Meta-analysis about cognitive intervention effect applied to dementia patients

Area of Science:

• Gerontology
• Neuroscience
• Cognitive Psychology

Background:

• Dementia significantly impacts cognitive function and quality of life.
• Cognitive interventions are explored as a therapeutic strategy for dementia.
• Meta-analysis provides a robust method for synthesizing evidence on intervention effectiveness.

Purpose of the Study:

• To evaluate the effectiveness of different cognitive interventions for dementia patients.
• To compare the impact of memory training, computer-based interventions, and multiple cognitive interventions.
• To provide an evidence-based foundation for selecting cognitive interventions in dementia care.

Main Methods:

• Systematic literature search and selection of 13 studies (2001-2015).
• Qualitative assessment using Jadad scale and quantitative meta-analysis of cognitive function data.
• Calculation of effect sizes for different intervention types.

Main Results:

• Memory training interventions demonstrated a large effect size.
• Computer-based interventions showed a medium effect size.
• Multiple cognitive interventions had a small effect size, with all results statistically significant (p < 0.05).

Conclusions:

• The order of effectiveness for dementia patients was memory training, followed by computer-based intervention, then multiple cognitive intervention.
• Findings support memory training as a highly effective cognitive intervention for dementia.
• This meta-analysis offers an objective basis for clinical decision-making in dementia cognitive intervention.
