Altered neurovascular coupling in mild cognitive impairment and Alzheimer's disease: Associations with polysomnography-derived sleep parameters and cognition
Background Neurovascular coupling (NVC) reflects the coordination between neuronal activity and cerebral perfusion, and impaired NVC has been implicated in cognitive decline. Objective To characterize imaging-based NVC-related measures at global and regional levels and examine their associations with polysomnography-de...
