Migraine headaches are debilitating events for those that develop them regularly. Discuss the role of serotonin in migraines; include in your discussion effects on blood flow. Explain why it may be that people with migraines are more frequently diagnosed with depression and anxiety.
What will be an ideal response?
Serotonin levels are negatively correlated with blood flow to the brain, so low serotonin activity might produce the increased blood flow observed during headaches. Low serotonin is also correlated with depression and anxiety, and people with migraine headaches are more likely than others to also be diagnosed with these conditions. Reserpine depletes available serotonin, and is also associated with headaches.
