ABSTRACT
OBJECTIVE:
We aim to provide an up-to-date systematic review and meta-analysis of the effects of cognitive stimulation (CS) on cognition, depressive symptoms, and quality of life in persons with dementia. Factors affecting the treatment effect were examined.METHODS:
A literature search was performed on databases of MEDLINE, EMBASE, PsycINFO, CINAHL Plus, and Cochrane Library up to 7 March 2019. Only randomised controlled trials investigating the effects of CS in persons with dementia were included. The outcome measures were cognitive function, depressive symptoms, and quality of life.RESULTS:
20 randomised controlled trials with a total of 1251 participants (intervention group 674; control group 577) were included for meta-analysis. Most participants had mild to moderate dementia. CS had a significant positive small-to-moderate effect on cognition (Hedges's g = 0.313, p < 0.001). Heterogeneity of CS was low to moderate (Q=30.5854, df=19, p < 0.05, I2 = 37.877%). Inconclusive results were found for depressive symptoms and quality of life.CONCLUSION:
CS has a significant positive effect on cognitive function, but its effect on depressive symptoms and quality of life was inconclusive. Future studies with more robust methodology establishing evidence of its efficacy are required.Palabras clave
