Project objective: To improve the health care of Parkinson's disease patients in the ParkinsonNetz RheinMain+.

Hypothesis: Through the interdisciplinary and cross- sectoral networking in a tele medical network and the coordinating function of an "advanced practice nurse" (APN) specially trained for Parkinson's disease, the process quality within the network is increased and the individual health status is positively influenced.

To effectively influence the long-term course of Parkinson´s a synergistic application of an individualized therapy program, which is tailored specifically to the symptoms and disease stages, is needed. The central element of the new form of care is the implementation of a tele medical evaluation and coordination function, which controls individualized treatment processes within the network. The individualized evaluation and coordination of treatment paths is carried out within the already existing Parkinson's network RheinMain+ by a non-physician medical specialist (APN) specially trained for the indication Parkinson's disease. In-depth assessments of the individual disease situation of the patients will take place. Based on these assessments, an evidence-based and patient-centered treatment and care plan is developed. The treatment plans are monitored, controlled and evaluated by the APNs using audiovisual or tele medical communication. In addition, APNs are empowered to initiate treatment interventions necessary to implement clinical guidelines and standards, and to take charge of these interventions as part of delegation processes. The APNs ensure that patients are cared for in accordance with needs and guidelines in all areas of care. To this end, they offer, among other things, training in the handling of patients with Parkinson's disease for other professional groups involved in the treatment process and not only have the patients in mind, but also include relatives and the supporting team.

Inclusion Criteria:

• Diagnosis of primary Parkinson's syndrome (G20.-) or atypical Parkinson's syndrome (G23.-, according to the current diagnostic criteria of the Movement Disorder Society, including the criteria of at least bradykinesia and rigidity or resting tremor must be present)
• In the care regions of Hesse and Rhineland-Palatinate
• Ability to give consent present

Exclusion Criteria:

• Psychoses or other psychiatric or medical comorbidities that could affect the smooth implementation of the study protocol (e.g.

tumor disease with limited life expectancy, need for dialysis, etc.)

• Drug or alcohol addiction

• Simultaneous participation in another interventional treatment study
• Illiteracy or insufficient language skills

The participants are randomized into two groups: Interventional and control group. Neither APN nor the patients know in which group they belong until the first visit.
