[Synergies Instead of Rivalries - Expert Opinion on the Misunderstood Roles of Continuous Intrajejunal Levodopa Therapy and Deep Brain Stimulation in the Treatment of Parkinson̓s Disease].

Abstract

In the therapy of Parkinson̓s disease, both the intrajejunal administration of Levodopa/Carbidopa Intestinal Gel (LCIG) and, more recently, Levodopa/Carbidopa/Entacapone Intestinal Gel (LECIG), as well as deep brain stimulation (DBS), are employed. These approaches differ significantly in their efficacy and side effect profiles, as well as the timing of their use. Yet, the initiation of therapy for both methods is often simultaneously considered when patients have reached an advanced stage of the disease. From the authors' perspective, however, patients may reach the milestones for the indication of one of these respective treatments at different points in the course of the disease. Individual disease progression plays a pivotal role in this regard. The concept that all patients become candidates for a specific treatment at a predefined time appears erroneous to the authors. In the context of this review, therefore, the therapeutic modalities are presented in terms of their efficacy for different symptoms, the notion of simultaneous timing of their initiation is questioned, and an individualized therapy evaluation is derived, with a focus on quality of life and participation.
