Which statement best describes simple partial (focal) epilepsy?

• A. Seizures with loss of consciousness and generalized convulsions
• B. Seizures that begin in one brain region with motor, sensory, autonomic, or psychic symptoms and preserved consciousness
• C. Seizures with postictal confusion
• D. Seizures that start as generalized tonic-clonic from onset

Answer: (B)

Simple partial seizures are focal seizures that start in a single region of the brain and do not impair consciousness. The abnormal electrical activity stays localized, so the person remains awake and aware during the event. These seizures can present with motor symptoms (such as a twitching that may spread along a limb), sensory phenomena (tingling, phantom smells), autonomic signs (epigastric sensation, sweating), or psychic experiences (deja vu, fear). Because consciousness is preserved, there isn’t the confusion or unresponsiveness seen after many other seizure types. Sometimes the activity spreads and the seizure becomes generalized, but the defining feature here is focal onset with preserved consciousness. Choices describing loss of consciousness with generalized convulsions, postictal confusion, or onset with generalized tonic-clonic activity do not fit this pattern.
