Imagine you have a car that’s been giving you trouble. The old mechanic’s diagnostic tools just aren’t cutting it, so you’re on the lookout for something better. Well, researchers have developed new criteria for diagnosing multiple system atrophy (MSA) that outperform the old methods used for over 10 years. It’s like trading in your clunky old wrench for a shiny new diagnostic tool kit! In a study comparing the two approaches, the new movement disorder society (MDS) MSA criteria showed significantly higher sensitivity in detecting MSA compared to the 2008 criteria. This means the new criteria are better at identifying patients with MSA, especially in the early stages of the disease when accurate diagnoses are crucial. And what’s even more impressive is that the specificities of both criteria were similar, meaning they were equally good at ruling out MSA in patients who didn’t have it. This study provides strong evidence that the MDS MSA criteria are a valuable diagnostic tool for clinical practice and future therapeutic trials.

BackgroundThe 2008 criteria for the diagnosis of multiple system atrophy (MSA) has been widely used for more than 10 years, but the sensitivity is low, particularly for patients in the early stage. Recently, a new MSA diagnostic criteria was developed.ObjectiveThe objective of the study was to assess and compare the diagnostic utility of the new movement disorder society (MDS) MSA criteria with the 2008 MSA criteria.MethodsThis study included patients diagnosed with MSA between January 2016 and October 2021. All patients underwent regular face-to-face or telephonic follow-ups every year until October 2022. A total of 587 patients (309 males and 278 females) were retrospectively reviewed to compare the diagnostic accuracy of the MDS MSA criteria to that of the 2008 MSA criteria (determined by the proportion of patients categorized as established or probable MSA). Autopsy is the gold standard diagnosis of MSA, which is not available in clinical practice. Thus, we applied the 2008 MSA criteria at the last review as the reference standard.ResultsThe sensitivity of the MDS MSA criteria (93.2%, 95% CI = 90.5–95.2%) was significantly higher than that of the 2008 MSA criteria (83.5%, 95% CI = 79.8–86.6%) (P < 0.001). Additionally, the sensitivity of the MDS MSA criteria was maintained robustly across different subgroups, defined by diagnostic subtype, disease duration, and the type of symptom[s] at onset. Importantly, the specificities were not significantly different between the MDS MSA criteria and the 2008 MSA criteria (P > 0.05).ConclusionThe present study demonstrated that the MDS MSA criteria exhibited good diagnostic utility for MSA. The new MDS MSA criteria should be considered as a useful diagnostic tool for clinical practice and future therapeutic trials.
