Similar changes were observed in the parahippocampal cortex, with increased levels of membrane-associated α-synuclein (280-314 ± 44-49% increase from control levels, p = 0.018) and reduced levels of membrane-associated ATP13A2 (39-55 ± 8-10% reduction from control levels, p = 0.009) in PD and DLB cases compared with controls (Figure 1B). Here, ATP13A2 is linked to Lewy body dementia.
