What are the two types of seizures?

• A. General seizures: begin locally with variable consciousness.
• B. Partial seizures: the patient is always unconscious.
• C. General seizures: the patient is always unconscious and the movement is tonic-clonic; Partial seizures: begin locally and consciousness levels vary.
• D. Absence seizures are the only type.

Answer: (C)

Seizures are classified by where they begin in the brain. Generalized seizures start in both hemispheres from the onset, usually producing unconsciousness and often presenting with bilateral, sweeping motor activity such as tonic-clonic movements. Partial (focal) seizures start in a specific area of the brain and may have preserved consciousness (simple partial) or impaired consciousness depending on the region involved. This distinction captures the typical contrast: generalized seizures tend to involve unconsciousness and widespread motor activity, while partial seizures begin locally with consciousness varying based on the area affected. It’s worth noting there are other generalized seizure types (like absence, myoclonic, or atonic) that don’t always involve tonic-clonic movements, and some focal seizures can evolve to become generalized, but the two broad categories described are the standard framework.
