Migraine Headache | Cannabis Wiki
A migraine headache is a recurring, pulsating, vascular headache usually developing on one side of the head; characterized by a slow onset that may be preceded by an “aura” during which a sensory disturbance occurs, such as confusion or some visual interference.
The pain intensity gradually becomes more severe and may be accompanied by nausea, vomiting, irritability, fatigue, sweating, or chills.
Migraines occur at any age with more frequency in females and those with a positive family history for migraine headaches. There is an increase in migraine headaches during periods of stress and crisis as well as a correlation with the menstrual cycle. Dilation of the vessels in the head along with a drop in the serotonin level (which acts as a vasoconstrictor and a neurotransmitter, aiding in nerve transmission) occur at the onset of the migraine, which may last for hours or for days.
Treatment for migraine headaches includes medications to prevent the onset of the headaches and medications to relieve the headache and diminish or reduce the severity of the symptoms.
