The relationship between nutritional status and cognitive function in Alzheimer's disease / 肠外与肠内营养

ABSTRACT

Objective:To investigate the relationship between nutritional status and cognitive function in patients with Alzheimer's disease (AD),and to provide rationale for clinicians in nutrition intervention of AD patients.Methods:Sixty cases of elderly AD patients and 50 cases with normal elderly control were enrolled from the neurological department.Nutritional status and cognitive function were assessed using the laboratory parameters,mini nutritional assessment method (short-form Mini-Nutritional fine assessment,MNA-SF) and MMSE (Mini-Mental State,Examination,MMSE) survey.Results:Compared with control group,the AD group had significantly different laboratory index and MNA-SF score (P ＜ 0.05).MNA-SF scores were positively correlated with MMSE scores in patients with AD (r =0.59,P ＜ 0.05).Conclusion:The incidence of malnutrition in AD patients is high,and it is related to their cognitive function.The nutritional knowledge should be strengthened among doctors and nurses treating patients with AD.
