There are increasingly cognitive-linguistic interventions for the elderly according to aging. However, the efficacy of cognitive-linguistic intervention for normal aging has rarely been examined by systematic literature review or meta-analysis. The purpose of this study was to evaluate the efficacy of cognitive-linguistic intervention systematically using a meta-analysis. Thirty studies published since 2000, meeting the inclusion criteria, were entered into the analysis. There were five main findings. Firstly, global cognition held a large portion of the domains in the intervention program, followed by memory, cognitive processing speed, and language, etc. Secondly, most results of treatment included domains like memory, executive function, language, and cognitive processing speed, etc. Thirdly, an average effect size of cognitive-linguistic intervention was moderate. Fourthly, memory and functional cognition in the intervention program were very effective and signigicant. Lastly, memory and problem solving had large and significant effect sizes among domains in the results of treatment. Current study provides the evidence-based information to support cognitive-linguistic rehabilitation of the elderly. This results also can contribute to prevent the cognitive-linguistic decline by aging, and to reduce the neurological diseases.
