Efficacy of non-computerized cognitive rehabilitation in Parkinson's disease: A one year follow up study.

In this study, we explored the effect of non-computerized cognitive rehabilitation in patients with Parkinson's disease in comparison with an intervention with elements of music therapy after the completion of a three-month program and one year after the end of the intervention. After the initial neuropsychological examination, the respondents were divided into two intervention groups. The experimental group (n = 26) underwent a twelve-week program of cognitive rehabilitation at a frequency of 60 minutes once a week. The control group (n = 27) underwent an intervention program with elements of music therapy at the same frequency. Respondents who underwent the cognitive rehabilitation program improved in the delayed recall from visual memory in the follow-up examination after the end of the cognitive intervention. One year after the end, the effect of cognitive rehabilitation persisted in delayed recall from visual memory and in executive mental flexibility. Cognitive rehabilitation is an effective approach to compensate for cognitive deficits in P D, but other approaches to cognitive stimulation may be equally effective.

Decreased emotional creativity and its relationship with cognitive functions in Parkinson's disease: A preliminary study.

Patients with Parkinson's disease (PD) suffer from a wide range of non-motor symptoms, including cognitive deficits and impairment of emotional processing. The present study aimed to explore in PD patients compared to healthy adults the relationship between cognitive performance and emotional creativity (EC), defined as a set of cognitive abilities and personality traits related to originality and appropriateness of emotional experience. PD patients (n = 22) and healthy controls (n = 40) underwent a complex neuropsychological assessment and were administrated with the self-reported Emotional Creativity Inventory (ECI) questionnaire. To explore the relationship between cognitive tests and the ECI, a regression analysis was conducted. PD patients and healthy controls differed significantly in the EC component Preparedness as well as in the neuropsychological test battery scores. PD patients showed lower scores in cognitive tests and a lower score in Preparedness compared to healthy adults. The output of the regression analysis showed that the extent to which the neuropsychological tests relate to the ECI components is low.
