• Third nerve palsy. This disorder can cause a closed or partially closed eyelid, an enlarged pupil, and the movement of the eye outward and downward.
• Trigeminal neuralgia. Trigeminal neuralgia is a disorder of the fifth cranial nerve and typically causes pain on one side of the face.
• Fourth nerve palsy or superior oblique palsy. This disorder can cause misalignment of the eyes and can affect one or both eyes.
• Sixth nerve palsy or abducens palsy. This type of palsy can cause the eye to cross inward toward the nose.
• Bell’s palsy. Bell’s palsy, a disorder of the seventh cranial nerve, can cause temporary weakness or paralysis in one side of the face.
• Hemifacial spasm. A hemifacial spasm happens when blood vessels constrict the seventh cranial nerve and cause a facial spasm or tic.
• Glossopharyngeal neuralgia. This condition affects the ninth cranial nerve and can cause pain at the base of the tongue that may travel to the ear and neck.
• Cranial base tumors. These are tumors that can form in the skull and affect different cranial nerves.
