Behavioral and psychological symptoms of dementia (BPSD) and care burden : Examination in the facility staff for elderly residents

Abstract

Purpose : We investigated the cognitive function, behavioral and psychological symptoms of dementia (BPSD), and activities of daily living (ADLs) of elderly individuals admitted in care facilities. Moreover, the factors affecting the care burden experienced by facility staffs were examined. Method : 24 care facilities for elderly individuals participated in the study. The Revised Hasegawa Dementia Scale (HDS-R), Japanese version of the Neuropsychiatric Inventory (NPI), and Crichton Geriatric Behavioral Rating Scale (CGBRS) were used to evaluate cognitive function, BPSD, and ADL, respectively. The short Japanese version of the Zarit Burden Interview was used to assess the care burden. A multiple regression analysis was conducted with data obtained from 464 elderly individuals who fulfilled all the scales. Results : The care burden was correlated to the scores of HDS-R, but not with those of dysphoria/depression and disinhibition of NPI, restlessness of CGBRS, and subjective mood of CGBRS (R2 = 0.309, p < 0.005). Conclusion : Dysphoria/depression, disinhibition, restlessness, and subjective mood, but not cognitive decline, have an effect on the care burden experienced by facility staffs who manage elderly individuals. These results indicated that the appropriate diagnosis and treatment of BPSD are important in reducing the burden of facility staffs. J. Med. Invest. 67 : 236-239, August, 2020
