Objective: The aim of this study was to compare the efficiency of group cognitive rehabilitation to patients with Parkinson´s disease (PD) in comparison to group relaxation therapy.The aim of this study was to compare the efficiency of group cognitive rehabilitation to patients with Parkinson´s disease (PD) in comparison to group relaxation therapy.

Background: Cognitive rehabilitation (CR) is one of the non-pharmacological approaches to alleviate or compensate for cognitive deficits. The goal of CR is to delay the onset of cognitive changes. Due to the relevance of cognitive deficits in PD, which can be characterized by disruption of executive functions, attention and working memory, therapeutic strategies are needed to treat cognitive decline.

Method: The prospective, single-blind, randomized clinical trial was conducted in patients with PD (n = 16). Participants underwent a neuropsychological examination to distinguish the presence of mild cognitive impairment or dementia in PD. Participants with PD were randomly allocated into cognitive rehabilitation group (CRG) and relaxation therapy group (RG). Participants in CRG (n=8) practiced cognitive functions in the context of daily living activities. CRG was focused on the restoration, compensation, and optimization strategies training. The participants of the CRG also performed exercises at home. Participants in RG (n=8) underwent music therapy and art therapy. Both types of interventions were carried out in groups, once a week for 60 minutes for 12 weeks.

Results: The statistical analysis using the Wilcoxon Signed Ranks Test showed a significant improvements in CRG demonstrated in verbal learning (p= .012), retention (p = .044), delayed recall (p = .020), memory capacity for verbal material (p = .012). In RG were significant improvement demonstrated in verbal learning (p= .012), delayed recall (p = .040), memory capacity for verbal material (p = .012) and total recall in nonverbal memory (p= .012).

Conclusion: The pilot data show the non-specific effect of the CR to the memory performance in the short-term perspective of patients with PD. Other types of interventions could be also effective in the cognitive functions of patients with PD.
