A 28-year-old woman presents to her primary care physician with diplopia on horizontal gaze, and dizziness. She reports that these symptoms began approximately 2 weeks ago, and has never happened before. Her double vision is only elicited when looking towards the left, but is absent with primary gaze. She states that approximately 4 months ago, she had right lower extremity weakness and numbness that lasted one week before being completely resolved. Medical history is significant for migraine headache with aura that is adequately treated with ibuprofen. On physical examination, there is impaired adduction of the right eye, with contralateral disassociated horizontal nystagmus of the abducting eye. There is normal convergence and diminished vertical gaze holding. A postural tremor is also noted on examination. Laboratory tests are significant for a normal B12 and thyroid-stimulating hormone (TSH) level, and normal white cell count. MRI of the brain is shown.

A 15-year-old female presents to the emergency department with a seizure. While she was eating her breakfast in the morning, her mother witnessed myoclonic jerks involving the upper extremities.

She is currently sexually active with her boyfriend and uses condoms as her only form of contraception. On physical exam, there is evidence of recent tongue biting, no focal neurological deficits, and normal intelligence. A sleep-deprived EEG is performed with interictal findings showing generalized 4-5-Hz polyspike and slow-wave discharges, with activation during photic stimulation (photoparoxysmal response). MRI of the brain is normal. Which of the following is the best treatment option for this patient?
