There are numerous types of headaches, but the most common are tension-type headaches and migraine. Tension-type headaches are commonly described as a band-like sensation around the head. These headaches are usually triggered by stress, generally mild in severity and easily treated with rest or over-the-counter remedies. Migraines tend to be more severe, more long lasting, and are often resistant to over-the-counter medications.
Approximately 6% of men and 18% of women have migraine, making it the most common neurologic condition. Characteristics that differentiate a migraine headache from a tension headache include a tendency for the headaches to affect one side of the head. Migraines are also often accompanied by nausea, light sensitivity and sound sensitivity and many migraine sufferers will retreat to a dark, quiet room during a headache.
