Why cognitive training is important for the health status in Parkinson’s disease: preliminary evidence from a clinical three-weeks multidisciplinary intervention

Background Several non-motor symptoms are present in Parkinson's disease (PD), including increasing prevalence rates of cognitive impairment during disease progression.

Due to its multifaceted nature, PD management involves pharmacotherapy and non-pharmacotherapies, ideally in a multidisciplinary manner.

Evidence regarding the impact of multidisciplinary interventions on motor and non-motor symptoms, as well as its impact on quality of life and daily activities of living, is limited.

Methods The aim of this real-life exploratory study was to investigate the effectiveness of a three-week clinical multidisciplinary Parkinson complex therapy (Parkinson-Komplexbehandlung, PKB), which is available as standard care for PD in the German health care system.

Especially, the effect of neuropsychological attention training of 40 patients with PD was analyzed concerning their impact on motor abilities (UPDRS-III ON state), cognitive profiles and reported depressive symptoms and psychosocial function.

Results Neuropsychological data showed an improvement in response inhibition after intervention ( z  = − 2.611, p  = 0.009).

Additionally, improvements in verbal memory ( z  = − 2.318, p  = 0.020), motor functions (UPDRS-III-score; z  = − 5.163, p  < 0.001) and reduction in depression symptoms (BDI-II) ( z  = − 2.944, p  = 0.003) were also present.

Conclusions Patients with PD benefited from this multidisciplinary Parkinson complex therapy in terms of improved cognitive functioning, including attention and verbal learning, motor symptoms and emotional well-being.
