Did you know that India has the highest number of migraine cases globally, with nearly 213.9 million people affected? According to a recent Global Burden of Disease study, migraines are most common among individuals in their 20s and 30s, as well as those from socioeconomically disadvantaged backgrounds.

However, migraines are far more than just severe headaches. They are a complex neurological condition that can cause intense, throbbing pain, often accompanied by nausea, vomiting, and sensitivity to light and sound. Migraines typically progress through different phases, from early warning signs (prodrome) to sensory disturbances (aura), the headache itself, and finally, the recovery phase (postdrome).

Interestingly, migraines don’t just exist in isolation. They are often linked to other neurological disorders, such as epilepsy, multiple sclerosis, and stroke, sharing common triggers and underlying mechanisms. This raises an important question—could migraines be a sign of a deeper neurological issue?

In this blog, we explore the connection between migraines and neurological disorders, uncovering potential links, shared causes, and why a comprehensive medical evaluation is essential for anyone experiencing frequent or severe migraines.

Understanding Migraines

What is a Migraine?

Migraines are characterised by recurrent episodes of moderate to severe headache pain, often described as throbbing or pulsating. They are a complex neurological disorder, not simply a severe headache. Migraines can be categorised into different types, including:

• Migraine with Aura: Characterised by visual, sensory, motor, or speech disturbances that precede or accompany the headache.
• Migraine without Aura: The most common type, characterised by headache without aura.
• Chronic Migraine: Headaches occurring on 15 or more days per month for more than three months, with at least eight of those days meeting the criteria for migraine.

Symptoms of Migraines

Beyond headaches, migraines can cause a wide range of symptoms, including:

• Nausea and Vomiting
• Sensitivity to Light (Photophobia)
• Sensitivity to Sound (Phonophobia)
• Visual Disturbances (Auras): Flashing lights, zig-zag lines, blurred vision
• Cognitive Difficulties: Difficulty concentrating, confusion
• Fatigue
• Dizziness

The Impact of Migraines

Migraines can significantly impact a person’s quality of life, whether it is the ability to work, attend school, or participate in social activities. Chronic migraines can lead to:

• Reduced Productivity: Frequent headaches can make it difficult to focus and perform tasks.
• Missed Work or School: Migraines are a common cause of absenteeism.
• Social Isolation: People with migraines may avoid social situations due to the fear of triggering a headache.
• Mental Health Issues: Migraines are often associated with anxiety, depression, and other mental health conditions.

Neurological Disorders and Their Connection to Migraines

Migraines are more than just severe headaches; they are complex neurological events that often intersect with other neurological disorders. Understanding these connections is crucial for accurate diagnosis and effective treatment. Below, we explore the links between migraines and three major neurological conditions: epilepsy, stroke, and multiple sclerosis (MS).

• Epilepsy and Migraine

Epilepsy is a neurological disorder marked by recurrent seizures due to abnormal electrical activity in the brain. Research indicates a strong link between epilepsy and migraines, with individuals often experiencing both conditions.

This connection may stem from shared genetic factors affecting neuronal excitability, cortical spreading depression (CSD) involved in migraine aura and seizures, and imbalances in neurotransmitters like GABA and glutamate. In rare instances, migraines can trigger seizures, a condition called migralepsy, which necessitates thorough medical assessment.

B. Stroke and Migraine

A stroke occurs when blood flow to the brain is disrupted, either due to a blockage (ischemic stroke) or bleeding (hemorrhagic stroke), resulting in brain damage. Migraines, particularly those with aura, are associated with a slightly elevated risk of ischemic stroke, especially in women.

This link may be explained by several mechanisms, including endothelial dysfunction, which can promote blood clot formation; the presence of a patent foramen ovale (PFO), a heart defect that may allow clots to reach the brain; and temporary changes in brain blood flow during migraines. Risk factors for stroke in migraine sufferers are heightened in women who smoke, use oral contraceptives, or have a history of cardiovascular disease.

C. Multiple Sclerosis (MS) and Migraine

Multiple sclerosis (MS) is a chronic autoimmune disorder that damages the central nervous system by causing inflammation and destruction of the myelin sheath, the protective layer around nerve fibers. Research indicates a higher prevalence of migraines among individuals with MS, potentially due to overlapping mechanisms such as brain and spinal cord inflammation, which may contribute to migraine development, and MS lesions in brain regions involved in pain processing, which could trigger migraines.

Additionally, shared genetic factors might predispose individuals to both conditions. Clinically, migraines in MS patients tend to be more severe and are often triggered by MS-related inflammation or brain lesions.

Given the complex interplay between migraines and other neurological conditions, it’s essential to highlight Dr. Vikas Gupta’s emphasis on comprehensive evaluation. He notes it by saying, “Patients must understand that migraines are frequently interconnected with other neurological conditions. Therefore, a comprehensive evaluation, considering all potential contributing factors, is essential for developing a personalised and effective treatment strategy.”

When to Seek Medical Evaluation

It’s important to seek medical evaluation if you experience any of the following:

• Sudden onset of severe headache (thunderclap headache)
• Headache accompanied by fever or stiff neck
• Headache with neurological deficits, such as weakness, numbness, or speech difficulties
• Changes in vision, such as double vision or vision loss
• Seizures
• A significant change in the pattern, frequency, or severity of your migraines
• New neurological symptoms developing alongside migraines

Diagnosis and Treatment

The diagnosis of migraines and associated neurological disorders typically involves a thorough medical history, physical examination, and neurological evaluation. Diagnostic tests may include:

• MRI (Magnetic Resonance Imaging): To visualise the brain and identify any structural abnormalities.
• CT Scan (Computed Tomography): To detect bleeding or other acute problems in the brain.
• EEG (Electroencephalogram): To measure brain electrical activity and detect seizures.
• Blood Tests: To rule out other medical conditions.

Treatment for migraines and associated neurological disorders depends on the specific underlying condition and may include:

• Medications:
  • Pain relievers: Over-the-counter or prescription pain relievers for acute migraine attacks.
  • Triptans: Medications that target serotonin receptors to relieve migraine pain.
  • Preventive medications: Medications taken regularly to reduce the frequency and severity of migraines (e.g., beta-blockers, tricyclic antidepressants, anti-seizure medications).
  • Medications for the associated neurological disorder: Specific medications to manage epilepsy, MS, stroke prevention, etc.

• Lifestyle Changes:
  • Stress management: Techniques to reduce stress, such as yoga, meditation, or deep breathing exercises.
  • Regular sleep schedule: Maintaining a consistent sleep-wake cycle.
  • Healthy diet: Avoiding trigger foods and maintaining a balanced diet.
  • Regular exercise: Engaging in regular physical activity.

• Other Therapies:
  • Physical therapy: For managing musculoskeletal pain and improving mobility.
  • Cognitive-behavioral therapy (CBT): To help manage pain, stress, and anxiety.
  • Biofeedback: To learn to control physiological responses, such as heart rate and muscle tension.

Conclusion

Migraines are a complex neurological condition that can significantly impact the quality of life. As explored, migraines are frequently associated with other neurological disorders such as epilepsy, multiple sclerosis, and stroke, highlighting the importance of a comprehensive approach to diagnosis and treatment.

Understanding the link between migraines and these conditions is the first step toward effective management. By identifying triggers and addressing the underlying health issues, you can take control of your migraines and reduce their impact on your daily life.

If you or a loved one suffers from migraines, don’t dismiss them as “just headaches.”
