Impact factors of behavioral and psychological symptoms of dementia in patients with Alzheimer′s disease / 中华健康管理学杂志

ABSTRACT

Objective:To explore the impact factors of behavioral and psychological symptoms of dementia (BPSD) in patients with Alzheimer′s disease (AD).Methods:The clinical data of 116 patients with AD admitted to the Outpatient Department of Cognitive Neurology of Beijing Tiantan Hospital, Capital Medical University from June 1, 2021 to March 1, 2022 were collected continuously. The patients were divided into BPSD group ( n=85) and control group ( n=31) according to the presence or absence of BPSD. The sociodemographic data (gender, age, body mass index, years of education), the medical history of hypertension, diabetes mellitus, hyperlipidemia, and the scores of the Mini-Mental State Examination (MMSE), the Activity of Daily Living (ADL), Mini-Nutritional Assessment scale (MNA) and Caregiver Burden Inventory (CBI) were compared between the two groups with hypothesis test and univariate logistic regression analysis. The statistically significant factors in hypothesis test and univariate logistic regression analysis were enrolled in multivariate logistic regression analysis to further identify the factors associated with BPSD in patients with AD. Results:There was no significant statistics differences in the gender, age, body max index, years of education and the medical history of hypertension, diabetes mellitus, hyperlipidemia between the two groups (all P>0.05). Compared with control group, patients with BPSD had lower scores of MMSE and MNA scales [(16.24±7.52) vs (20.81±5.09) points, (21.62±3.75) vs (24.87±2.89) points] (both P<0.001) and higher scores of ADL and CBI scales [29.00 (22.00, 38.50) vs 22.00 (20.00, 25.00) points, 25.00 (12.50, 41.00) vs 3.00 (0.00, 11.00) points](both P<0.001). The multiple logistic regression analysis demonstrated that the decreased MNA scores ( OR=0.762, 95% CI 0.631-0.922; P=0.005) and elevated CBI scores ( OR=1.077, 95% CI 1.029-1.128; P=0.002) were associated with BPSD in patients with AD. Conclusion:The malnutrition or the risk of malnutrition and greater caregiver burden can independently contribute to the onset of BPSD in patients with AD.
