Verified step by step guidance

1. Understand the definition of a focal-onset aware seizure: it is a type of seizure that begins in one specific area of the brain and during which the person remains conscious and aware.
2. Recognize that in focal-onset aware seizures, consciousness is preserved, meaning the individual is aware of their surroundings and can recall the event.
3. Note that sudden loss of consciousness is not characteristic of focal-onset aware seizures; this typically occurs in focal-onset impaired awareness seizures or generalized seizures.
4. Understand that complex automatisms (repetitive, involuntary movements) may occur but are not always present in focal-onset aware seizures.
5. Be aware that seizure activity does not always spread immediately to both hemispheres in focal-onset aware seizures; it can remain localized.
