Epilepsy refers to the medical condition of recurrent, unprovoked seizures. Epilepsy and seizures are the most common neurologic disorder. Up to 10% of the population will experience a seizure at some point in their life, with most not being diagnosed with epilepsy. A seizure is a sudden change in behavior accompanied by an abnormal discharge of electricity in the brain. A seizure is typically brief and can present in many different ways, including motor changes, sensory phenomena, and alterations in consciousness. Seizures are a symptom of a neurological problem; thus, just as with a symptom such as headache, there are many reasons why a seizure may occur. High fever, meningitis, toxins, chemical imbalances of glucose or electrolytes, stimulant overdose, massive sleep deprivation, and alcoholic withdrawal are all examples of external events that can provoke a seizure.
