History and Physical — Patient 27
Present Illness: Patient #27 is a previously healthy 10 year old Caucasian male, transferred from another facility to Texas Children's Hospital emergency center for evaluation of sudden speech arrest. The incident occurred approximately four hours prior to evaluation while the child was in school; he raised his hand to answer a question, and when called upon, was not able to express his thoughts (though he was fully cognizant of his surroundings and situation). The episode lasted approximately 30 seconds and resolved spontaneously with full recovery of function. There was no loss of consciousness, abnormal movements, visual impairment, vertigo, numbness, or weakness.
In the emergency center, the child experienced a similar episode, lasting less than 30 seconds and characterized by inability to express his thoughts, left facial droop, left arm numbness, and left arm weakness. The symptoms again resolved completely.
Over the following 24 hours, the child experienced seven additional episodes of a similar character. Most episodes resolved spontaneously within 30-60 seconds following onset. The final episode, however, resulted in sustained deficits.
The patient suffered no intercurrent illnesses, fever, diarrhea, or head trauma.
Past Medical History: Two weeks prior to evaluation, the child had a mild upper respiratory infection with a sore throat. He also had a clinically confirmed (seen by a pediatrician) case of chicken pox one month ago. Within the past year, he has suffered occasional headaches. His birth and developmental history were normal. Immunizations were up to date.
Past Surgical History: None.
Allergies: No known drug allergies.
Family History: There is no history of seizures, migraine headaches, or strokes. No female family member has had a miscarriage. His parents, 14 year old sister, and seven year old brother were in good health.
Social History: He attends fourth grade and receives A and B grades. There is no history of substance abuse and no recent travel exposures.

|II||Visual acuity 20/20; visual fields were full; fundoscopic exam was WNL; pupils were 4 mm and reactive.|
|III / IV / VI||Extraocular movement were full; there was no nystagmus or ptosis.|

After seven episodes of brief weakness and numbness over the initial 24 hour observation period, however, the child's physical examination changed. He now showed a mild left facial droop (central) with decreased left nasolabial fold, mild dysarthria, and numbness and weakness of the left arm and leg. Strength testing in the upper extremities at that time showed:
The patient also demonstrated some difficulty standing. When he walked, he tended to drag his left leg and lean to the left side.
