Cluster Headache
Treatment and Care Options
Managing cluster headaches requires identifying triggers and establishing a preventive treatment plan. Because the pain is so severe, treatment is often divided into acute relief and preventative management.
Acute Treatment (During a headache episode):
Many doctors recommend high-flow oxygen therapy (100% oxygen) delivered through a mask, as this can rapidly constrict blood vessels and relieve pain. Other fast-acting medications, such as triptans or injectable oxygen, may also be prescribed.
Preventative Treatment (To reduce frequency):
To stop the clusters from happening, doctors often prescribe daily medications such as verapamil, lithium, or specialized CGRP inhibitors. It is crucial to take these preventative medications every day, even when you feel well, to keep the pain cycles under control.
What Causes Cluster Headache?
The exact cause of cluster headaches is not fully understood, but they are believed to be related to fluctuations in brain chemistry and blood vessel activity. They tend to occur in cycles or 'clusters' for periods of time.
- Changes in brain signaling and chemistry.
- Stress, alcohol, and changes in sleep patterns are common triggers.
- A combination of genetic and environmental factors.
