What seizure disorder is affecting 1 to 2 percent of the population and is associated with electrical impulses from the neurons of the brain?

Epilepsy is the correct answer because it is a seizure disorder that affects about 1 to 2 percent of the population. It is caused by abnormal electrical impulses from the neurons in the brain and can result in seizures. Spina bifida, glaucoma, and tendonitis are not seizure disorders and do not involve electrical impulses from the brain's neurons, so they are incorrect choices. Spina bifida is a congenital condition affecting the spine and glaucoma is a condition affecting the eyes. Tendonitis is inflammation of the tendons and is not associated with any brain activity.
