Only 25% of people who experience<unk> izures or<unk>  have epilepsy. The following is a list of possible causes: * Stroke * Hemorrhage * Intoxicants or adverse reactions to drugs * Insufficient dosage or sudden withdrawal of a medication (especially anticonvulsants) *Insufficient dosage or sudden withdrawal of benzodiazepine(s) medication (akin to alcohol withdrawal); itself a class of antiseizure/anticonvulsant medications * Consumption of alcoholic beverages while on an anticonvulsant, or alcohol withdrawal * Dieting or fasting while on an anticonvulsant * Starting on a new medication that reduces the effectiveness of the anticonvulsant or changes drug metabolism, decreasing its half-life, leading to decreased blood concentrations * Developing a resistance to an anticonvulsant already being used * Gastroenteritis while on an anticonvulsant, where lower levels of anticonvulsant may exist in the bloodstream due to vomiting of gastric contents or reduced absorption due to mucosal edema * Developing a new, unrelated condition in which<unk> izures are coincidentally also a symptom, but are not controlled by an anticonvulsant already used * Metabolic disturbances—such as affected kidney and liver * Sleep deprivation of more than a short duration is often the cause of a (usually, but not always, temporary) loss of<unk> izure control *Dehydration – moderate- to<unk> vere, especially when combined with any single factor above
