If this attack becomes severe, then the patient may lose consciousness and the whole body may start jerking vigorously.
如果这种发作严重，那么病人可能会失去知觉，整个身体可能会开始剧烈的抽搐。
It would then be called as a major epileptic fit.
然后它就会被称为严重的癫痫发作。
Less commonly, these major fits may continue for hours.
不太常见的是，这些大发作可能会持续几个小时。
90% of the times, both types of epileptic fits end within 1-2 minutes.
90%的情况下，两种类型的癫痫发作都会在1-2分钟内结束。
Because of this people sometimes get a wrong impression that it was their intervention that aborted the attack which is not the case.
正因为如此，人们有时会有一种错误的印象，认为是他们的干预导致了袭击的失败，但事实并非如此。
How and how often fits occur?
癫痫是如何发生的，以及多久发生一次？
Epileptic patients tend to have repeated epileptic fits.
癫痫患者往往会反复发作癫痫。
The frequency may vary.
频率可能会有所不同。
One person may have an attack every month, another will have then once in 3 months while a third person may have an attack every week.
一个人可能每个月发作一次，另一个人可能每3个月发作一次，而第三个人可能每周发作一次。
Some people may have an epileptic fit as infrequently as once in 6 months or even once a year.
有些人癫痫发作可能很罕见，6个月一次，甚至一年一次。
Some epileptics may have fits only at night while others may have more attacks early in the morning.
一些癫痫患者可能只在晚上发作，而另一些人可能在清晨发作更多。
This variation is because of different types of underlying epilepsy.
这种变异是由不同类型的潜在癫痫引起的。
At times, patients do not have typical whole body jerking, rather they just have a sudden brief jerk like a startle.
有时，患者并不会有典型的全身抽搐，而只是像惊吓一样突然的短暂抽搐。
This is also one of the minor seizure types.
这也是轻微的癫痫发作类型之一。
In majority of the patients, an attack may occur suddenly on top of normal ongoing activity but 25-30% of the patients may get a feeling that the attack is about to occur.
在大多数患者中，发作可能在正常正在进行的活动之上突然发生，但25%-30%的患者可能会感觉到发作即将发生。
This feeling is called an 'aura'.
这种感觉被称为“光环”。
Such a patient would him or herself tell you that they experience a peculiar phenomenon before a seizure starts.
这样的病人会告诉你，在癫痫发作开始之前，他们会经历一种特殊的现象。
Some patients may even take protective action like sitting on the floor or get away from a dangerous place when they experience an aura.
一些患者甚至会采取保护措施，比如坐在地板上，或者当他们感受到气场时，远离危险的地方。
70% of the people will not get a warning and the attack occurs suddenly.
70%的人不会得到警告，袭击发生得很突然。
Epileptic fits are usually of short duration.
癫痫发作通常持续时间较短。
Even before you can try any remedial action, a fit usually ends on its own.
甚至在你可以尝试任何补救措施之前，发作通常就会自行结束。
Another peculiar thing is that 99% of the people get back to their normal self within 15-30 minutes after a seizure as if nothing happened or at least no permanent damage has occurred to the brain.
另一件奇怪的事是，99%的人在癫痫发作后15-30分钟内恢复正常，就好像什么都没有发生，或者至少没有对大脑造成永久性损害一样。
So, this is a noticeable aspect of epilepsy that in case of a seizure, the brain loses its functionality during the event and then gets back to the level as it was before the fit.
因此，这是癫痫的一个值得注意的方面，在癫痫发作的情况下，大脑在发作期间失去功能，发作结束会恢复到发作前的水平。
If a person has some or all of these problems, he may be suspected as having epilepsy.
如果一个人有这些问题中的一部分或全部，他可能被怀疑患有癫痫。
For a formal diagnosis, a physician requires training.
对于正式诊断，医生需要经过培训。
Neurologists are expert in dealing with this disease.
神经科医生是治疗这种疾病的专家。
Sometimes, a test is done to make the diagnosis of epilepsy, which is called as EEG.
有时，需要做一项测试来诊断癫痫，这就是所谓的脑电图。
During EEG, electrodes are applied on the scalp which then record the brain's electrical activity.
在脑电图过程中，电极被施加在头皮上，然后记录大脑的电活动。
An EEG may show abnormality in the brain waves and it is then helpful in diagnosing epilepsy or its subtype in a patient.
脑电图可以显示出脑波异常，从而有助于诊断癫痫或其亚型。
