Nearly 40 million Americans live with migraines, making it one of the most common neurological disorders in the country. Yet doctors say it remains one of the most misunderstood. Many patients spend years seeking a diagnosis because migraines can appear in ways that go far beyond severe headaches.
“The general concept about migraine in the common population is that it’s a headache syndrome,” said Dr. Hamid S. Hamdi, neurologist and director of the Headache Clinic at UTHealth Houston Neurosciences in Sugar Land, Texas. “People don’t know about all the other symptoms that migraine can cause, so they’re very surprised in the beginning.”
Migraines can begin days before the pain sets in, with early warning signs such as fatigue, irritability, neck discomfort, and food cravings. Many patients report intense desires for salty snacks, sweets, or chocolate. While chocolate was once blamed for triggering migraines, Hamdi said research now shows it’s usually the craving itself that signals the onset of an attack, likely linked to metabolic changes in the body.
About one in five migraine sufferers experience visual disturbances before or during an episode. Dr. Thomas Bravo, director of the Headache Center at Loma Linda University Health in California, said these visual auras can include shimmering lights, zig-zag lines, or temporary blindness. “It can be disturbing to a patient if it’s the first time,” he said. “But once they know it’s linked to their migraine and will pass, it becomes less frightening.”
Other patients face speech difficulties that can mimic a stroke. Bravo explained that temporary language impairment, known as aphasia, is a well-known but alarming symptom. “We see this all the time in the emergency department,” he said. “We make sure it’s not something like a stroke before diagnosing it as migraine-related.”
Sensitivity to light, sound, and smell is another hallmark feature. Dr. Brian Gerhardstein of the JFK Neuroscience Institute in New Jersey said some people also experience tactile allodynia, where even gentle touches like brushing hair or feeling a breeze can cause pain.
More severe forms, such as hemiplegic migraines, can lead to one-sided weakness or paralysis, closely resembling a stroke. “It can look exactly like a stroke, so a lot of these patients end up in the emergency room,” Gerhardstein said.
Children may experience abdominal migraines, which cause nausea, vomiting, and severe stomach pain without a headache. Doctors believe these symptoms are linked to the gut-brain connection.
Experts say migraines are more common in women, likely influenced by hormonal and genetic factors. Treatments now range from targeted medications to nerve-stimulation devices. Bravo noted that while occasional sufferers can rely on quick-relief drugs, those with frequent attacks may need daily preventive therapy. “It comes down to how disabling the attacks are and how much they affect a person’s life,” he said.
