What causes migraines? Study of ‘brain blackout’ offers clues

Migraines are a common and debilitating type of headache that affects millions of people worldwide. Despite their prevalence, the exact cause of migraines remains somewhat of a mystery. However, a recent study focusing on what researchers have dubbed ‘brain blackout’ has offered new insights into the origins of these severe headaches.

The study, led by a team of researchers from Harvard Medical School and published in the journal Science Advances, looked at the activity of the brain during migraines using a cutting-edge imaging technique called functional near-infrared spectroscopy (fNIRS). This technology allows scientists to monitor changes in blood flow and oxygen levels in the brain in real-time, providing valuable information about brain activity during a migraine attack.

What the researchers found was that during a migraine episode, certain areas of the brain experience a temporary ‘blackout’ or decrease in activity. This decrease in activity was most pronounced in the regions of the brain responsible for processing pain and sensory information, as well as areas involved in regulating emotions and stress responses.

These findings suggest that migraines may be caused by a disruption in the normal functioning of the brain, specifically in how it processes and responds to pain signals. The ‘brain blackout’ observed in this study could be a key factor in triggering the intense pain and other symptoms associated with migraines.

While more research is needed to fully understand the mechanisms behind migraines, this study offers important insights into the potential causes of these debilitating headaches. By identifying how the brain responds during a migraine attack, researchers may be able to develop more effective treatments and interventions for individuals suffering from migraines.

In the meantime, if you suffer from migraines, it is important to work with your healthcare provider to find a treatment plan that works for you. This may include medications, lifestyle changes, and stress management techniques to help reduce the frequency and severity of your migraine attacks. By staying informed and proactive about your migraine treatment, you can better manage your symptoms and improve your quality of life.
