Migraine and Headache
Migraine is a neurological condition that involves far more than head pain. Dizziness, visual sensitivity, brain fog, nausea, motion intolerance, and neck involvement are all part of the picture for many patients. These questions cover what migraine is, how it presents, what contributes to it, how it is evaluated, and how care is approached.
Understanding migraine
- What is migraine?Migraine is a neurological condition — not just a bad headache. It involves changes across pain, sensory, visual, vestibular, and autonomic pathways, and it usually presents in recurring episodes with characteristic patterns.
- Is migraine more than a headache?Yes. Head pain is only one feature. Migraine can involve dizziness, visual sensitivity, nausea, cognitive slowing, neck pain, fatigue, and difficulty tolerating normal activity — sometimes with little or no head pain at all.
- What is migraine with aura?Migraine with aura includes reversible neurological symptoms — most often visual, but sometimes sensory or language-related — that precede or accompany the attack.
- What Is Vestibular Migraine?Vestibular migraine is a form of migraine in which dizziness, motion sensitivity, and imbalance are the dominant symptoms, sometimes with little or no head pain.
- What is chronic migraine?Chronic migraine generally refers to a pattern of headaches on 15 or more days per month, at least eight of which have migraine features, over a period of three months or more.
- What is post-traumatic migraine?Post-traumatic migraine describes migraine features that develop or worsen after a head or neck injury — typically a concussion, whiplash, or auto accident.
- What is the difference between migraine and cervicogenic headache?Migraine is a neurological condition with sensory, visual, vestibular, and autonomic features. Cervicogenic headache originates from structures in the neck. The two often overlap, and one can trigger or amplify the other.
Symptoms
- Can migraine cause dizziness?Yes. Dizziness, unsteadiness, and motion sensitivity are common in migraine — and are the dominant feature of vestibular migraine.
- Can migraine cause brain fog?Yes. Slowed thinking, word-finding difficulty, and reduced focus are common before, during, and after migraine attacks — a well-recognized part of the migraine cycle.
- Why does migraine cause nausea?Nausea in migraine reflects involvement of the brainstem centers that regulate gastrointestinal function and autonomic responses. It is part of the neurological event, not a separate problem.
- Why do light, sound, movement, or screens trigger symptoms?Migraine biology involves heightened sensitivity across sensory systems. Light, sound, motion, and screens deliver a heavier neurological input load, which raises symptom levels or triggers episodes.
- Can migraine cause neck pain?Yes. Neck pain is one of the most common features of migraine — often present at the start or well before the head pain — because the trigeminal and cervical pathways share the same brainstem region.
- Can migraine affect balance?Yes. Even outside of vestibular migraine, many patients experience unsteadiness, motion intolerance, or reduced tolerance for busy visual environments as part of their pattern.
- Can migraine occur without severe head pain?Yes. Migraine can present with dizziness, brain fog, nausea, visual sensitivity, or fatigue as the dominant symptom, with only mild head pain or none at all — sometimes called 'silent' or 'atypical' migraine.
Causes and contributors
- Can neck dysfunction contribute to headache?Yes. The upper cervical spine shares neurological pathways with the trigeminal system that generates migraine, so neck dysfunction can contribute to and amplify migraine patterns.
- Can concussion trigger migraine?Yes. Concussion can initiate new migraine in people without prior history and can substantially worsen an existing pattern.
- How does sleep affect migraine?Sleep is one of the most powerful modifiers of the migraine threshold. Too little, too much, irregular timing, and poor sleep quality can each trigger or amplify migraine.
- Can skipped meals or blood-glucose changes trigger migraine?Yes. Blood-glucose swings and skipped meals are common migraine triggers, particularly when combined with other stressors on the system.
- Can autonomic dysfunction affect migraine?Yes. The autonomic nervous system is closely tied to migraine biology. Poor regulation of heart rate, blood pressure, and blood flow can amplify migraine frequency and severity.
- What is the migraine threshold?The migraine threshold is the level of neurological input a person can tolerate before symptoms are triggered. Anything that raises the load or lowers the threshold — sleep loss, blood sugar drops, dehydration, cervical dysfunction, sensory overload — makes episodes more likely.
- Why do multiple small triggers sometimes cause an attack?Because triggers add up. Any individual factor may sit below the threshold on its own, but combined they can push the total load past what the nervous system can currently tolerate.
Evaluation
- How is migraine evaluated?Evaluation combines a detailed history and headache pattern with a neurological examination and, when appropriate, testing of vestibular, oculomotor, cervical, autonomic, and cognitive contributors.
- Why evaluate eye movements and balance?Because migraine, concussion, and cervical dysfunction commonly disrupt the same vestibular and oculomotor pathways. Testing these systems identifies which are contributing to a patient's specific pattern.
- When is imaging necessary for headache?Imaging is generally reserved for headaches that are new, sudden, worst-ever, associated with neurological changes, or accompanied by other red flags. Routine migraine does not require imaging.
- When should headache be considered an emergency?Any sudden, severe, or unusual headache — especially with neurological symptoms — should be treated as an emergency. When in doubt, seek immediate medical evaluation.
- How do you distinguish migraine from post-concussion symptoms?The two overlap significantly and often coexist. Careful history, examination, and testing help identify how much of the picture is migraine biology versus other post-concussion system involvement.
Treatment and recovery
- Can cervical care help some headache patients?Yes. When cervical dysfunction is contributing to headache, targeted care of the neck often reduces headache burden — sometimes substantially. It is not a treatment for migraine itself.
- What is vestibular rehabilitation?Vestibular rehabilitation is a structured, exercise-based approach to training the balance and eye-movement systems so they tolerate more input with fewer symptoms.
- Can exercise help migraine?Yes. Structured, gradually progressed aerobic exercise raises migraine threshold for many patients. Pushing too hard too fast can trigger attacks, so pacing and progression matter.
- How should activity be progressed?Activity is progressed by staying below the current symptom threshold long enough to consolidate the gain, then increasing incrementally. Random pushing and complete rest are both usually counterproductive.
- What lifestyle factors may affect migraine frequency?Sleep, meal timing, hydration, physical activity, stress load, and screen use are among the most impactful lifestyle factors on migraine frequency. None of them are a cure — but each shifts the threshold.
- When should a neurologist be involved?Neurology involvement is appropriate when a diagnosis is unclear, when features suggest something other than migraine, when management is not producing adequate results, or when specialty medical therapies are indicated.
