Final answer:
The correct answer is E. Mild to moderate intensity, as migraines usually have a moderate to severe intensity, which is a key diagnostic criterion differentiating them from other types of headaches.
Step-by-step explanation:
The question posed is related to the diagnostic criteria for a migraine without aura. Among the listed options, the correct answer for the one that is not a diagnostic criterion of migraine without aura is E. Mild to moderate intensity. The diagnostic criteria for migraines without aura typically include the headache lasting between 4 to 72 hours (A), having a pulsatile quality (B), being associated with photophobia (C), and often accompanied by nausea and vomiting (D). However, the intensity of a migraine is typically moderate to severe, rather than mild to moderate. This is what differentiates migraine headaches from other types of headaches, like tension or sinus headaches.
