In young adults, a lumbar puncture (LP) for cerebrospinal fluid (CSF) analysis is completed to exclude meningitis in patients who have no history of diabetes or hypertension and who have a head scan negative for other pathology. Elderly patients should undergo blood testing for erythrocyte sedimentation rate (ESR), C-reactive protein, and platelets to screen for giant cell arteritis (temporal arteritis). Poor or no resolution of sixth nerve palsy should prompt a full neurologic evaluation.
