People who have epilepsy suffer from a 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 brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns."[3]
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 discovered that diseases had natural causes, recognized it 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 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
Treatment
A randomized controlled trial concluded:[5][6]
- For idiopathic generalised epilepsy or difficult to classify epilepsy, "valproate remains the clinically most effective drug, although topiramate may be a cost-effective alternative for some patients".
- For partial seizures, "lamotrigine may be a clinical and cost-effective alternative to the existing standard drug treatment, carbamazepine"
