A complex partial seizure can happen anytime and usually without much warning. They can even occur when the person is in the middle of an activity. Sometimes the person will have an aura right before having a complex partial seizure. An aura is also called a simple partial seizure. It can act as a warning signal that a bigger seizure is coming.
There are some additional factors that can trigger a seizure, including:
low blood sugar
reactions to some medications
However, for some people, the first sign is an aura. You might notice:
Strong emotions, like fear
Changes in your vision -- you might see colored lines or spots
Strange feelings or thoughts, like tingling or deja vu (the sense that you’ve been in the exact same situation before, even though you haven’t)
Commonly, a auditory hallucination (hearing a radio or something that isnt there)
During the seizure, you may suddenly stop what you’re doing and look off into space as if you’re daydreaming. But nothing will snap you out of it. You also may start to chew, smack your lips, mumble, or do other things over and over again. You may move in a stiff, mechanical way.
So, it depends.
