    • Corticobasal syndrome (CBS) is associated with 4-repeat tauopathy and/or Alzheimers disease pathologies. To examine tau and amyloid-beta (A beta) deposits in CBS patients using positron emission tomography (PET). Eight CBS patients and three healthy individuals lacking amyloid pathology underwent PET with [C-11]PBB3 for tau imaging, and [C-11]AZD2184 for A beta. Subcortical and cortical binding of [C-11]PBB3 was compared between A beta(-) and A beta(+) CBS patients and reference group. Postmortem analysis was done in one CBS patient. Three CBS patients were considered A beta(+). Total binding was higher in all patients compared to the reference group. Similar regional binding profiles of [C-11]PBB3 in A beta(+) and A beta(-) CBS patients were found. Elevated [C-11]PBB3 binding in pallidum was observed in all CBS patients. Cortical [C-11]PBB3 binding was higher in A beta(+) compared to A beta(-) patients. Postmortem analysis of a CBS patient revealed corticobasal degeneration neuropathology and [C-11]PBB3 autofluorescence in some tau-positive structures. [C-11]PBB3 is elevated in CBS patients with binding in relevant areas capturing some, but not all, 4-repeat tauopathy in CBS.
