What is a migraine?

Migraine is more than a typical headache: it is a neurologic disorder involving changes in brain chemistry and blood vessel activity that produce throbbing, often one-sided pain and sensitivity to light or sound. Many people experience an aura — transient sensory or visual symptoms — that precede pain. Acute attacks vary in duration and intensity; some resolve with over-the-counter medications while others require prescription therapy. Accurate diagnosis often depends on a pattern of recurrent episodes and associated symptoms rather than a single event.

How is a headache different from a migraine?

Headache is a general term describing pain anywhere in the head, while migraine is a specific type with characteristic features: moderate-to-severe pulsatile pain, activity-related worsening, nausea, and sensory sensitivities. Tension-type headaches tend to be milder and more bilateral. Identifying migraine triggers, frequency, and disability helps clinicians choose between short-term relief and preventive strategies. Tracking attacks in a diary or app can distinguish occasional headaches from chronic migraine and guide appropriate treatment choices.

Why does vision change during migraine?

Visual changes in migraine often result from cortical spreading depression and altered neural signaling in visual pathways, producing shimmering lights, zigzag lines, blind spots, or tunnel-like vision. These symptoms—collectively called aura—typically develop over minutes and last less than an hour. Visual aura is usually reversible, but sudden or persistent vision loss requires urgent evaluation to rule out other causes. Discuss any new or atypical visual symptoms with a healthcare provider or eye specialist to ensure proper assessment.

Can a migraine affect the eye?

Migraines can produce eye-related symptoms, including eye pain, eye redness, tearing, and transient visual disturbances. A subtype called retinal or ocular migraine can cause brief, usually reversible monocular vision loss or visual scotomas; it is uncommon but clinically important to evaluate. An ophthalmologic exam helps rule out eye disease such as retinal detachment, optic neuritis, or vascular issues. If eye symptoms occur with headaches, a coordinated approach between primary care, neurology, and ophthalmology ensures safe diagnosis and treatment.

Which health steps reduce migraine risk?

Lifestyle and self-care form a cornerstone of migraine management. Regular sleep, consistent meals, hydration, caffeine moderation, and targeted exercise can reduce attack frequency. Stress management techniques—such as cognitive behavioral therapy, biofeedback, or relaxation training—are evidence-based adjuncts for some patients. Avoiding known triggers (food, strong odors, irregular schedules) helps but may not eliminate attacks. Preventive medications or procedures are considered when headaches are frequent or disabling despite lifestyle adjustments.

Treatment approaches and when to seek specialty care

Acute treatments include nonprescription analgesics (acetaminophen, NSAIDs) and prescription options such as triptans or combination agents that address pain and associated symptoms. Antiemetics may relieve nausea. For frequent or severe migraine, preventive medications (beta blockers, certain antiepileptics, some antidepressants) or newer targeted therapies such as CGRP pathway inhibitors are options. For chronic migraine, onabotulinumtoxinA injections and selected neuromodulation techniques may be offered. Referral to a neurologist or headache specialist is appropriate for diagnostic uncertainty, progressive vision symptoms, poor response to treatment, or when advanced therapies are being considered.

Conclusion

Migraine treatment combines accurate diagnosis, individualized acute therapy, preventive strategies when needed, and attention to vision and eye symptoms. Nonpharmacologic measures—sleep hygiene, hydration, trigger management, and stress reduction—are valuable complements to medications. Because migraine presentations vary, coordination with primary care, neurology, and ophthalmology can improve safety and outcomes.
