Resting State Functional Connectivity Changes of the Hypothalamus in Migraine Patients: A Cross-Sectional and Longitudinal Study
Headache
S1 - Headache 1 (2:48 PM-3:00 PM)
010
Previous studies support the role of the hypothalamus in the early and interictal phase of the migraine attack.
To explore cross-sectional and longitudinal resting state functional connectivity (RS FC) changes of the hypothalamus in patients with migraine.
Using a 3.0 Tesla scanner, RS functional magnetic resonance imaging (MRI) and 3D T1-weighted scans were acquired from 92 headache-free episodic migraine patients and 73 controls. Twenty-three migraineurs and 23 controls were reexamined after a mean follow-up (FU) of 4 years. RS FC analysis was performed using a seed-region correlation approach and SPM12. 
At baseline, compared to controls, migraineurs showed a decreased RS FC between the right and left hypothalamus and the right cerebellum, left parahippocampus and bilateral orbitofrontal cortex (OFC). The left hypothalamus had also a decreased RS FC with the left middle frontal gyrus. While, the right hypothalamus had a decreased RS FC with the right inferior temporal gyrus, lingual gyrus and left calcarine cortex. At baseline, the decreased RS FC between the right hypothalamus and the ipsilateral lingual gyrus correlated with higher migraine attack frequency (r=-0.4, p<0.05, FWE corrected). After 4 years, migraine patients developed an increased FC between the hypothalamus and the OFC, bilaterally, while RS FC between the right hypothalamus and the ipsilateral lingual gyrus decreased. RS FC between the right hypothalamus and the ipsilateral OFC correlated with lower migraine attack frequency at year 4 (r=-0.6, p<0.001, uncorrected).
During the interictal phase, the hypothalamus modulates the activity of pain and visual processing areas in migraine patients. The recurrent experience of migraine attacks might disrupt the functional interaction between the hypothalamus and high-order visual processing areas. An increased RS FC between the hypothalamus and brain areas belonging to the descending pain-inhibitory pathway might reduced migraine attack frequency over time.
