Researchers in the field of Parkinson’s disease have published a groundbreaking proposal in the renowned journal Lancet Neurology. Their article, published in February 2024, presents a novel, three-part classification of Parkinson’s disease based on biological principles. The German Society of Neurology (DGN) emphasises the importance of this new classification, which could revolutionise the understanding and treatment of this complex disease.
The need for a biologically based classification of Parkinson’s disease
The authors make it clear that the previous clinical categorisations no longer do justice to the current scientific findings on the complex mechanisms and biological diversity of Parkinson’s disease. In view of the increasing worldwide prevalence, with around 200,000 people affected in Germany and approximately 10 million worldwide, a precise classification and stratification is necessary for the development of targeted, disease-modifying and causal therapeutic approaches.
Basics on Parkinson’s classifications
Parkinson’s classifications are used to differentiate between different forms of Parkinson’s based on specific characteristics and criteria. These classifications are crucial for diagnosis, understanding the pathology and developing therapies. Traditionally, they are based on clinical observations, such as motor symptoms, and are complemented by imaging techniques, such as MRI. The new proposals aim to take greater account of the molecular and genetic basis of the disease.
Innovation through the “SynNeurGe” system
The proposed “SynNeurGe” (SNG) system is now a benchmark development. It allows a detailed definition of Parkinson’s disease even before the onset of symptoms by identifying the molecular basis. The SNG system consists of three main components: (1) the detection of pathological alpha-synuclein, (2) specific evidence of neurodegenerative processes through imaging techniques and (3) the detection of genetic variants that predispose to the disease. This biologically-based classification enables a more precise diagnosis and the development of targeted therapies.
The significance of the new classification for the future of Parkinson’s research
The transition to a biologically-based classification marks a turning point in Parkinson’s research. It is crucial for the future of medical research and treatment to precisely define and stratify the analysed cohorts. This is the only way to validly test the efficacy of new drugs and therapeutic approaches and develop customised treatment options.
new Parkinson’s classifications: Summary and outlook
The biologically-based, three-part classification for Parkinson’s proposed by Parkinson’s researchers represents a significant advance in the diagnosis and treatment of this disease. The introduction of the “SynNeurGe” system marks a shift from a primarily clinical to a molecularly and genetically based diagnosis. This development enables a more precise identification and classification of the disease, which forms the basis for more effective, customised therapeutic approaches and opens up new avenues in research.
