Verified step by step guidance

1. Understand the classification of seizures: Seizures are generally categorized into two main types based on the area of the brain they affect—partial (or focal) seizures and generalized seizures.
2. Partial (or focal) seizures originate in a specific, localized area of one hemisphere of the brain, affecting only one side initially.
3. Generalized seizures, on the other hand, involve both hemispheres of the brain from the onset, meaning they affect both sides simultaneously.
4. Absence seizures are a subtype of generalized seizures characterized by brief lapses in awareness, and they affect both sides of the brain.
5. Therefore, the type of seizure that affects both sides of the brain is a generalized seizure, as it involves widespread brain activity rather than a localized area.
