Case Presentation

H.V., a 6 year old female is brought in to the clinic by her mother, who is concerned about her behavior at night and the possibility of seizures.

H.'s parents have recently noted nightly episodes of strange behavior. Usually, they will hear thrashing noises, which alert them to the problem. When they arrive in H.'s room, she is writhing about in her bed, with somewhat rhythmic, but difficult to describe movements of both her arms and her legs. At this time she is usually somewhat responsive, however she acts very terrified and is somewhat incoherent on questioning.

Cardiac- Regular rate and rhythm, no murmurs, rubs or gallops
Lung- Lungs are clear to auscultation bilaterally, breathing easily without accessory muscle use.
Abdominal- Soft and nontender, no masses are palpable.
Extremities- No clubbing, cyanosis or edema, warm and well perfused with capillary refill less than 2 seconds
