Re: Very First Grand Mal
Try and list ANY over the counter meds (diet pills) suppliments that may have been taken. If any stimulants were taken (caffine) or if the person drank a beer that evening at dinner. Any or all of these may have had an effect (or not).
The food that day and week before, try and write it down best you can. If it was normal meal or not. If meat was not cooked properly that could have been the problem if others were sick as well from the meal.
The environment the person was exposed to (possible toxins) could have caused an episode of this nature. Such as heavy metals, farming chemicals, fuels, etc. The bodies reaction to trying to rid itself of the toxins may appear to look like a seizure if it is a once only occurance (and not neurological).
Elongated exposure to chemicals can build up can cause a seizure like episode all of a sudden if the person has been in that environment for (years) a long time. Such industries are metal treating (plating, chrome, electro plating; when masks are not used) Heating industry (asbestos) (also in auto) (I had an uncle that suffered from chemical exposure in the auto industry).
Hope that helps you with some lines to follow.
