Patients may present with consciousness problems, headaches, nausea, visual defects, fatigue, disturbance of eye movements and pupillary reflexes, or coma.
Neurologic examination should assess cognitive and mental abilities, cranial nerve function, motor function, deep tendon reflexes, sensory function, coordination, and gait (if appropriate).
