Chronic Migraine: Causes and Treatments
Migraines are more than just headaches; they are complex neurological events that can significantly impair one's quality of life. Chronic migraines, in particular, are especially debilitating, affecting millions worldwide. Know the causes, symptoms, types and treatments associated with chronic migraines, providing a comprehensive understanding of this intricate condition.
What is Chronic Migraine?
Chronic migraine is defined as experiencing headaches on 15 or more days per month for at least three months, with at least eight of those headaches having migrainous features. This condition is classified under the International Classification of Headache Disorders with its specific coding, known as chronic migraine ICD 10. Unlike episodic migraines, chronic migraines occur with much greater frequency, often leading to significant distress and disability.

Get A Second OpinionEpisodic vs. Chronic Migraine
Chronic migraine and episodic migraine have the same symptoms. The key difference is the timing.
- You have episodic migraine if your headaches occur up to 14 days in a month.
- Chronic migraine means you have 15 or more headache days a month, including at least 8 days of migraine symptoms.
Another real difference is chronic migraine tend to be more serious than episodic.
- Chronic migraine can revert to episodic migraine, and episodic migraine can develop into chronic migraine. Research indicates 2.5% of people with episodic migraine progressed to chronic migraine over a year, and a more recent study showed 26% of people with chronic migraine reverted to episodic migraine over 2 years.
Chronic Migraine Types
Chronic migraines can be divided into several types, primarily based on the presence or absence of aura. Understanding the stages of migraines can help individuals manage symptoms effectively. These stages are:
- Prodrome (Early Warning Phase): This stage can begin hours or even days before the headache itself. Symptoms include mood swings, food cravings, neck stiffness, fatigue or difficulty concentrating. If these early signs are recognized, it will prevent an all out attack.
- Chronic Migraine with Aura: This type involves neurological disturbances that precede the headache phase, such as visual disturbances, sensory changes, or speech difficulties.
- Chronic Migraine without Aura: More common and is characterized by headaches without preceding neurological symptoms. This type is also classified under chronic migraine without aura ICD 10.
- Attack (Headache Phase): The headache phase lasts from 4 hours up to several days. Symptoms include debilitating throbbing or pulsating pain, usually on one side of the head, sensitivity to light or sound, nausea and vomiting. This is usually the most debilitating stage of a migraine.
- Post-Drome (Recovery Phase): After the headache has passed, the post-drome phase can leave people feeling drained, confused or moody for up to a day. Some call it a “migraine hangover.”
Impact of Chronic Migraine
Chronic migraines significantly impact daily life, affecting physical health, emotional well-being, and social relationships.
- Reduced Work Productivity
- Emotional Strain
- Strained Relationships
- Physical Health Challenges
Chronic Migraine Symptoms
Common Chronic migraine symptoms can vary widely among individuals but often include the following:
- Intense Pulsating Headache: Often unilateral, though it can occur on both sides of the head.
- Nausea and Vomiting: Frequently accompany the headache, adding to the individual's discomfort.
- Sensitivity to Light and Sound: Known as photophobia and phonophobia, these symptoms are common during migraine attacks.
- Visual Disturbances: Particularly for those experiencing migraines with aura, visual symptoms may include flashing lights or blind spots.
- Increased Pain with Physical Activity: Physical exertion often exacerbates migraine pain.
Chronic migraines consist of a range of symptoms that appear in distinct phases:
- Prodrome: mood swings, food cravings, fatigue, neck stiffness announce the arrival of a migraine.
- Aura: Sensory disturbances such as flashes of light, blind spots or tingling in the hands and face usually occur before the headache.
- Attack: A stage marked by intense, pulsating pain, usually on one side of the head. Symptoms can consist of nausea, vomiting and sensitivity to light or sound.
- Post-Drome: Once the headache fades, some people experience lingering fatigue, confusion and mood changes, lasting for up to a day.
