Not Everything That Shakes Is a Seizure: A Case Report
Todd E Jones1, Jean E Cibula2, Don Bohannon1
1From the Departments of Anesthesiology.
Not everything that shakes is an epileptic seizure. We present a patient who repeatedly exhibited severe shaking at emergence from general anesthesia. Her nonepileptic myoclonus was mistaken for a refractory seizure and treated with benzodiazepines and intravenous anesthetics. The resulting depressed level of consciousness rendered myoclonus clinically indistinguishable from refractory seizures. Over the course of 6 procedures, we found that levetiracetam, a first-line antiepileptic drug, effectively suppressed her myoclonus. The episodic nature of perioperative anesthesia care presents a challenge for differentiating myoclonus from seizure while balancing the concerns raised by different surgical procedures, rare comorbidities, and the subjective patient experience.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
