Understanding Cluster Headaches
A cluster headache, clinically referred to as a type of trigeminal autonomic cephalalgia, is one of the most painful experiences a human can have.
These attacks don’t last long — 15-30 minutes — but occur in clusters or groups.
You may have between one and eight episodes a day for several weeks or even months.
Most patients have remission periods between clusters. The onset of cluster headaches is typically between the ages of 20-40.
The causes of cluster headaches aren’t fully understood.
Some research indicates that abnormal activity in the hypothalamus causes blood vessel dilation and increased circulation in your brain.
Some other triggers for cluster headaches include sudden increases in temperature, exercising in hot weather, and alcohol.
