Cluster headaches and migraines both cause pain, but they are two different conditions. A cluster headache is a headache that occurs several times in a day, and is short in length and very painful. Cluster headaches may only affect one side of the head and pain is usually felt around the eyes.
Cluster headaches can occur any time of the day but typically occur or worsen in the fall or spring months (during season changes). Cluster headaches can last for days or months, and then go into remission so a person doesn’t experience them for quite some time.
Cluster headaches affect one in every 1,000 people and occur in men more than women. A person who suffers from cluster headaches can experience them up to three times a day.
A migraine can cause severe and intense head pain and symptoms such as nausea, vomiting, temporary vision loss, pain behind the eyes, sensitivity to light and sound and pain in the temples. There are two types of migraine headache: migraine with aura and migraine without.
Migraine with aura refers to sensations experienced with the onset of a migraine, such as feeling less mentally alert, seeing flashing lights or unusual lines, tingling or numbness and unusual smells or tastes.
The difference between cluster headaches and migraines is vast, for example, cluster headaches occur numerous times a day, while a migraine headache is not a daily occurrence, and if it does occur, it is just once.
Both migraine and cluster headaches are mainly experienced on one side of the head; however, migraines can affect other sensations, which is something cluster headaches do not do.
The exact cause of cluster headaches is not fully understood. Some neurologists believe they occur due to greater activity in the hypothalamus – a part of the brain that controls temperature, hunger and thirst. This area of the brain may also be responsible for widening blood vessels, which causes greater blood flow to the brain and can lead to headaches.
Unfortunately, if this is the cause of cluster headaches, researchers are still unaware as to why the hypothalamus acts in this way.
