Seizure can be controlled by medication temporarily so sudnot be an issue while travel, no insurance will cover preexisting health issues , so it's waste of time to worry about it . Carry all necessary medication from Nepal including antibiotics and put her in strict discipline ( eating habits , medication etc ) n c will be fine .

The worst outcome is you have to rush her emergency in sever conditions.hospital cannot deny her treatment ..no temporary visitor ever pays emergency bills that comes in thousands .
