Differential effects of cognition-focused interventions for people with Alzheimer's disease: A meta-analysis.

Objective: The efficacy of cognition-focused interventions (CFIs) for the treatment of Alzheimer's disease (AD) has been questioned recently. To date, the specific effects of cognitive rehabilitation (CR), cognitive training (CT), and cognitive stimulation [CS] have not been analyzed due to inconsistencies in the use of the comparison groups. This work aims to analyze the differential effects of CFIs by removing the influence of the comparison group from the estimates of the effects.
