Abstract
Hypoglycemia can cause a variety of neurological symptoms ranging from mild confusion to seizures and coma. The brain depends heavily on glucose as its main energetic resource, and a decrease in glucose levels can lead to impaired cerebral function. A 38-year-old female presented to the Emergency department with a history of headache, dizziness and asymmetric reactive pupils in addition to bilateral medial strabismus, nystagmus and photophobia. A non-contrast brain Computed Tomography scan was performed showed no significant radiological findings. Laboratory tests were within normal ranges except for a clinically significant hypoglycemia (level II). Intravenous dextrose was administered and strabismus gradually resolved, and headache subsided gradually within an hour. Hypoglycemic state should be investigated first in any patient with sudden neurological deficit.
