A Systematic Review and Evaluation of Non-Pharmacological Interventions for Elderly Patients with Mild Cognitive Impairment

Objective center dot This study aims to comprehensively summarize and evaluate the impact of non-pharmacological interventions on mild cognitive impairment (MCI) in elderly individuals through a systematic review of pertinent literature. The interventions include acupuncture, massage, ear point pressing, acupoint moxibustion, dietary modifications, and exercise interventions. Methods center dot A thorough literature search spanned 2017 to 2023 across databases like Zhichou, Wanfang, PubMed, CINAHL, Web of Science, and the Cochrane Library. It covered pharmacological and non-pharmacological interventions, emphasising MCI in elderly patients. Independent screening, evaluation, and data extraction were conducted and assessed via the AMSTAR 2 scale and GRADE approach. Outcome measures (e.g., MMSE, MoCA, ADL, CDT, overall efficacy) were analyzed. Results center dot Three systematic evaluations were assessed using AMSTAR 2. Two were low quality, one moderate. Limited rigor in two studies led to considering only mediumquality papers for evidence grading. Key indicators in RCTs included MMSE (eight studies), MoCA (seven studies), ADL (two studies), CDT (two studies), and overall efficacy (12 studies). GRADE evaluation revealed moderate, high, and high evidence quality for intervention efficacy at one, two, and three months respectively. MMSE evidence was low, MoCA high, ADL very low, and CDT moderate. Adverse events were reported in one publication, suggesting acupuncture's potential pain and resistance. Conclusions center dot Non-pharmacological interventions, like acupuncture, cognitive exercises, and exercise, show promise in mild cognitive impairment among the elderly. They enhance cognitive function and daily living while maintaining safety. Acupuncture notably improves MoCA scores, supported by robust evidence.
