Cluster Headaches

Causes and Treatment of Cluster Type Headaches

Almost everyone will suffer from some form of headache throughout their life, which doesn't result from some underlying medical condition. These will either be migraine, tension or cluster headaches.

A cluster type headache is the least common of the primary headaches but is by far the most painful.

This type of headache has even been dubbed the suicide headache due to the fact that some cluster headache sufferers have eventually resorted to this, as a way of ending the pain.

• Cluster type headaches get their name because the headaches tend to occur in clusters.
• They will happen several times per day, lasting for the same amount of time and occuring at the same time per day.
• They tend to linger for several weeks, will dissipate and then recur with the same frequency and intensity.

Cluster headaches are much more severe than migraine or tension headaches and often strike without warning on one side of the brain only (unilateral), with pain behind the eye of the affected region. The pain tends to last for an hour or less but the headaches strike several times each day.

The cause of cluster headaches is unknown but what is known is that the blood flows abnormally in the affected area, causing the blood vessels to dilate and this in turn puts pressure on the trigeminal nerve.

Sufferers of this type of headache generally find relief by staying active, rather than motionless, as with migraine or tension headaches.

Cluster Headache Diagnosis

In order to diagnose this type of headache your doctor should perform a physical examination as well as a medical history, as some cluster headaches are genetic. Your doctor may also run a CT or MRI to rule out any secondary condition causing the headache.

Just like migraines, cluster headaches are regarded as episodic or chronic.

There is a seasonal rhythm to this headache type and many headache sufferers are affected more during the spring or fall.

The headaches generally occurs several times a day at the same time of day, with many activated during REM (rapid eye movement) sleep. This is why some sufferers will try NOT to sleep to avoid the headache, but that just keeps the cycle going.

Several studies have been performed on cluster headache sufferers and one common theme has come forward - sleep apnea and excessive snoring seem to be the most common triggers. Both of these involve a lack of oxygen to the brain. Once this condition was treated, researchers found that the cluster headaches subsided, most of the time.

While pain relief medication is most often prescribed to treat the problem, most pain medication will only relieve the pain - it won't prevent the headache or cure the cause.
