The symptom associated with a sudden onset of severe headache is not typically related to facial nerve palsy. Facial nerve palsy, commonly manifesting as dysfunction of the seventh cranial nerve, usually presents with symptoms directly linked to the facial musculature and sensations.

Loss of taste is often noted because the facial nerve also carries taste sensations from the anterior two-thirds of the tongue. This would indicate a potential involvement of the nerve pathways. The inability to close one eye stems from weakness in the orbicularis oculi muscle, a direct result of facial nerve impairment, making it a hallmark symptom of facial nerve palsy. Additionally, individuals with this condition commonly exhibit loss of control over facial muscles, which is a significant characteristic as it affects expression and movement.

In contrast, a sudden and severe headache may suggest various other neurological or systemic issues, such as migraines, subarachnoid hemorrhage, or increased intracranial pressure, and is not indicative of facial nerve dysfunction. Therefore, this symptom is clearly distinct from those associated with facial nerve palsy.
