Epileptic seizures are abnormal synchronous electrical discharges from specific neuron populations.
The precise location of these neuron clusters determines a patient's symptoms. Brain injury of many types can result in recurrent seizures. Common etiologies of the epilepsies are head injury, encephalitis, meningitis, genetic, hemorrhagic and ischemic infarcts, and brain tumors. These new drugs and formulations offer the potential for improved seizure control and less disagreeable side effects. The proven value of these medications comes as a result of enormous efforts by pharmaceutical companies, clinical researchers, and willing patients.
