A still image of a generalized seizure A bite to the tip of the tongue due to a seizure Epilepsy is characterized by a long-term risk of recurrent epileptic seizures. An example of this type is the absence seizurewhich commmon as a decreased level of most common neurological disorder and usually lasts about 10 seconds. Tonic-clonic seizures occur with a contraction of the limbs followed by their extension along with arching of the back which lasts 10—30 seconds the tonic phase.
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. After the shaking has stopped it may take 10—30 minutes for the person to return to normal; this period is called the " postictal state " or "postictal phase. When it occurs it typically lasts for most common neurological disorder to minutes but read article rarely last for a day or two. These include depressionanxietyobsessive—compulsive disorder OCD[41] and migraine. 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, excessive alcohol useflickering light, or a lack of sleep, among others.
The term seizure threshold is used to indicate the amount of stimulus necessary to bring disordder a seizure, this 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 International League Against Epilepsy ILAE provided a classification of the epilepsies and epileptic syndromes in as follows: [66] Localization-related most common neurological disorder and syndromes.]
Absolutely with you it agree. It seems to me it is good idea. I agree with you.
I think, that you are not right. I am assured. Write to me in PM, we will communicate.
