==Overview==
A '''complex partial seizure''' is an [[epilepsy|epileptic]] attack that involves a greater degree of [[impairment]] or alteration of [[consciousness]]/[[awareness]] and memory than a [[simple partial seizure]]. 

==Presentation==

Complex partial seizures are often precipitated by an [[Aura (symptom)|aura]], which is itself a [[simple partial seizure]]. This may begin with a feeling of ''[[déjà vu]]'' or ''[[jamais vu]]''. The person may then have feelings of fear, euphoria or depression, and possibly [[depersonalization]]. They may experience visual disturbances, such as [[tunnel vision]] or a change in the size of objects. Once consciousness is impaired, the person may display “automatisms” such as lip smacking, chewing, swallowing, and undressing oneself. There may also be loss of memory ([[amnesia]]) surrounding the seizure event. As the person may still be able to perform routine tasks such as walking or shopping, witnesses may not recognize anything is wrong.

Although the origins of complex partial [[seizure]] vary, they usually originate in the [[temporal lobe]]s of the brain, particularly on the [[hippocampal sclerosis|hippocampus]]. It is often caused by mesia lesions in the brain, which are essentially a ridge of [[scar tissue|scar-like tissue]]. Like more generalized [[epilepsy]], [[complex partial seizure]]s are caused by a misfiring of a synapse in the brain, causing which causes a “storm like” reaction with bursts of electricity that can result in changes in personality and physicality. Often, the abnormal activity spreads to the rest of the brain, causing a [[secondary generalized seizure]].

A partial (focal) [[seizure]] may occur at any age, as a single episode or as a repeated, chronic [[seizure]] disorder ([[epilepsy]]). They are seen less frequently in children than in adults, but still account for about 45% of [[pediatric seizure disorders]].

== Creativity & Epilepsy ==

[[Complex partial seizure]]s experienced in some people may be conducive to enhanced creativity. In 2002, researchers at the Gulhane Military Medical Academy in Turkey evaluated thirty men with epilepsy and thirty-six men without. The men were instructed to use fragmented parts of a drawing to create a picture of their own. Those with complex partial seizures scored higher than their counterparts.

==Complex partial seizures and religious hallucinations==

There are several religious figures suspected of having complex partial seizures. Ezekiel could have suffered from complex seizures [http://www.newscientist.com/channel/health/mental-health/dn1565.html]. Though her supporters disagree, the founder of the Seventh-day Adventist Church, Ellen G. White's visions of God may have been caused by partial seizures. She had previously lost consciousness from a head injury [http://www.ellenwhite.org/seizures.htm]. Her brain injury was significant enough to prevent her return to school.
