ABSTRACT
Objectives:
To analyze the potential biomarkers of behavioral and psychological symptoms of dementia (BPSD) in patients with Alzheimer′s disease (AD) continuum.Methods:
A prospective cohort study was consecutively conducted on 179 patients with AD continuum (135 presented with BPSD, 44 patients without BPSD as control) from Capital Medical University, Beijing Tiantan Hospital, the Chinese imaging biomarkers and lifestyle cohort between January 1, 2021 and December 31, 2022. Gender, age, body max index, education level, diagnosis, the apolipoprotein E epsilon4 allele (APOE ε4) carrier status, the scores of the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), cerebrospinal fluid (CSF) AD-related pathological biomarkers (Aβ 42, Aβ 40, Aβ 42/40, tTau, pTau181), and blood biomarkers (white blood cell count, red blood cell count, hemoglobin, platelet, total bilirubin, albumin, total cholesterol, triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting glucose, erythrocyte sedimentation rate, homocysteine, vitamin B 12, folate) were compared between the two groups by using hypothesis testing and univariate logistic regression analysis. Multivariate logistic regression analysis was used to analyze the potential biomarkers associated with BPSD in patients with AD.Results:
Among the 179 patients with AD continuum in the final analysis, 77 patients were men, 102 cases were women; 35 patients were identified with mild cognitive impairment (MCI) due to AD and 144 patients with AD dementia stage, the mean age was (66.54±9.75) years. Compared with those in control group, patients with BPSD had lower cerebrospinal fluid (CSF) Aβ 40 and blood hemoglobin levels [7.08 (4.42, 15.42) vs 9.62 (6.45, 12.12) pg/L, (132.70±13.37) vs (138.80±14.38) g/L] ( U=-1.856, t=2.579, P<0.05). The levels of CSF Aβ 40 ( OR=0.030, 95% CI 0.001-0.760) and blood hemoglobin ( OR=0.051, 95% CI 0.004-0.670) were independently negatively associated with BPSD in patients with AD continuum (both P<0.05).Conclusion:
The decreased levels of CSF Aβ 40 and blood hemoglobin could be considered as potential biomarkers in detecting BPSD in patients with AD continuum.
