Summary

Idiopathic Parkinson's syndrome (IPS) is one of the most common neurodegenerative diseases. The prevalence and significance of this disease is continuously increasing in the course of demographic change. For many decades, the focus of diagnostics and therapy was on the motor symptoms of IPS. Only in recent years, it has been recognized that Parkinson's patients also suffer from a variety of non-motor symptoms. These have a decisive influence on the patient's quality of life. As one of the most common non-motor symptoms, 55 to 80% of IPS patients suffer from urinary dysfunction. This is associated with a very high impairment of quality of life due to a high degree of stigmatization and impairment of social participation. In clinical everyday life, Parkinson's patients regularly report the occurrence of a strong imperative urge to urinate, which occurs suddenly and is usually triggered by a certain external stimuli. Specific cognitive processing and reflection of these external stimuli seems to help overcome the imperative urge to urinate. From this clinical observation, it can be assumed that the imperative urge to urinate is subject to a certain cognitive control in the sense of targeted inhibition. The pharmacological therapy of urinary dysfunction in IPS patients is severely restricted and characterized by insufficient proof of efficacy as well as a high potential for side effects. In clinical practice, alpha-blockers and anticholinergics are frequently used, but the evidence base for IPS is inadequate. In addition, there is a highly relevant risk for Parkinson's patients of specific side effects such as orthostatic dysregulation or deterioration of cognition up to psychoses and hallucinations. This greatly limits their use especially in older IPS patients. While the use of dopaminergic medication is essential for the treatment of motor symptoms in Parkinson's patients, a large number of studies have not confirmed sufficient evidence for the efficacy of dopaminergic medication in urinary dysfunction. In addition, non-pharmacological therapy options, in particular pelvic floor training, are used to treat bladder dysfunction. Due to the lack of risk of side effects, pelvic floor training is currently recommended as a first-line therapy option for IPS patients. Initial studies have shown positive effects, but due to the lack of randomized controlled trials, a sufficient evidence base for this has not yet been established. The aim of the study is to examine whether a purely cognitive therapy approach is suitable to improve subjective and objective symptoms of urinary dysfunction in IPS patients. This therapeutic approach will be compared with the gold standard of pelvic floor training in terms of efficacy.

Interventions

Type	Name	Description
BEHAVIORAL	cognitive training	The cognitive training the investigators are planning consists of three modules which, in their entirety, are intended to help improve bladder dysfunction, which leads to psychological distress in patients: psychoeducation, training of cognitive functions and training in behavioural therapeutic techniques. The training will take place over six weeks, with two sessions per week in the first three weeks. In the following three weeks the frequency will be reduced to once a week so that there will be 9 sessions. The duration of each training session is 90 minutes.
BEHAVIORAL	pelvic floor training	At the beginning of the training, perception of the pelvic floor is the most important factor. The patients should learn the motor skills to consciously perceive and feel the pelvic floor muscles. This requires a lot of concentration and movement control. After this perception phase, the learned movements are internalized. The fine coordination of the pelvic floor muscles is more harmonious and the tensing and relaxing of the muscles becomes easier over time. In the last phase of the training, the movements and muscle activations should be internalised in such a way that they are anchored as automated movement patterns. The training will take place over six weeks, with two sessions per week in the first three weeks. In the following three weeks the frequency will be reduced to once a week so that there will be 9 sessions. The duration of each training session is 90 minutes.
