What type of headache is characterized as pulsatile?

A headache that is pulsatile is most commonly associated with migraine headaches. Migraines are often described as throbbing or pulsating in nature, typically occurring on one side of the head. This characteristic pulsatility is a result of vasodilation and increased blood flow, which contribute to the pain experienced during a migraine attack.

Additionally, migraines may also present with other symptoms such as nausea, sensitivity to light and sound, and can be preceded by an aura in some individuals. This combination of symptoms helps differentiate migraines from other types of headaches.

In contrast, cluster headaches are characterized by excruciating, sharp pain and are often described as burning or stabbing rather than pulsatile. Tension headaches tend to cause a dull, aching sensation and a feeling of tightness or pressure, which is different from the throbbing nature of migraines. Sinus headaches are typically associated with sinus congestion and pressure, producing a more constant pain rather than a pulsatile one. Thus, the distinctive pulsating quality is what firmly associates this characteristic with migraine headaches.
