, it often affects one side of the head and can be extremely painful, throbbing, or pulsating. It frequently comes with high sensitivity to light and sound and nausea and vomiting.
The research team used ultra-high-field 7T MRI to study the link between migraine and enlarged perivascular spaces. They also compared the scans to see how different types of migraine lead to structural microvascular changes. The results of the analysis revealed that the number of enlarged perivascular spaces in the centrum semiovale, the central area of white matter, was significantly higher in patients with migraine than in healthy controls. Plus, the quantity of enlarged perivascular space in the centrum semiovale was associated with deep white matter hyperintensity severity in migraine patients.
"Although we didn't find any significant changes in the severity of white matter lesions in patients with and without migraine, these white matter lesions were significantly linked to the presence of enlarged perivascular spaces. This suggests that changes in perivascular spaces could lead to the future development of more white matter lesions."
