Summary
Migraine patients show altered hypothalamic blood flow, not volume changes. Left anterior inferior hypoperfusion may indicate migraine, while right-sided changes are linked to chronic migraine.
Area of Science:
- Neurology
- Neuroimaging
- Medical Imaging
Background:
- Migraine is a common neurological disorder with suspected hypothalamic involvement.
- Previous studies have not clearly defined cerebral blood flow (CBF) and volume changes in specific hypothalamic subregions in migraine patients.
- Understanding these changes is crucial for diagnosing and treating migraine.
Purpose of the Study:
- To investigate differences in hypothalamic perfusion and volume among episodic migraine (EM), chronic migraine (CM), and normal control (NC) groups.
- To identify potential imaging markers for migraine and its subtypes.
- To explore the relationship between hypothalamic perfusion and cognitive function.
Main Methods:
- Utilized three-dimensional pseudo-continuous arterial spin labeling (3D-PCASL) on 3.0T MRI.
- Segmented the hypothalamus into 10 subregions using FreeSurfer to extract volume and CBF values.
- Employed general linear models, ROC analysis, and correlation analysis to assess intergroup differences and clinical significance.
Main Results:
- No significant differences in hypothalamic subregional volumes were observed between groups.
- Episodic migraine patients showed significantly lower CBF in the left anterior inferior hypothalamus compared to controls.
- Chronic migraine patients exhibited significantly lower CBF in the right anterior superior and right tubular superior subregions, and the whole right hypothalamus compared to controls.
- Left anterior inferior CBF demonstrated an AUC of 0.717 for discriminating migraine patients from controls.
- Right hypothalamic subregional CBF showed high specificity for distinguishing CM from controls.
- In EM patients, left anterior inferior CBF positively correlated with MMSE scores (uncorrected).
Conclusions:
- Migraine is associated with specific hypothalamic subregional perfusion abnormalities, not macroscopic volumetric changes.
- Left anterior inferior hypoperfusion may serve as a preliminary imaging marker for migraine.
- Right-sided hypothalamic perfusion alterations might be associated with chronic migraine.
- The link between hypothalamic perfusion and cognitive function requires further investigation in larger cohorts.
