Putamen mean (± SEM) concentrations (pmol/mg wet weight) of catechols in post-mortem putamen from patients with Parkinson’s disease (PD, red) and controls (gray). Abbreviations: DA = dopamine; DOPAC = 3,4-dihydroxyphenylacetic acid; DOPAL = 3,4-dihydroxyphenylacetaldehyde; DOPET = 3,4-dihydroxyphenylethanol; DOPA = 3,4-dihydroxyphenylalanine. Note severely decreased DA and DOPAC, less severely decreased DOPAL and DOPET, and even less severely decreased DOPA in PD relative to controls.
