Multiple factors can trigger a seizure, including sleep deprivation, fever, substance use, stress and flashing lights, according to The Epilepsy Foundation. Some patients find that a specific time of day can spark a seizure. Hormonal changes, low blood sugar, certain medications and an excessive intake of caffeine can lead to seizures as well.
Most patients report that seizures are prone to occur in patterns or after specific situations, reports The Epilepsy Foundation. When a seizure occurs as a response to certain stimuli, this can be a sign of reflex epilepsy. One form of this condition is called photosensitive epilepsy, which is triggered by bright flashing lights. Certain noises can trigger a reflex seizure as well.
For patients with epilepsy, forgetting to take medication doses can result in a seizure, according to WebMD. Drinking a lot of alcohol or using drugs such as ecstasy or cocaine are other common factors that trigger a seizure. Doctors report that for around one out of two women who suffer from epilepsy, seizures usually occur more frequently when they have their menstrual periods.
A partial onset seizure affects a portion of the brain, and it can sometimes result in a loss of consciousness, says Healthline. Aside from the usual lifestyle triggers, conditions such as a brain infection, severe head trauma or a vascular disease can precipitate a partial onset seizure.
