Magnetic resonance imaging (MRI) detected parenchymal brain lesions in nearly half of migraine patients. These findings suggest MRI is crucial for diagnosing and evaluating migraine-associated brain changes.

Area of Science:

  • Neurology
  • Radiology
  • Neuroimaging

Background:

  • Migraine is a common neurological disorder.
  • Parenchymal brain lesions can be associated with migraine, but their prevalence and characteristics require further investigation.
  • Magnetic resonance imaging (MRI) offers detailed visualization of brain structures.

Purpose of the Study:

  • To evaluate the presence and nature of parenchymal brain lesions in patients with clinically diagnosed migraine using MRI.
  • To determine the association between lesion characteristics and migraine type (classic, common, or complicated).

Main Methods:

  • Twenty-four patients with migraine underwent MRI on a superconductive imaging unit (0.5-T or 0.6-T).
  • Lesions were identified and characterized based on signal intensity (T1 and T2-weighted images) and location.

  • Correlation between lesion presence and neurological deficits was assessed.

    • Main Results:

    • MRI revealed parenchymal lesions in 11 out of 24 (46%) migraine patients.
    • Lesions were more common in complicated migraine (4/7) than classic or common migraine (7/17).
    • Lesions included focal periventricular white matter changes and larger cortical abnormalities resembling infarcts, primarily visible on T2-weighted images.

    Conclusions:

    • Parenchymal brain changes are frequently detected in migraine patients via MRI.
    • MRI is a valuable tool for the detection and evaluation of these associated lesions.
    • Cortical lesions were associated with neurological deficits, unlike focal white matter lesions.
