Abstract:
Objective:To investigate the characteristics of brain network reorganization in migraine patients and its relationship with the grading of right-to-left shunt (RLS) in patent foramen ovale(PFO) by integrated 3.0T structural magnetic resonance imaging (MRI),resting-state functional MRI(fMRI),and contrast-enhanced transthoracic echocardiography, thereby toexplore the mechanism underlying cognitive impairment in migraine.Methods:A total of 49 migraine patients (migraine group)and 16 demographically matched healthy subjects (healthy control group) who received diagnosis and treatment at China-Japan Union Hospital of Jilin University from September 2020 to September 2023 were selected as the study participants. Structural images (T1-weighted) and resting-state functional images were obtained from brain imaging (MRI and fMRI) data. The amplitude of low-frequency fluctuation (ALFF) algorithm was used to quantify the intensity of spontaneous neural activity in brain regions, while the Fazekas scale and the Age-Related White Matter Changes (ARWMC) scale were employed to assess white matter lesions. Participants were evaluated using the Mini-Mental State Examination (MMSE). Based on the results of contrast-enhanced transthoracic echocardiography (cTTE),the migraine group was further subdivided into A1 group (18 cases, no PFO), A2 group (17 cases, PFO with small-to-moderate RLS) and A3 group (14 case, PFO with large RLS) group, the differences in brain functional activity and cognitive function were compared among these groups.Results:By Fazekas scale scores and ARWMC scale scores, the incidence of hyperintense foci in the deep white matter regions in the migraine group were higher than those in the healthy control group: 67.3%(33/49) vs. 6/16, 61.2%(30/49) vs. 5/16, there were statistical differences ( P<0.05). Compared with the healthy control group, the migraine group exhibited higher spontaneous neural activity intensity in the brainstem,bilateral posterior cingulate cortex,left medial frontal gyrus,and left middle frontal gyrus,while showing reduced brain activity in the right angular gyrus region. The short-term delayed recall scores and total MMSE scores in the migraine group were lower than thosein the healthy control group: (1.61 ± 1.06) scores vs. (2.44 ± 0.81) scores, (25.06 ± 2.31) scores vs. (27.94 ± 1.44) scores, there were statistical differences ( P<0.05). The short-term delayed recall scores mong the A1 group, A2 group and A3 group had statistical difference( P<0.05). Conclusions:Migraine patients exhibit specific brain functional network reorganization and cognitive dysfunction, which are closely related to the degree of RLS.
