Epilepsy at altitudes

Abseiling

There is a theoretical risk that being at high altitudes (above 3,500 metres/11,666 feet) can cause fluid retention. For someone with epilepsy, fluid retention could trigger seizures. However, the risk of this happening is considered to be very small.

 

Comments

I'd just like to mention that I have been skydiving for 8 years and have made 650 jumps and it has never affected my epilepsy (ie made me more likely to have a grand mal or petit mal seizure).
I couldn't comment on more prolonged exposure however such as working as a pilot.
