What is a distinguishing feature of generalized seizures?

• A. They affect only one hemisphere of the brain
• B. They involve the entire brain from the onset
• C. They are always preceded by an aura
• D. They are immediately followed by a specific postictal state

Answer: (B)

Generalized seizures are characterized by their involvement of the entire brain from the onset, which is the key aspect that distinguishes them from other types of seizures. This means that the electrical disturbance affects both hemispheres simultaneously right from the beginning rather than starting in one area and then spreading, as seen in focal seizures. This widespread involvement can result in various symptoms, including loss of consciousness, muscle stiffening, and convulsions, depending on the specific type of generalized seizure. The immediate and full brain engagement is crucial to understanding the impact and management of these seizures. In contrast, other features outlined in the options do not apply to generalized seizures. For instance, they do not solely affect one hemisphere, nor are they always preceded by an aura, which is more typically associated with focal seizures. Additionally, while generalized seizures may have a postictal state, it is not always specific or uniform across all individuals. Hence, the broad involvement from the outset remains the defining and distinguishing feature of these types of seizures.
