Focal Onset Seizures (Partial Seizures)

What is a focal onset seizure?

人脑通过通过神经细胞的神经元发送电信号来工作。当突然发生混乱的电活动时，就会发生癫痫发作。这会引起许多身体症状，例如肌肉收缩，视觉障碍和停电。

癫痫发作会影响整个大脑。局灶性发作癫痫发作，也称为部分癫痫发作，是癫痫发作仅在一个区域开始的时候。

A focal onset seizure may occur for many reasons.癫痫,brain tumors, or damage from head trauma or from a stroke can cause recurrent focal onset seizures. Infections, heatstroke, or低血糖can trigger a seizure.

Aseizure可以被治疗。诊断和治疗根本原因可以帮助减少局灶性癫痫发作的数量。大多数经历癫痫发作的人能够通过适当的治疗来过正常的生活。

癫痫发作的类型

癫痫发作 is the result of experiencing disorganized or erratic electrical activity in the brain. The electrical disturbance can produce a variety of physical, behavioral, or cognitive symptoms.

This is especially true with a focal onset seizure, which is a seizure that’s focused in just one part of the brain. This is also called a focal seizure, but it can change into a generalized seizure, which affects the entire brain.

There are two types of focal onset seizures. But there often is not a clear distinction between them.

You won’t lose consciousness during a focal onset aware seizure, or simple partial seizure, and it’ll last for a minute or less.

You might remember what happened after the seizure passes, but many people do not remember what occurred during their own focal onset impaired awareness seizure. These seizures can sometimes cause you to feel fearful or anxious.

Focal impaired awareness

在焦点发作中，您可能会失去意识，或者是复杂的部分癫痫发作。您也不会记得发生了什么。复杂的癫痫发作可以持续一两分钟，您可能会感觉到一个警告信号，就像癫痫发作前的不安或恶心一样。癫痫发作后，您可能会感到困倦和困惑。

什么原因导致局灶性癫痫发作？

There are many different conditions and situations that can cause seizures of any type. Sometimes, the cause is never discovered. A seizure without a known cause is called an idiopathic seizure.

Some of the possible 原因 of focal seizures are:

• 癫痫
• 肝或者肾功能衰竭
• 非常高血压
• use of illegal drugs
• 大脑发生ctions, likemeningitis
• brain and head injuries
• congenital brain defects，是出生前发生的大脑缺陷
• stroke
• 中毒或有毒的叮咬或刺
• 中暑
• 低血糖
• 退出毒品或alcohol
• 苯酮尿症, which is a genetic disorder that causes brain damage and mental disability

What are the symptoms of a focal seizure?

由于局灶性癫痫发作仅影响大脑的一部分，因此症状取决于特定事件。例如，如果扰动在大脑中影响视力的一部分，则可能会有幻觉或看到明亮的灯光。

局灶性癫痫发作的其他可能症状 包括 :

• muscle contractions, followed by relaxation
• contractions on just one side of your body
• unusual head or eye movements
• 麻木，刺痛或感觉到某物在您的皮肤上爬行
• 腹痛

What are the treatments for focal seizures?

焦点癫痫发作通常只能持续很短的时间，因此通常没有时间在发生它时进行治疗。更长的癫痫发作，称为癫痫持续状态，是罕见但危险的，需要紧急治疗。如果除了癫痫病（例如感染）之外，还需要相应治疗这个根本原因。

如果治疗潜在的疾病后，或者是由特发性癫痫，中风，脑肿瘤或其他脑损伤引起的，则需要抗癫痫药物以防止更多的癫痫发作。

如果有人扣押了任何类型，那就是 helpful to keep other people and objects out of the way until the seizure is over. Involuntary muscle contractions can cause someone who’s having a seizure to accidentally become injured.
