Chronic Migraine

Overview

Chronic migraine is defined as headache on 15 or more days a month for over three months, with migraine features on at least 8 of those days. It is the most disabling form of migraine and often develops gradually from episodic migraine. The good news is that with a structured preventive plan, many people revert to an episodic pattern. This page focuses on the chronic pattern; for migraine in general, see Migraine.

A key and reversible driver is medication overuse — taking acute painkillers or triptans on 10 or more days a month can itself transform episodic migraine into chronic daily headache. Recognising and correcting this is often the single most effective step.

How episodic migraine becomes chronic

• Frequent acute medication use (the most common and reversible factor).
• Untreated or undertreated migraine over years.
• Obesity, sleep disorders (especially sleep apnoea) and depression or anxiety.
• Caffeine overuse or withdrawal cycles.
• Hormonal fluctuations and stressful life events.

Evaluation

Beyond confirming the frequency, evaluation reviews the exact medication intake (often underestimated by patients), screens for sleep apnoea and mood disorders, checks blood pressure and excludes secondary causes. A careful medication history is central — bring all painkillers, including over-the-counter ones, to your visit.

Management

Management is stepped. First, acute medication overuse is identified and reduced with a structured plan. A preventive medicine is started and given an adequate trial (usually 2–3 months) at the right dose. Lifestyle measures — regular sleep, meals, hydration and trigger management — are essential. For people who do not respond to oral preventives, specialist treatments such as botulinum toxin injections or CGRP-targeted therapies may be considered via referral. The aim is to reduce headache days back toward an episodic pattern.

Follow-up

A daily headache diary is essential to track progress. Follow-up every few months reviews headache days, medication use and side effects, and steps up or adjusts treatment toward the goal of fewer than 10 headache days a month.

How we help

Dr. Nayak identifies the factors driving chronification — especially medication overuse — builds a preventive plan, and coordinates specialist referral when advanced therapies are appropriate. Sleep, mood and metabolic contributors are addressed alongside the headache itself. Consultations are available in-clinic in Bhubaneswar and over teleconsultation.
