Round 1

Reviewer 1 Report

This manuscript presents a review on the effectiveness of virtual reality cognitive training (VRCT) and conventional computer-based cognitive training (CBCT) in the treatment of mild cognitive impairment (MCI).

The strategies designed to explore the literature related and to select the studies of interest can be considered acceptable and sufficient to draw an updated 'big picture' of the target research field. Analytical tools are also appropriate. Meta-analyzes based on forest plots have been very illustrative.

On the formal level, simple and direct writing style, fluent reading, well-segmented discussion, convincing conclusions, in short, a very good review of the topic of interest.

I have not identified any relevant areas for improvement.

Reviewer 2 Report

Thank you for the opportunity to review this interesting paper. The authors present a systematic review to evaluate the effectiveness of two different kinds of intervention regimes, namely virtual reality cognitive training (VRCT) and computer-based cognitive training (CBCT) for individuals with mild cognitive impairment (MCI). 320 studies were yielded by 5 different databases. Even if the authors recognize the VRCT is the most effective intervention in many cognitive domains, they underline that further research is needed to reach consensus on which are the conditions that can address the better choice, because of the heterogeneity of the considered studies.
The paper is enriched by a very interesting meta-analysis: the authors could consider to highlight this approach in the paper title.
