One of the diagnostic criteria for a migraine attack is that the headache must last between 4 and 72 hours if untreated. This timeframe is crucial because it helps distinguish migraine from other types of headaches, such as tension-type headaches, which may last longer but do not have the same intensity or accompanying symptoms. The duration criterion is based on the understanding that migraines typically follow this pattern, providing a reliable framework for healthcare providers to recognize and diagnose the condition.

The classification emphasizes that if the headache persists beyond 72 hours, it may signify a different clinical situation or complications that would require further evaluation. By adhering to this duration standard, clinicians can ensure they are addressing true migraine attacks that align with established definitions, which inform both diagnosis and treatment approaches.
