What Are Cluster Headaches?
Cluster headaches are considered one of the most severe headache disorders2 and are characterized by intense, stabbing pain typically localized on one side of the head or around one eye.3 These headaches occur in cyclical patterns or clusters, hence the name, and can last for weeks or months, followed by periods of remission.
Cluster Headache Symptom
The most notable symptom of cluster headaches is severe, burning, or piercing pain around or behind one eye. Other symptoms may include redness or tearing of the eye, nasal congestion, drooping eyelids, and restlessness. The pain often peaks within minutes and can last from 15 minutes to several hours, with multiple attacks occurring in a day during a cluster period.
Causes of Cluster Headaches
The cause of cluster headaches is unclear, but it is thought they are linked to abnormalities in the hypothalamus, a part of the brain that regulates sleep and biological rhythms. Triggers may include alcohol, bright lights, strong smells, altitude, exertion, heat, and certain medications.4 Genetic factors may also play a role, as cluster headaches sometimes run in families.
Diagnosing Cluster Headaches
Diagnosing cluster headaches involves thoroughly evaluating your symptoms, medical history, and a physical examination. According to the International Classification of Headache Disorders, diagnosing cluster headaches involves meeting specific criteria:5
- Number of Attacks: You must have experienced at least five separate headache attacks.
- Pain Characteristics: Each attack should involve severe pain on one side of the head, particularly around or behind the eye or in the temple area. The pain typically lasts between 15 minutes and 3 hours if untreated. During some periods, the pain might be less intense or vary in duration.
- Associated Symptoms: The headache must be accompanied by at least one of the following symptoms on the same side as the pain:
- Red or teary eyes
- Sweating on the forehead or face
- Nasal congestion or a runny nose
- Swollen eyelid
- Small pupil or drooping eyelid
- A feeling of restlessness or agitation
- Attack Frequency: The attacks should occur between once every other day to as many as eight times a day. In some cases, they may be less frequent during the active period of the headache.
- Exclusion of Other Conditions: The symptoms must not be better explained by another diagnosis.
Episodic Cluster Headache Criteria:
The headaches must meet the criteria for cluster headaches mentioned above and occur in periods (called cluster periods).
There should be at least two separate cluster periods lasting from 7 days to one year, with pain-free intervals of at least three months between them.
Chronic Cluster Headache Criteria:
- The headaches must meet the criteria for cluster headaches.
- The attacks continue without any pain-free remission periods, or if there are remissions, they last less than three months for at least one year.
Our specialists may recommend imaging tests, such as MRI or CT scans, to rule out other potential causes of the headache. Accurate diagnosis is crucial to developing an effective treatment plan.
Cluster Headache Treatment
Treatment for cluster headaches focuses on alleviating pain during attacks and preventing future episodes. Acute treatments may include oxygen therapy, triptan medications, or nerve blocks. In chronic cases, preventive strategies often involve medications such as calcium channel blockers, glucocorticoids, or even sphenopalatine ganglion, vagus, and occipital nerve stimulation. At DFW Spine Institute, we tailor treatment plans to each patient’s needs, ensuring comprehensive care.
