The pathogenesis of Alzheimer’s disease (AD) is still unclear. As a neurodegenerative disease, AD is a brain disorder characterised by a general loss of neurological abilities. The course of the disease is usually divided into early (memory impairment, visual-spatial disorientation, etc.), middle (loss of independent living ability), and late (severe mental decline, limb rigidity etc) and finally, most patients die from accompanying infections. The aim of this study was to explore the effect of resveratrol combined with donepezil hydrochloride on inflammatory factor level and cognitive function level of patients with AD. This study is a double-blind randomised controlled study which enrolled a total of 90 AD patients. Participants were randomly assigned to the control group (CG) or the experimental group (EG). Results show that: - there weren’t obvious difference in the total incidence rate of adverse reactions between the two groups, proving that the combination was safe and reliable in treating AD. - after treatment, various clinical indicators were lower in EG than in CG. - the number of cases with adverse reactions was lower in EG than in CG. - the Functional Independence Measure score was higher in EG than in CG after treatment which demonstrates that the drug combination could enhance the treatment effect. - compared with CG after treatment, EG obtained higher Mini-Mental State Examination score and significantly lower Alzheimer’s Disease Assessment Scale-Cognitive Subscale score. Authors conclude that further well-designed prospective studies are required to obtain higher-grade evidence as a reference basis for AD treatment
