To determine the correct answer, let's analyze each option step by step:

1. Starts in 1 hemisphere of the brain then spreads to the other, consciousness is lost.

   • This description is more characteristic of a focal seizure that can generalize, not an absence seizure.

2. Inherited, usually begins around ages 3 – 12 years old.

   • Absence seizures are indeed often seen in children and can have a genetic component. They typically begin in childhood, around the ages mentioned.

3. Difficult to identify where it begins and ends, yet it is long and occurs rarely.

   • Absence seizures are usually brief (lasting only a few seconds) and can occur frequently, not rarely. This description does not fit.

4. Begins in the frontal lobe and affects vision.

   • This description is more indicative of a seizure that affects the occipital lobe, which is responsible for vision, not an absence seizure.

Based on the analysis, the correct answer is: Inherited, usually begins around ages 3 – 12 years old.
