Epilepsyis a seizure disorder affecting 1 to 2 percent of the population and is associated with abnormal electrical impulses from the neurons in the brain. These abnormal impulses cause recurrent, unprovoked seizures. The severity and type of seizures can vary widely among individuals, ranging from brief lapses in attention or muscle jerks to severe and prolonged convulsions. Diagnosis typically involves an electroencephalogram (EEG) to detect abnormal brain activity, along with imaging tests like MRI or CT scans.
