Epilepsy can take many forms.
No matter how dramatic the seizure disorder appears on the outside, it almost always has a dramatic effect inside. An electrical misfiring in the brain causes epilepsy. The different types of seizures outlined above are determined by the location of the misfirings. These misfirings in the nervous system lead to symptoms ranging from abnormal sensations to convulsions. Approximately 70 percent of patients with epilepsy can control their seizures successfully with medication, but the remaining 30 percent fail to benefit from medication either because of a lack of seizure control or side effects of the medication, or both.
