Cranial Nerve Exam Red Flags: Key Warning Signs to Watch For
Assessing the cranial nerves is a fundamental component of any neurological examination, providing a window into the integrity of the central and peripheral nervous systems. Observe the patient's gait, posture, and any facial asymmetry or abnormal eye movements, which can offer immediate clues regarding cranial nerve function.
For the facial nerve, ask the patient to perform a series of movements including forehead wrinkling, eye closure, smiling, and whistling, looking for symmetry and completeness. Shine a light into one eye and observe for direct constriction as well as consensual constriction in the opposite eye, noting any afferent or efferent defects.
