Is there anything that could cause someone to have seizures by just breathing it in? I'm thinking of something that may have been left maliciously, say hidden behind a bed. I think the person having the seizures may already be predisposed to having epilepsy, but that something could have brought on grand mal seizures when all they'd previously had were absence seizures.
If not something left maliciously then just something that may have been left in the room (of a very untidy person!!) or some sort of environmental factor we could look at?
I think we've ruled out anything ingested due to the time span.
The background is: Relative has started having seizures and they seem more frequent if they sleep in this room. Also they started after dumping ex. When they were speaking to their Ex's Ex he also stated that he started having seizures after they dumped the Ex - we are assuming this as BS but need to rule it out.
