          Abstract

          Purpose

          Persons with mild cognitive impairment (PwMCI) are at a higher risk of developing dementia than those without cognitive impairment. This research study aims to evaluate the effectiveness of a holistic health group intervention, which is based on the holistic brain health approach as well as an Eastern approach to health care, on improving the cognitive ability of Chinese PwMCI.

          Research methods

          In a randomized controlled trial (RCT), 38 Chinese PwMCI were randomly assigned to either a 10-session holistic health intervention group or the control group. The holistic health treatment group attempted to promote the acceptance of their illness, enhance memory and coping skills, develop a positive lifestyle, maintain positive emotions, and facilitate emotional support among participants. The 10-session holistic health group intervention was structured, with each session conducted once per week and ~90 minutes in length. Control group patients and their family caregivers received standardized basic educational materials that provided basic information on cognitive decline for them to read at home. The Montreal Cognitive Assessment (MoCA) test was used to assess the cognitive ability of PwMCI in the pre- and posttreatment periods by a research assistant who was blind to the group assignment of the participants.

          Results

          The paired-samples t-test indicated that the treatment group (n=18) showed significant improvement in the MoCA score, whereas the control group (n=20) did not. Moreover, 2×2 (group × time) repeated-measures analysis of covariance (ANCOVA) demonstrated that the holistic health group treatment was significantly more effective than the control intervention in improving the MoCA score, with a moderate effect size, and improving the delayed recall (ie, short-term memory), with a strong effect size, after controlling for age, sex, education, and marital status.

          Conclusion

          This present RCT provides evidence to support the feasibility and effectiveness of the holistic health group intervention in improving the cognitive and short-term memory abilities of PwMCI.

            Treatment for mild cognitive impairment: systematic review.

            More people are presenting with mild cognitive impairment (MCI), frequently a precursor to dementia, but we do not know how to reduce deterioration. To systematically review randomised controlled trials (RCTs) evaluating the effects of any intervention for MCI on cognitive, neuropsychiatric, functional, global outcomes, life quality or incident dementia. We reviewed 41 studies fitting predetermined criteria, assessed validity using a checklist, calculated standardised outcomes and prioritised primary outcome findings in placebo-controlled studies. The strongest evidence was that cholinesterase inhibitors did not reduce incident dementia. Cognition improved in single trials of: a heterogeneous psychological group intervention over 6 months; piribedil, a dopamine agonist over 3 months; and donepezil over 48 weeks. Nicotine improved attention over 6 months. There was equivocal evidence that Huannao Yicong improved cognition and social functioning. There was no replicated evidence that any intervention was effective. Cholinesterase inhibitors and rofecoxib are ineffective in preventing dementia. Further good-quality RCTs are needed and preliminary evidence suggests these should include trials of psychological group interventions and piribedil.
