MRCP2-3210

A 14-year-old boy comes to the clinic with a history of a single seizure that occurred without warning after a family gathering. Upon further questioning, he reports experiencing episodes of blank spells for the past six years and brief shock-like contractions of his upper limbs several times a month, particularly during breakfast. There are no significant medical or family histories, and physical examination is unremarkable.
