Chlorine Exposure and Seizures

Hi, I'm pretty new around here, and I really appreciate all of the great information. Some of it is applicable, and all of it is informative. Thanks. Anyway, my 5 year-old has been diagnosed with Focal Onset Seizures. She has had two Complex Partial Seizures in as many months, and is now on Keppra (after an alergic reaction to Trileptal). We're just waiting for the next one. In some of the research that I have done, I have found a couple of studies that linked Chlorine exposure to seizures. Most chlorine exposure research focuses on lung damage, but these focused on neurological damage that caused seizures. My question, is it possible to get elevated levels of exposure to Cholorine from a pool / hot tub? Daily use? Hot tub vapors? Over chlorination? All summer exposure? Another question might be "Do epilepsy diagnosis go up in the summer or among children who are exposed frequently to pools? I know this is a far reach, and there is no supporting research, that I have found on the relationship between pool use and epilepsy, but I thought that I would throw this out there and see if anyone else sees an similarities in their situation. Thanks again for the awesome information. Cris
