Serotonin (5-hydroxytryptamine or 5-HT) metabolites Several studies have described neuronal loss, and presence of Lewy body in serotonergic raphe nuclei in PD patients (Benito-Len et al., 1993b,c, 1997) reported a 1520% reduction of CSF 5-HT, tryptophan (precursor of 5-HT), kynurenine and 3-hydroxykynurenine (metabolites of tryptophan) levels in PD patients
Another group independently also concluded that disability progression and brain atrophy occur earlier than in the classical secondary progressive stage, with many relapsing patients exhibiting insidious progression without clinical or radiographic evidence of inflammatory disease activity, coining the term silent progression (Cree et al., 2019)
