### input:
I m 19 years old, aside from asthma, a soft systolic heart murmur and dizziness I m normally fit and well. The other night I was on first aid duty at the open air theatre for a status quo concert and just over an hour before the end I was sat in a chair in the first aid post and my head went *funny* I felt likeiI wasn t really with it and I felt lightheaded. I gradually got worse over the next hour as my hands started shaking which got worse then just stopped, I was confused and disorientated. I had barely any energy and it was difficult trying to move and I was having problems talking and at one point couldn t speak at all. I kept zoning out or there would be times when I knew people were talking hut didn t know if they were talking to me or even what they were saying. I was taking to the hospital by our ambulance crew where I had an ECG done which was normal and my blood sugars were normally but I m not sure about anything else. I don t remember a lot of what happened, some of this is what I have been told by my colleagues. I currently work in a theme park for which I do a 40 mile round trip on a moped as well as having several other first aid duties to cover this season so I would be very grateful for an opinion on this and what I could do to stop it happening again.

### output:

Hello! I read your question and understand your concern! In my opinion these troubles may be caused by epilepsy. But epilepsy is not commonly lasting for hours, but minutes, and it can leave disorientation and weakness for hours after a seizure. Although repeated partial seizures can occur. Another cause would be a panic attack. I would recommend a EEG to check for epilepsy, and a brain MRI to rule out possible cerebral lesions. Hope to have been helpful! Best wishes
