Publications Definition The epilepsies are a spectrum of brain disorders ranging from severe, life-threatening and disabling, to ones that are much more benign. In epilepsy, the normal pattern of neuronal activity becomes disturbed, causing strange sensations, emotions, and behavior or sometimes convulsions, muscle spasms, and loss of consciousness. The epilepsies have many possible causes and there are several types of seizures.

An example of this type is the absence seizurewhich presents as a decreased level of consciousness and usually lasts about 10 seconds.
A cry may be heard due to contraction of the chest muscles, followed by a shaking of the limbs in unison clonic phase. Tonic seizures produce constant contractions of the muscles.
A person often turns blue as breathing is stopped. In clonic seizures there is shaking of the limbs in unison. When it occurs it typically lasts for seconds to minutes but may rarely last for a day or two.
These include depressionanxietyobsessive—compulsive disorder OCD and migraine. Causes of seizures Epilepsy can have both genetic and acquired causes, with interaction of these factors in many cases. There appears to be a specific syndrome which includes coeliac disease, epilepsy and calcifications in the brain.
Factors within the neuron include the type, number and distribution of ion channelschanges to receptors and changes of gene expression.
However, it is unknown under which circumstances the brain shifts into the activity of a seizure with its excessive synchronization. Seizures are often brought on by factors such as stress, alcohol abuse, flickering light, or a lack of sleep, among others.
The term seizure threshold is used to indicate the amount of stimulus necessary to bring about a seizure. Seizure threshold is lowered in epilepsy. The diagnosis of epilepsy is typically made based on observation of the seizure onset and the underlying cause.
The definition of epilepsy requires the occurrence of at least one epileptic seizure.
In the definition, epilepsy is now called a disease, rather than a disorder. This was a decision of the executive committee of the ILAE, taken because the word "disorder," while perhaps having less stigma than does "disease," also does not express the degree of seriousness that epilepsy deserves.
In particular, it aims to clarify when an "enduring predisposition" according to the conceptual definition is present. Researchers, statistically-minded epidemiologists, and other specialized groups may choose to use the older definition or a definition of their own devising.
The ILAE considers doing so is perfectly allowable, so long as it is clear what definition is being used. When a person is admitted to hospital after an epileptic seizure the diagnostic workup results preferably in the seizure itself being classified e.The UCLA Seizure Disorder Center, established in , is a world leader in epilepsy investigations.
Clinical and basic neuroscientists carry out research at all levels of investigation, ranging from genetics and cellular physiology to public health and outreach to developing countries. Local.
The Epilepsy Phenome/Genome Project is a large-scale, national, multi-institutional, collaborative research project aimed at advancing our understanding of the genetic basis of the most common forms of idiopathic and cryptogenic epilepsies and a subset of symptomatic epilepsy; i.e., epilepsies that are likely related to genetic predispositions.
Aug 08, · Research on the underlying causes of the epilepsies, including identification of genes for some forms of epilepsy, has led to a greatly improved understanding of these disorders that may lead to more effective treatments or even to new ways of preventing epilepsy in the future.
Epilepsy is a disorder of recurrent unprovoked seizures. More than half of seizures can be controlled by anti‐epileptic medications. For the remaining patients, they . Many parents, family & caregivers have similar concerns regarding the care they give to people with epilepsy.