Chronic Migraine Causes
The exact chronic migraine causes remains elusive; however, several factors are believed to contribute to their development. These include:
Genetic Predisposition
There is a significant genetic component to migraines, with many sufferers reporting a family history of the condition. Genetic variations may affect neurotransmitter pathways, making individuals more susceptible to chronic migraines.
Environmental Triggers
Environmental factors such as changes in weather, exposure to bright lights, strong smells, or loud noises can trigger migraine attacks. Identifying and avoiding these triggers is crucial in managing chronic migraines.
Lifestyle Factors
Poor sleep habits, high levels of stress, and irregular eating patterns can increase the frequency of migraine attacks. Moreover, excessive caffeine consumption and alcohol intake have been linked to the exacerbation of migraine symptoms.
Triggers of Chronic Migraine
There are many factors that may trigger chronic migraines, including factors that upset the chemical balance of the brain and make episodes of migraines more likely. Recognising and avoiding these triggers is critical in controlling the condition.
Common triggers of Chronic Migraine include:
- Emotional stress
- Hormonal Changes
- Dietary Factors
- Irregular Sleep Issues
- Environmental Triggers
- Weather Changes
Effects of Chronic Migraines
Chronic daily migraines are more than just headaches—they are a disabling condition that affects nearly every aspect of life. For individuals experiencing migraines 15 or more days per month, the physical, emotional, and social effects can be profound.
Physical Effects:
- Chronic pain interferes with sleep, appetite and energy.
- Light, sound and smells can all feel overwhelming, making everyday activities difficult.
- People who have frequent migraines are at greater risk for other health issues, including anxiety, depression or medication overuse headaches.
Emotional and Psychological Effects:
- People who have chronic daily migraines can experience emotional distress as they may feel frustrated or hopeless about their condition.
- The unpredictability of when a migraine attack will happen can cause anxiety or fear about missing important events.
- It’s perfectly normal, depression is common because living with chronic pain and limitations can take a toll on your mental wellbeing in the long haul.
Social and Professional Effects:
- People with migraines have difficulty with work productivity, resulting in presenteeism or absenteeism.
- Social withdrawal can take a toll on relationships with friends and family.
- Being home-exiled by chronic daily migraine only enhances loneliness and lowers quality of life.
Chronic Migraine Diagnosis
Diagnosing chronic migraine involves a comprehensive assessment by a healthcare professional, often a neurologist. The diagnostic process typically includes:
- Medical History Review: A thorough review of the patient's headache history, including frequency, duration, and associated symptoms.
- Physical and Neurological Examination: To rule out other potential causes of chronic headaches.
- Imaging Tests: Such as MRI or CT scans, may be conducted to exclude other neurological disorders.
It's important for patients to keep a headache diary, documenting the frequency, duration, and characteristics of their headaches, as well as any potential triggers or patterns.
Chronic Migraine Treatment
Chronic Migraine Treatment requires a multifaceted approach, combining pharmacological and non-pharmacological strategies.
Pharmacological Treatments
- Chronic Migraine Medications: These are taken daily to reduce the frequency and severity of migraine attacks. Common classes include beta-blockers, anticonvulsants, and antidepressants.
- Acute Treatments: Medications such as triptans or nonsteroidal anti-inflammatory drugs (NSAIDs) are used during migraine attacks to alleviate symptoms.
- Botulinum Toxin Injections: Approved for chronic migraine treatment, Botox injections can reduce the frequency of headaches in some patients.
Non-Pharmacological Treatments
- Cognitive Behavioral Therapy (CBT): Aims to change negative thought patterns and behaviors that may exacerbate chronic pain.
- Lifestyle Modifications: Regular exercise, adequate hydration, and a balanced diet can help manage migraine symptoms. Stress management techniques, such as yoga or meditation, may also be beneficial.
- Supplementary Therapies: Some individuals find relief through acupuncture, biofeedback, or chiropractic care.
