Summary: Researchers have discovered a diagnostic in spinal fluid that you accurately identify Parkinson’s disease in its earlier stages. They measured the misfolding of the alpha-synuclein ( Syn ) protein, a key component of the disease, using a patented immuno-infrared sensor (iRS ) technology.
Clinical symptoms typically only look after significant and irreversible brain injury, so earlier diagnosis is crucial. The program could also facilitate the creation and validation of novel Parkinson’s therapies beyond diagnosis.
Important Information
- Early Detection: Parkinson’s is predicted by misfolded alpha-synuclein ( Syn ) in spinal fluid with over 90 % sensitivity and specificity.
- Advanced Technology: The tax system validates a technique used in Alzheimer’s tests that identifies protein misfolding.
- Medical Potential: By tracking the disease progression, the diagnostic may aid in the development and testing of new Parkinson’s treatments.

A neurological disorder called Parkinson’s is typically identified in the late stages based on scientific signs, most notably motor disorders.
However, the mind is now greatly and permanently damaged at this point. Additionally, because the disease has numerous manifestations and overlaps with other conditions, diagnosis is challenging and frequently wrong.
A marker in the lumbar substance, which facilitates a reliable treatment at an early stage and can provide insight into the progression of the disease and the effects of a treatment, has been discovered by researchers from the Ruhr University Bochum, Germany’s PRODI Center for Protein Diagnostics and the biotechnology company betaSENSE.
On April 25, 2025, they publish their findings in the journal EMBO Molecular Medicine.
An irresistible condition known as Parkinson’s disease
The loss of serotonin nerve cells in the brain, which typically leads to more motor deficits as the symptoms development, is a hallmark of Parkinson’s disease. Dopamine products can make up for the loss and partially lessen the symptoms.
The key protein alpha-synuclein ( Syn )’s misfolding from helical to sheet-rich structures is crucial for the development of Parkinson’s disease.
” These misfoldings cause the proteins to become thick, causing the formation of larger structures, or oligomers,” the statement reads. According to Professor Klaus Gerwert, founding and managing director of PRODI and CEO of betaSENSE, the oligomers therefore form much fibrillar filaments that the brains can assemble into macroscopically big Uv bodies.
innovative platform technology
The Bochum-based researchers found that this misfolding of’Syn in body-fluids is a useful diagnostic for the treatment of Parkinson’s disease in two separate therapeutic groups with a full of 134 individuals.
The Parkinson’s centers in Bochum ( St. Josef Hospital, Professor Lars Tönges, Professor Ralf Gold ) and Kassel ( Paracelsus-Elena-Klinik, Dr. Sandrina Weber, Professor Brit Mollenhauer ) used as the subjects for the study.
The betaSENSE GmbH’s patented iRS ( immuno-infrared sensor ) technology was used to conduct the measurements.
The taxpayer technology has already been safely used by betaSENSE to identify Alzheimer’s disease. In this instance, it was demonstrated that the misfolding of the marker A may, with great accuracy upward to 17 years before the clinical diagnosis, indicate the risk of Alzheimer’s memory at a later period.
Klaus Gerwert explains,” We have now transferred this technique to Parkinson’s for the misfolding of Syn.”
Development of Parkinson’s medications
The technology may also aid in developing innovative effective substances and demonstrate their efficacy in clinical trials, in addition to medical applications.

Abstract
Using the iRS System, the iRS System to measure the alpha-synuclein misfolding as a fluid diagnostic for Parkinson’s disease
The pathophysiology of Parkinson’s disease ( PD ) is impacted by the misfolding and aggregation of alpha-synuclein ( Syn ). An earlier and differential diagnosis of PD also presents a significant problem despite significant advancements in testing.
The immuno-infrared sensor (iRS ) platform was developed to measure Syne misfolding. We analyzed cerebrospinal fluid ( CSF ) from two cohorts of disease controls, PD cases, and atypical Parkinsonian disorders.
We were able to separate PD/MSA from controls by determining the PD/MSA’s SYN misfolding by iRS with an AUC of 0.90 ( n = 134, 95 % CI: 0.85–0,96 ). Using two levels, dividing people by their level of misfolding with an intermediate place, was used to divide them between unaffected and affected.
Controls versus PD/MSA cases were classified with 97 % sensitivity and 92 % specificity when comparing the affected/unaffected cases.
The spectroscopic analysis revealed misfolding from a sheet-enriched SYN in PD and MSA cases to an SYN in handles. Additionally, a second subgroup analysis suggested that individual stratification could occur in cases with clinical overlap.
The iRS, which directly measures all SYN conformers, is an improvement over the SYN seed-amplification assays ( SAAs ), which only amplify competent conformers for seeding.
