Cluster Headache Cluster headaches are different that typical headaches or migraines in that they begin intensely and last from 5 minutes to an hour. They may come several times during the day, punctuated by painless periods. The cause is unclear, but competing theories trace cluster headaches to either a malfunctioning vascular system in the brain, or a malfunctioning neurological symptom in the brain. A variety of drugs is used to treat cluster headaches.
