Abstract
Eighty patients with chronic insomnia and 50 normal controls were selected. Evaluation scales included Pittsburgh Sleep Quality Index, Dysfunctional Beliefs and Attitudes about Sleep, Montreal Cognitive Assessment, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Ruminative Responses Scale and Social Disability Screening Schedule. All patients and controls underwent whole-brain DTI scanning and Tract-Based Spatial Statistics (TBSS) analysis was performed. Chronic insomnia patients are mainly accompanied by white matter lesions of right posterior thalamic radiation, right sagittal tract, and right upper longitudinal tract. TBSS is helpful in the diagnosis of chronic insomnia and can reflect the changes of cognitive function.
