What is a seizure disorder commonly referred to as?

A seizure disorder is commonly referred to as epilepsy. Epilepsy is a neurological condition characterized by recurrent, unprovoked seizures, which result from abnormal electrical activity in the brain. This condition can manifest in various forms, with different types of seizures that can affect a person's awareness, movements, and overall behavior.

The other terms in the options refer to different conditions. Athetosis involves involuntary movements due to basal ganglia dysfunction and is not specifically a seizure disorder. Cerebral palsy is a group of disorders affecting movement and muscle tone or posture, caused by damage to the developing brain, and does not directly equate to seizures. Spina bifida is a birth defect where there is incomplete closing of the spine and membranes around the spinal cord, and while it can be associated with neurological issues, it is not synonymous with seizure disorders. Thus, epilepsy is the correct term for a seizure disorder.
