ABSTRACT
Evolving evidence has supported the existence of two anatomically distinct Lewy-related pathology (LRP) types. Investigation spinal cord and peripheral LRP can elucidate mechanisms Lewy body disorders origins synuclein accumulation. Still, very few unselected studies have focused on in these regions. Here we analysed cord, dorsal root ganglion, adrenal gland population-based Vantaa 85 + study, including every ≥ years old citizen living city 1991 (n = 601). Samples from (C6-7, TH3-4, L3-4, S1-2) were available 303, lumbar ganglion 219, 164 subjects. Semiquantitative scores determined immunohistochemically stained sections (anti-alpha-synuclein antibody 5G4). ventral horns thoracic intermediolateral column, compared with brain LRP, previously according to DLB Consortium criteria by caudo-rostral versus amygdala-based classification.
