Migraine is a common neurological disorder. It is characterized by intense headaches. These headaches are often pulsating. They usually affect one side of the head. Migraine is accompanied by other symptoms. These include nausea, vomiting, and increased sensitivity to light and sound. Migraine attacks can be very disabling. They significantly impact the quality of life for affected individuals. Understanding migraine, its causes, and its mechanisms is essential. This allows for better disease management and effective relief.

What is Migraine?

Migraine is a chronic neurological disease. It affects approximately 1 in 7 people worldwide. It is not limited to a simple headache. Migraine is a set of symptoms. These symptoms manifest in distinct phases. A typical migraine attack can last from a few hours to several days. It greatly impacts daily activities.

Doctors distinguish several types of migraine. Migraine without aura is the most frequent form. It is not preceded by any specific neurological signs. Migraine with aura, on the other hand, is preceded by visual, sensory, or verbal symptoms. These auras appear one hour before the pain. They usually disappear when the pain begins.

Causes and Risk Factors of Migraine

The exact causes of migraine are not fully understood. Researchers believe they involve a combination of genetic and environmental factors. The brains of people with migraine react differently to certain stimuli. This responsiveness is often heightened.

Several elements promote the onset of an attack. These are called “triggers.” They vary from person to person. Common risk factors and triggers include:

• Genetic Factors: Migraine often runs in families. Having an affected parent increases the risk.
• Hormonal Changes: Hormone fluctuations (menstrual cycle, pregnancy, menopause) trigger migraines. Women are more frequently affected.
• Stress: Physical or emotional stress can provoke attacks.
• Foods and Drinks: Certain foods (chocolate, aged cheeses), caffeine, or alcohol (red wine) are triggers.
• Lack of Sleep or Excess Sleep: Irregular sleep disrupts the body’s balance.
• Weather Changes: Variations in atmospheric pressure or temperature influence migraine.
• Sensory Stimuli: Intense lights, loud noises, or strong odors trigger attacks.
• Dehydration: Insufficient water intake causes headaches.

Identifying one’s own triggers is an important step. This helps better manage migraine.

Symptoms and Signs of Migraine

Migraine manifests with a variety of symptoms. Pain is the main symptom. It is often described as pulsating and intense. It usually affects one side of the head. This pain worsens with physical activity.

However, a migraine attack goes beyond a simple headache. Other signs frequently accompany the pain:

• Nausea and Vomiting: These digestive symptoms are very common.
• Phonophobia: Noise becomes unbearable.
• Photophobia: Light, even faint, causes intense pain.
• Osmophobia: Certain odors become intolerable.
• Auras: Approximately 25% of people with migraine experience an aura. These are transient disturbances. They can be visual (scintillating points, zigzag lines, partial vision loss), sensory (numbness, tingling), or language-related (difficulty finding words). They usually last 5 to 60 minutes. They precede the pain.
• Fatigue and Irritability: These symptoms often occur before the attack.
• Difficulty Concentrating: Cognitive functions can be impaired.

The post-attack phase, called the resolution phase, is characterized by fatigue. Concentration difficulties may persist.

Diagnosis: How is Migraine Detected?

The diagnosis of migraine mainly relies on medical history. The doctor questions the person about their symptoms. They ask about the frequency of attacks. They inquire about the duration and intensity of the headaches. Associated symptoms such as nausea, sensitivity to light, or noise guide the diagnosis.

A neurological examination is often performed. It helps the doctor rule out other causes. No specific blood test or brain imaging diagnoses migraine. However, the doctor may request additional tests. This happens to exclude other pathologies. For example, a CT scan or magnetic resonance imaging (MRI) may be necessary. These eliminate more serious conditions. A headache diary can be useful. It helps identify triggers. It allows tracking the response to treatments.

Treatments and Management of Migraine

The management of migraine is twofold. It aims to relieve pain during attacks. It also seeks to reduce their frequency and intensity. The most appropriate treatment depends on the person. It also depends on the severity and frequency of the migraine.

Acute treatments (to relieve attacks):

• Over-the-counter analgesics: Some medications like ibuprofen or acetaminophen may be sufficient for mild migraines.
• Triptans: Triptans are specific medications. They act on serotonin receptors. They constrict cerebral blood vessels. This reduces pain and associated symptoms.
• Gepants and Ditans: These new classes of drugs offer an alternative. They target other neurological mechanisms.
• Anti-nausea medications: They relieve nausea and vomiting.

