Seeking neurologists to answer questions on how migraines affect the brain Seeking neurologists/MDs to answer questions about what exactly happens in our brains during a migraine. 1. Some people believe migraines are "just a headache." How do migraines differ from headaches in terms of what is happening in the brain? 2. Are you able to highlight specific areas of the brain that are affected during a migraine, and what is going on/happening in those areas during an attack? (Ex: hypothalamus, brainstem, cerebral cortex, pain matrix (Insula, ACC, Thalamus)? 3. During a migraine attack, the brain releases neurotransmitters that cause inflammation and vessel dilation. Can you explain how this happens? 4. Can you highlight some temporary brain changes/effects of migraines vs. longterm brain changes/effects of migraines?

I've spent nearly two decades at Harvard Medical School and MGH Pain Center working with chronic pain patients, many with debilitating migraines. While I'm not a neurologist, I've evaluated hundreds of migraine cases for life care planning and worked alongside neurologists to translate brain pathology into functional outcomes. The key difference between headaches and migraines is that migraines are a neurological disease involving cortical spreading depression--a wave of electrical silence that moves across the brain at 2-5mm per minute. This triggers the trigeminal nerve system, which releases CGRP (calcitonin gene-related peptide) and substance P, causing inflammation around blood vessels in the meninges. Regular headaches don't have this neurological cascade. The hypothalamus often activates first (which is why patients get food cravings or yawning before attacks), then the brainstem pain centers amplify signals, and finally the cortex processes this as severe pain while the thalamus acts as a relay station. During this process, serotonin drops sharply and glutamate floods synapses, creating that characteristic throbbing sensation. Short-term effects include temporary cognitive slowing and visual disturbances that resolve post-attack. Long-term, I've reviewed MRI studies in my cases showing white matter lesions and cortical thickness changes in chronic migraine patients--actual structural brain changes. One patient I evaluated had 20+ migraine days monthly for five years and showed measurable atrophy in pain-processing regions, which directly impacted her disability rating and future care costs in her personal injury case.

In my practice, I treat chronic migraine with Botox, and I hear "it's just a headache" all the time. Migraine is a brain state shift, not a sore scalp. The pain can start in deep control centers, then spread through sensory networks. A 2025 longitudinal fMRI study followed 12 people through 82 scans and showed brain connectivity changes across the migraine cycle, with patterns that shift during the attack and normalize after. During an attack, the trigeminal system releases CGRP and other signals. That drives vessel dilation and neurogenic inflammation. Your cortex can misfire too, which helps explain aura and sensory overload. A 2025 imaging paper linked insula subregion changes with migraine duration, frequency, and intensity. Long term, MRI white matter spots are reported more often in migraine with aura and in people with longer disease duration or higher attack frequency, though studies vary.
