Some times one cannot tell difference between a migraine and a tension-type headache. Both can occur at irregular intervals. Also, in rare cases, both can occur daily or almost daily. Some time these three conditions co exist.
What causes migraine headaches
Although fatigue and stress can bring on both tension and migraine headaches, migraines can be triggered by certain foods, changes in the body\’s hormone levels, changes in sleep pattern and even changes in the weather.
There also are differences in how types of headaches respond to treatment with medicines. Although some over-the-counter drugs used to treat tension-type headaches sometimes help migraine headaches, the drugs used to treat migraine attacks do not work for tension-type headaches for most people.
The exact cause of migraine is not fully understood. Most researchers think that migraine is due to abnormal changes in levels of substances that are naturally produced in the brain. When the levels of these substances increase, they can cause inflammation. This inflammation then causes blood vessels in the brain to swell and press on nearby nerves, causing pain.
Genes also have been linked to migraine. People who get migraines may have abnormal genes that control the functions of certain brain cells.