Preventive treatments (to reduce the frequency of attacks):

• Beta-blockers: Initially used for hypertension.
• Tricyclic antidepressants: They have a beneficial effect in migraine prevention.
• Antiepileptics: Certain anticonvulsants reduce the frequency of attacks.
• CGRP Blockers: Monoclonal antibodies targeting calcitonin gene-related peptide (CGRP) are revolutionizing migraine prevention. They are administered by injection.
• Botulinum toxin (Botox) injections: They are effective for chronic migraines (more than 15 days per month).

Non-pharmacological approaches complement these treatments. Good stress management and lifestyle changes are essential. Complementary therapies, such as acupuncture, are sometimes used. Always consult a healthcare professional. They will establish the most suitable treatment plan.

Recent Scientific Advances in Migraine

Migraine research is very active. It aims to better understand the pathophysiology of the disease. It seeks to develop new therapeutic options. Several significant advances occurred between late 2024 and mid-2025.

Firstly, recent studies confirm the effectiveness of anti-CGRP monoclonal antibodies. These drugs block the action of a key protein in the transmission of migraine pain. New data shows a lasting improvement in quality of life. They significantly reduce the frequency and intensity of attacks. These studies support their first-line use for chronic migraine prevention.

Secondly, researchers are increasingly interested in oral gepants. These small molecules also block CGRP receptors. Final clinical trials reveal their effectiveness for acute treatment of migraine attacks. Their safety profile is favorable. They offer an alternative for people who do not respond to triptans or have contraindications. Some gepants are also exploring their potential as daily preventive treatment.

Finally, research is exploring the modulation of nerve stimulation. Non-invasive devices apply electrical or magnetic stimulation. They target specific nerves, such as the vagus nerve or the trigeminal nerve. Recent studies show promising results. These devices help reduce the frequency of migraines. They also act on the intensity of attacks. They offer a non-pharmacological option for prevention and treatment.

Prevention: Is it possible to reduce the risk of Migraine?

Migraine prevention is essential. It reduces the frequency, intensity, and duration of attacks. Adopting certain lifestyle habits helps considerably. An effective prevention plan often combines lifestyle changes. It may include medication. Always discuss options with a doctor.

Here are common prevention strategies:

• Identify and avoid triggers: Keeping a diary helps identify triggers. Then avoid them as much as possible.
• Maintain a regular sleep routine: Go to bed and wake up at fixed times. This includes weekends.
• Manage stress: Relaxation techniques (meditation, yoga, deep breathing) reduce stress levels.
• Adopt a balanced diet: Avoid skipping meals. Maintain adequate hydration.
• Engage in regular physical activity: Moderate and regular exercise improves overall health. It can also reduce the frequency of migraines. Always start slowly.
• Limit caffeine and alcohol consumption: These substances trigger migraines in some people.
• Preventive medication: If migraines are frequent or disabling, the doctor may prescribe daily medication. They reduce the number or severity of attacks (see Treatments section).

Migraine prevention is an ongoing process. It sometimes requires adjustments.

Living with Migraine

Living with chronic migraine presents a significant challenge. This disease impacts not only physical health. It also affects the emotional and social spheres. Adopting coping strategies and seeking support is essential. This allows for better management of attacks and maintaining a good quality of life.

Here are some tips for living with migraine:

• Establish a crisis management plan: Work with your doctor. Define a clear action protocol. Include when to take medication and what comfort measures to apply.
• Communicate about the illness: Inform your professional and personal circle. They will better understand your situation. This facilitates adapting your environment.
• Join a support group: Sharing experiences with other people with migraine offers valuable support. It can also provide practical tips.
• Take care of your mental health: Chronic migraine can lead to stress, anxiety, and even depression. Consulting a psychologist or therapist helps you. They will provide tools to manage these aspects.
• Arrange your environment: Reduce bright lights. Avoid loud noises. Create a calm and dark space during attacks.
• Do not hesitate to rest: During an attack, rest is often the best option. Listen to your body.

Adopting a proactive approach to migraine helps improve the quality of life.
