Migraine involves more than head pain. Use this lesson and the expanded homepage notes to separate a biological explanation, a person’s experience and the limits of a teaching model.

More than head pain
Migraine is a neurological disorder involving interactions among nerve activity, chemical signals, and blood vessels. An attack can involve head pain, nausea, fatigue, and sensitivity to light or sound. A person’s experience can vary between attacks, and different people can have different patterns.
Some people experience an aura, which can involve temporary changes in vision or other sensations. Many people with migraine do not experience aura. It is therefore misleading to use one symptom, or one animation of an attack, as a description of everyone with migraine.
Separate the model from the experience
A teaching animation can use color, arrows, and exaggerated scale to make signals easier to follow. Those visual choices do not show what a particular person’s brain looks like or prove what is causing their symptoms. “A signal is being illustrated” describes the model; “a person feels sensitivity to light” describes a possible experience.
A trigger is a factor that may influence when an attack occurs; it is not a complete explanation of the disorder. Patterns vary between people. For example, an association with a change in sleep does not mean that one sleep pattern causes every person’s migraine. This lesson cannot identify the cause of an individual headache or choose treatment.
Key concepts
- Neurological disorder
- A condition involving the nervous system. Calling migraine only a headache leaves out its wider sensory and other possible effects.
- Aura
- Temporary neurological symptoms, often visual, that some people experience with migraine. Aura is not part of every attack.
- Model limitation
- A boundary on what a representation can show. An animation illustrates selected processes; it is not a scan or diagnostic test.
Check your understanding
Take 3–5 minutes independently. Write an explanation in your own words or sketch a labelled model on paper before opening each answer. These are original practice prompts; nothing is submitted or graded.
Why does the phrase “just a headache” leave out important parts of migraine?
Show reasoning
Migraine can include sensory changes, nausea and fatigue as well as head pain. These features involve more of the person’s experience than the location or strength of pain alone.
One learner says aura must occur during every migraine attack. How would you revise the claim?
Show reasoning
Some people experience aura, but many attacks occur without it. A lesson should describe possible patterns without treating one pattern as universal.
Compare “the animation shows a bright arrow” with “the person reports light sensitivity.” What does each statement tell us?
Show reasoning
The first describes a visual choice used to represent a process. The second describes a reported experience. The arrow does not establish what is happening in that individual or explain all possible causes of the symptom.
