I have a question for you. How would you translate "non-epileptic"? Cosnautas has a translation for "psychogenic non-epileptic seizures (PNES)" and it is "convulsiones (o crisis paroxísticas) psicógenas" or "seudoepilepsia psicógena".
The issue is when I find terms like "non-epileptic seizure", "non-epileptic etiology", "non-epileptic event", or just plain "non-epileptic".

Examples:

- Patients having non-epileptic seizures typically have some awareness of their environment.
- The presence of a normal awake background on EEG during a period of unresponsiveness is highly suggestive of a non-epileptic event.
- Taken together the appearance is consistent with a psychogenic etiology rather than a different non-epileptic etiology.
- While the most common diagnostic error is misdiagnosis of PNES as epilepsy, there are also circumstances when an epileptic seizure is particularly likely to be misdiagnosed as non-epileptic, especially in “EEG negative” seizures.


I've been using the translation "...paroxísticas" so far, but I think I'm wrong since they are not necessarily non-epileptic. In that case should I translate it as "...no epiléptica" (except when talking about PNES)?
