[Abstract] Objective: To investigate the abnomality of spontaneous neural activity in patients with leukoaraiosis using blood oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI).Materials and Methods: Nineteen patients with mild LA(The mild LA group), twenty-one patients with severe LA (The severe LA group) and nineteen age-matched healthy controls(The HC group) underwent the rs-fMRI scans, and the ALFF maps were computed and analysed.Results: Compared with the mild LA group, the severe LA group demonstrated decreased ALFF in the left precuneus and right angular gyrus(P<0.05, corrected). Moreover, compared with healthy controls, the severe LA group showed significantly decreased ALFF in the left precuneus, right angular gyrus and right middle frontal gyrus (P<0.05, corrected).Conclusion: Patients with LA show abnormality of spontaneous neural activity.
