Which condition is characterized by recurrent seizure activity?

Epilepsy is characterized by recurrent seizure activity, which is a hallmark of the condition. Seizures in epilepsy result from abnormal electrical activity in the brain, leading to a range of symptoms from brief lapses in attention to severe convulsions. The recurrent nature of seizures distinguishes epilepsy from other neurological disorders.

In contrast, Parkinson's disease is primarily a movement disorder characterized by tremors, stiffness, and bradykinesia, but it does not typically involve seizures. Migraines can cause severe headaches and associated neurological symptoms, but they are not defined by seizure activity. Multiple sclerosis involves damage to the central nervous system and may cause various symptoms, including muscle weakness, but it is not primarily recognized for causing recurrent seizures as seen in epilepsy.
