Evaluation of Computer-Based Cognitive Training on Mild Cognitive Impairment in Parkinson's Disease (PD-MCI): Α Review.

Background/

Objectives

Mild cognitive impairment in Parkinson's disease (PD-MCI) affects approximately 20-50% of patients, and it is associated with an increased risk of dementia. Computer-assisted cognitive interventions (CCTs) have been proposed as a promising method of improving cognitive function in these patients. This review aims to (1) demonstrate the effectiveness of computer-based intervention in PD-MCI, and (2) determine the most effective iteration.

Methods

A review was performed using PubMed, Google Scholar, and ScienceDirect. Full texts of randomized clinical trials (RCTs) involving CCT intervention in PD-MCI and published in English language journals between 2014 and 2024 were included.

Results

Of the 747 studies identified, 6 studies fulfilled the eligibility criterion for this review. Patients receiving CCTs showed significant improvements in global cognition and executive function, while mood was not significantly affected in most studies.

Conclusions

CCT improves cognitive functions, particularly memory and executive abilities, but has little effect on mood. Although the results are encouraging, there are potential methodological biases that need to be considered.
