What happens during a seizure inside the brain?
Seizures are caused by chemical changes in your body that affect the way your nerve cells talk to one another. This leads to sudden electrical activity inside your brain that can last a few seconds or several minutes. While there are many different types of seizures, they often follow the same pattern.
What part of the brain is affected by seizures?
The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch. Frontal lobe seizures are a common form of epilepsy, a neurological disorder in which clusters of brain cells send abnormal signals and cause seizures. These types of seizures stem from the front of the brain.
Can you be conscious during a seizure?
In focal aware seizures (FAS), previously called simple partial seizures, the person is conscious (aware and alert) and will usually know that something is happening and will remember the seizure afterwards. Some people find their focal aware seizures hard to put into words.

What does an absence seizure look like?

What kind of seizures are caused by stress?
Pseudoseizures, also called psychogenic nonepileptic seizures (PNES), are seizures that occur as a result of psychological causes, such as severe mental stress.
How do you tell the difference between a seizure and a Pseudoseizure?
Evidence-based answer. During an attack, findings such as asynchronous or side-to-side movements, crying, and eye closure suggest pseudoseizures, whereas occurrence during sleep indicates a true seizure.
