partial seizures are a very subjective experience, and the symptoms vary greatly between people.
