BIMARIDUR HEALTH ENCYCLOPEDIA

Migraine

Migraine is a neurological disorder characterized by recurrent attacks that may cause moderate to severe headache, often with nausea and sensitivity to light or sound. Some people experience aura before or during an attack.

ICDG43
Affected areaBrain and nervous system, with symptoms commonly involving the head, eyes, gastrointestinal system and sensory processing pathways
ContagiousnessNot contagious and cannot spread from person to person.
01 • QUICK UNDERSTANDING

What is Migraine?

Migraine is a neurological condition involving recurrent attacks of headache and associated symptoms. Attacks may occur with or without aura and can last for hours to several days. Migraine is more than an ordinary headache and can substantially affect daily activities.

02 • BODY & MECHANISM

What happens in the body?

Body structure involved

Migraine involves functional networks of the brain and nervous system rather than a structural lesion in most patients. Trigeminal sensory pathways and brain regions involved in pain and sensory processing play important roles.

How it starts

Migraine attacks can be influenced by genetic susceptibility and environmental or physiological triggers. Brain and sensory pathways become abnormally activated, producing headache and associated symptoms.

What happens inside the body

Migraine involves abnormal activation of brain and sensory pathways. Changes in neuronal signaling and trigeminal pathways can contribute to pain and associated symptoms such as nausea and sensitivity to light and sound.

03 • TYPES & CLASSIFICATION

Types and classification

Migraine can be classified as migraine without aura or migraine with aura. Other clinically relevant distinctions include episodic versus chronic migraine and attacks with or without status migrainosus.

Major clinical types include migraine without aura, migraine with aura and chronic migraine. Aura may involve visual, sensory or speech symptoms. Migraine can also occur in children and adolescents with age-specific presentations.

04 • SYMPTOMS

Symptoms and warning signs

Moderate to severe headache

Throbbing or pulsating head pain

Nausea

Vomiting

Sensitivity to light

Sensitivity to sound

Sensitivity to smells

Pain worsened by routine physical activity

Visual aura such as flashing lights or zigzag lines

Numbness or tingling during aura

Difficulty speaking during aura

Fatigue or difficulty concentrating after an attack

Neck discomfort

05 • LESS OBVIOUS SIGNS

Signs that may be easy to miss

Migraine may include fatigue, mood changes, food cravings, yawning, neck discomfort or difficulty concentrating before the headache begins. These early symptoms can occur during the prodrome phase.

06 • CAUSES

What can cause this disease?

Migraine has a strong genetic and neurological basis. Attacks can be influenced by triggers such as sleep disruption, skipped meals, dehydration, stress, hormonal changes and individual sensory or environmental factors.

07 • RISK FACTORS

Who may have a higher risk?

1

Family history of migraine

2

Female sex

3

Hormonal fluctuations

4

History of migraine beginning in childhood or adolescence

5

Irregular sleep schedule

6

Skipped meals

7

Dehydration

8

High stress or major changes in stress

9

Frequent use of acute headache medicines

10

Certain individual foods, drinks or sensory triggers

08 • DIAGNOSIS

How is Migraine diagnosed?

Diagnosis is based mainly on headache characteristics, associated symptoms, attack duration, frequency, medical history and neurological examination. Imaging is considered when symptoms suggest another neurological condition.

Clinical evaluation

Recurrent characteristic headache attacks

Throbbing or pulsating headache

Nausea or vomiting

Light sensitivity

Sound sensitivity

Pain aggravated by routine activity

Typical aura symptoms when present

Normal neurological examination between attacks in many patients

Increasing headache frequency or change in usual pattern

Medication overuse

Laboratory tests

No routine laboratory test is required to diagnose typical migraine

Complete blood count when another condition is suspected

Electrolytes and metabolic tests when clinically indicated

Pregnancy testing when relevant to medication or diagnostic decisions

Inflammatory markers when a secondary headache disorder is suspected

Other targeted blood testing based on clinical findings

Imaging and scans

MRI brain when clinically indicated

CT head for selected acute or emergency presentations

CT angiography or MR angiography for selected vascular concerns

MR venography or other vascular imaging for selected indications

Spinal imaging only when symptoms suggest a spinal or secondary cause

Special or confirmatory tests

Detailed headache history and headache diary

Complete neurological examination

Assessment for migraine aura characteristics

Assessment for medication-overuse headache

Specialist headache evaluation for difficult or atypical cases

Lumbar puncture only when a specific secondary cause is suspected and clinically appropriate

09 • DIFFERENTIAL CONTEXT

Conditions that may look similar

Tension-type headache

Cluster headache

Medication-overuse headache

Sinus-related headache or facial pain

Cervicogenic headache

Stroke or transient ischemic attack

Meningitis or encephalitis

Brain tumor or other intracranial disorder

10 • EXTENT / STAGE

Stages or severity

Migraine attacks may occur in phases: prodrome, aura in some people, headache and postdrome. Not every person experiences every phase, and the duration and symptoms can vary between attacks.

Important:

Staging or grading systems differ between diseases. The information here is educational and should be interpreted by a qualified healthcare professional in the context of the individual case.

11 • TREATMENT

How is Migraine treated?

Treatment includes acute medicines to stop or reduce an attack and preventive strategies to reduce future attacks. Options can include appropriate over-the-counter or prescription medicines, triptans, CGRP-targeting therapies, preventive medicines and selected non-drug approaches.

Medicines that may be used

Acetaminophen or appropriate nonsteroidal anti-inflammatory drugs for selected acute attacks

Triptans for appropriate migraine attacks

CGRP-targeting medicines for acute or preventive treatment depending on the specific medicine

Preventive medicines selected according to migraine frequency and patient factors

Antiemetic medicines for significant nausea or vomiting

OnabotulinumtoxinA for selected chronic migraine patients

Other individualized acute or preventive therapies

Medicine safety:

Medicines listed here are for educational information only. Do not start, stop, or change a medicine without professional medical advice.

12 • COMPLICATIONS

Possible complications

Possible complications include prolonged attacks, medication-overuse headache, significant disruption of work or school, dehydration from repeated vomiting and, rarely, migraine-associated neurological complications. Some symptoms require urgent evaluation because they can resemble stroke or other serious conditions.

URGENT SAFETY INFORMATION

When should urgent medical help be considered?

Sudden thunderclap headache reaching maximum intensity within seconds or minutes

New weakness, numbness, facial drooping or difficulty speaking

New confusion, seizure or loss of consciousness

Severe headache with fever and stiff neck

New severe headache after significant head injury

A first or unusually severe headache with major neurological symptoms

Rapidly worsening or substantially changed headache pattern

Severe headache with persistent vomiting or other signs of serious illness

If symptoms are severe, rapidly worsening, or life-threatening, seek emergency medical care immediately.

13 • OUTLOOK

Prognosis and recovery outlook

Migraine can be recurrent and disabling, but many people achieve meaningful improvement with individualized treatment. Attack frequency and severity can change over a person's lifetime.

How to interpret these statistics

Survival statistics describe outcomes in groups of people and cannot predict exactly what will happen to one individual. Prognosis depends on factors such as cancer stage, tumor biology, treatment response, overall health, and follow-up.

14 • EPIDEMIOLOGY

How common is it?

Migraine is a common neurological disorder affecting people worldwide. It can occur in children, adolescents and adults and is more frequently reported in women.

15 • PREVENTION

Risk reduction and prevention

Prevention includes regular sleep, meals, hydration and exercise, trigger identification, stress management and avoiding medication overuse. Preventive medicines or procedures may be considered when clinically appropriate.
