Presentation

Prevention

  • Learn about contraception and ways to prevent and ways to prevent problems during pregnancy. Other medications that have been used to treat this epilepsy include benzodiazepines like clobazam (Onfi) or clonazepam, and topiramate (Topamax).[epilepsy.com]

  • If you see a person having a seizure, take these steps: Roll the person onto his or her side to prevent choking. Cushion the head. Loosen any tight clothing around the neck. Keep the airway open.[de.slideshare.net]
  • Therefore closing both eyes does not prevent photosensitive reaction but on contrary may increase risk because of red-tinted light filtering through the eyelids.[epilepsygroup.com]
