Abstract

Objective: Sleep affects systemic inflammation and amyloid deposition, and sleep disturbance is known to be a risk factor for cognitive decline. To date, literatures on the relationship between peripheral inflammatory markers and sleep in Alzheimer’s dementia and mild cognitive impairment patients have been scarce. The aim of this study was to determine the correlation between sleep and C-reactive protein (CRP) in Alzheimer’s dementia and amnestic mild cognitive impairment patients.
Methods: A total of 81 patients were divided in to four groups: amyloid negative healthy control, amyloid negative amnestic mild cognitive impairment, amyloid positive amnestic mild cognitive impairment, and amyloid positive Alzheimer’s dementia.
Demographic data and cognitive measurement through the Consortium to Establish a Registry for Alzheimer’s Disease were conducted. Amyloid positivity status was attained through positron emission tomography scans using [18F]-flutemetamol. The quality of sleep was evaluated by the sleep item of Korean Neuropsychiatric Inventory (K-NPI-SLEEP), and peripheral blood tests were conducted to measure CRP.
Results: There was no statistically difference in CRP levels or K-NPI-SLEEP scores among four groups. Moreover, there was no association between K-NPI-SLEEP and CRP in four groups.
Conclusion: Since K-NPI-SLEEP score shows overall, subjective sleep problems, further follow-up studies in consideration for objective sleep studies to unravel the relationship of peripheral inflammatory markers and sleep in amnestic mild cognitive impairment and Alzheimer’s dementia patients.
