Cluster Headache

Moderate

Cluster headache is a neurological disorder characterized by repeated attacks of extremely severe pain, usually around or behind one eye or on one side of the head. Attacks often begin suddenly and may last from several minutes to a few hours. They can occur repeatedly during periods known as cluster periods, sometimes at similar times each day. The affected eye may become red or watery, and the eyelid may swell or droop. A blocked or runny nose on the same side may also occur. Because the pain can be severe and recurrent, medical evaluation is important.

Overview

Cluster headache is a neurological disorder characterized by repeated attacks of extremely severe pain, usually around or behind one eye or on one side of the head. Attacks often begin suddenly and may last from several minutes to a few hours. They can occur repeatedly during periods known as cluster periods, sometimes at similar times each day. The affected eye may become red or watery, and the eyelid may swell or droop. A blocked or runny nose on the same side may also occur. Because the pain can be severe and recurrent, medical evaluation is important.

Causes

The precise cause of cluster headache is not fully understood. The condition appears to involve abnormal activity in brain regions and biological systems that regulate pain and circadian rhythms. The hypothalamus is thought to play an important role because attacks often occur at predictable times and may follow seasonal or daily patterns. During an active cluster period, alcohol can trigger an attack in susceptible people, and other individual triggers may also exist. Cluster headaches are not caused simply by stress or ordinary tension headaches.

Risk Factors

Cluster headache is more common in men than women and often begins in adulthood, although it can occur in anyone. A family history may increase susceptibility. Smoking has been associated with cluster headache, although the relationship is complex and smoking does not explain all cases. Alcohol can trigger attacks during an active cluster period in susceptible individuals. Attacks may also follow circadian or seasonal patterns. A person who experiences recurrent severe one-sided headaches with autonomic symptoms should receive medical evaluation.

Diagnosis

Diagnosis is based on a patient's medical history, symptoms, physical examination and, when necessary, laboratory or imaging investigations.
Cluster headache is diagnosed primarily from the characteristic pattern of attacks, including severe unilateral pain around or behind the eye, relatively short duration, repeated attacks, and associated symptoms such as tearing, nasal congestion, eyelid swelling, or restlessness. A detailed history and neurological examination are important. Imaging such as MRI may be recommended in some people, particularly when the headache pattern is new, unusual, or associated with findings that could suggest another neurological condition. There is no single blood test that confirms cluster headache.

Prevention

Key Prevention Tips
There is no guaranteed way to prevent cluster headaches because their underlying cause is not fully understood
People who experience cluster periods may identify individual triggers that reliably provoke attacks and can discuss avoidance strategies with a healthcare professional
Alcohol is a well-known trigger for some people during an active cluster period
Maintaining a consistent sleep schedule may also be useful because attacks can follow circadian patterns
Preventive medicines may be prescribed for people with frequent attacks, but treatment should be individualized by a clinician
