Changes in the overall neurochemical composition of cerebrospinal fluid (CSF) under therapy may yield additive diagnostic and predictive information. With this prospective proof\u2010of\u2010concept and feasibility study, we evaluated non\u2010targeted CSF proteomic profiles by mass spectrometry along with basic CSF parameters of 10 adult patients with SMA types 2 or 3 before and after 10\u00a0months of nusinersen therapy, in comparison with 10 age\u2010 and gender\u2010matched controls. These data were analyzed by bioinformatics and correlated with clinical outcomes assessed by the Hammersmith Functional Rating Scale Expanded (HFMSE). CSF proteomic profiles of SMA patients differed from controls. Two groups of SMA patients were identified based on unsupervised clustering. These groups differed in age and expression of proteins related to neurodegeneration and neuroregeneration. Intraindividual CSF differences in response to nusinersen treatment varied between patients who clinically improved and those who did not. Data are available via ProteomeXchange with identifier PXD016757. Comparative CSF proteomic analysis in adult SMA patients before and after treatment with nusinersen\u2010identified subgroups and treatment\u2010related changes and may therefore be suitable for diagnostic and predictive analyses.<\/jats:p><\/jats:sec><jats:sec><jats:label\/><jats:p>\n<jats:boxed-text content-type=\"graphic\" position=\"anchor\"><jats:graphic
