People who have epilepsy suffer from an abnormality of their brain that causes them to have seizures — generalized convulsions of their body (muscle spasms) or more subtle mental or physical behavioral disturbances lasting from seconds to minutes and typically recurring at varying intervals.[1] Some types of seizures manifest as strange sensations or emotional states, and others, unconsciousness.

In technical terms, the U.S. National Library of Medicine, citing Adams et al.,[2] defines epilepsy as "a disorder characterized by recurrent episodes of paroxysmal [sudden, intense] brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge [discharge of electrical activity by nerve cells]. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology [cause] (e.g., post-traumatic [after an injury]), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal [time related] patterns."[3]

Historical notes relating to epilepsy

The ancient Greeks recognized epilepsy, calling it the Sacred Disease, as they regarded it as inflicted by the gods. But Hippocrates of Cos (460 BCE - ?360 BCE), who recognized that diseases had natural causes, recognized epilepsy as a natural disorder of the brain:[4]

It is thus with regard to the disease called Sacred: it appears to me to be nowise more divine nor more sacred than other diseases, but has a natural cause from the originates like other affections....this disease seems to me to be no more divine than others; but it has its nature such as other diseases have, and a cause whence it originates, and its nature and cause are divine only just as much as all others are, and it is curable no less than the others, unless when, the from [the length] of time, it is confirmed, and has became stronger than the remedies applied....the brain is the cause of this affection, as it is of other very great diseases, and in what manner and from what cause it is formed, I will now plainly declare….

Classification

Benign neonatal epilepsy

Partial epilepsy

Febrile seizures

Generalized epilepsy

Landau-Kleffner syndrome

Myoclonic epilepsy

Post-traumatic epilepsy

Reflex epilepsy

Status epilepticus

For more information, see: Status epilepticus.


Pathophysiology

The overexcitability of the brain in epilepsy predominantly involves the NMDA receptor, a ionic receptor of glutamate. The NMDA receptor uses magnesium to regulate the entry of calcium in neurons and prevent epileptiform activity. Epileptic patients have lower than normal ionic magnesium, although the more common laboratory test, total magnesium, remains normal.[5]

Treatment

Many medications are available that vary in efficacy, drug toxicity, and costs.[6]Due to the narrow therapeutic window of these medications, generic substitution should be done carefully according to a clinical practice guideline.[7]

Monitoring of drug levels may help.[8]

Levetiracetam was approved in the United States of America November 30, 1999[9] and the European Union September, 2000[10] and so was not included in the SANAD randomized controlled trial which started randomizing patients on Dec 1, 1999.[11][12][13]

Generalised epilepsy

For idiopathic generalised epilepsy or difficult to classify epilepsy, the SANAD randomized controlled trial compared valproate, lamotrigine, or topiramate and concluded:[11][12]

Partial epilepsy

For partial epilepsy, the SANAD randomized controlled trial compared carbamazepine, gabapentin, lamotrigine, oxcarbazepine, or topiramate and concluded:[13]

A separate randomized controlled trial compared levetiracetam to carbamazepine while drug toxicity is lower for levetiracetam than carbamazepine.[14]

Lamotrigine and levetiracetam have not been compared as of June, 2008.

Prognosis

After a first seizure, the likelihood of a second seizure within three years is 29%[15][16] to 78%[17].
