Which statement BEST describes a simple partial seizure?

• A. A Seizure That Is Not Preceded By An Aura
• B. A Generalized Seizure Without Incontinence
• C. A Seizure That Causes The Patient To Stare Blankly
• D. A Seizure That Begins In One Extremity

Answer: (D)

Simple partial seizures are focal events that start in a specific area of one hemisphere, and the person remains fully aware during the seizure. When the focus is in the motor cortex, you often see unilateral motor signs that begin in one limb and may progress to nearby areas (a Jacksonian march). This makes a seizure that begins in one extremity the best description, because it reflects a localized onset with preserved consciousness.

An aura can occur with focal seizures but isn’t required, so not having one doesn’t define it. Staring blankly describes absence seizures, which are generalized and involve brief impairment of consciousness, not a focal, unilateral onset.
