A neurological condition causing 15 or more headache days per month, often with severe pain, nausea, and sensitivity to light and sound.

Overview

Chronic migraine is a neurological condition characterized by experiencing 15 or more headache days per month, with at least 8 of those having migraine features. Migraines are not just bad headaches — they are complex neurological events that can cause severe throbbing pain, nausea, visual disturbances, and extreme sensitivity to light, sound, and smell. Migraines can affect children, teens, and adults. In children, migraine pain may be bilateral (both sides) and shorter in duration. Chronic migraine can develop from episodic migraine over time, often driven by medication overuse, stress, or other triggers. While not always curable, chronic migraine can be managed with a combination of preventive treatments, lifestyle modifications, and acute (rescue) medications.

Common Symptoms

Symptoms include: • 15+ headache days per month • Throbbing or pulsating pain, often on one side • Nausea and vomiting • Sensitivity to light (photophobia), sound (phonophobia), and smell • Visual disturbances (aura) in some patients • Fatigue and difficulty concentrating • Symptoms that worsen with physical activity Migraine attacks can last from hours to days and may leave patients exhausted afterward.

Diagnosis

Diagnosis involves: • Detailed headache history (frequency, duration, characteristics, triggers) • Neurological exam • Headache diary tracking • Ruling out secondary causes (imaging if red flags present) Chronic migraine is defined as 15+ headache days/month for 3+ months, with 8+ migraine days.

Current Treatments

Treatment includes: • Preventive medications (beta blockers, anti-seizure medications, antidepressants, CGRP inhibitors) • Acute medications (triptans, CGRP antagonists, anti-nausea medications) • Botox injections for chronic migraine • Lifestyle modifications (regular sleep, hydration, stress management, trigger avoidance) • Cognitive behavioral therapy • Avoiding medication overuse (which can worsen chronic migraine) A headache specialist can develop an individualized treatment plan.

Research Summary

Migraine research has advanced significantly, with the discovery of CGRP (calcitonin gene-related peptide) leading to new, targeted treatments. Studies continue to explore the genetic, vascular, and neurological factors underlying migraine. More research is needed on migraine in children and on the transition from episodic to chronic migraine.

Community Resources

Migraine is one of the most common and disabling conditions worldwide, yet it is often dismissed. Connecting with migraine advocacy communities can provide validation, education, and support. Explore our Stories page and community resources.
