The Potential Effects of Oxidative Stress-Related Plasma Abnormal Protein Aggregate Levels on Brain Volume and Its Neuropsychiatric Consequences in Parkinson’s Disease

Figure 1

The plasma abnormal protein aggregate levels (pg/mL) of the participants showed that the two PD patient groups had significantly increased plasma levels of NfL, T-Tau, and α-synuclein but reduced levels of AB40 compared to normal controls. Furthermore, a significantly higher NfL level was noted in the PDCD group, as compared to both the normal control and the PDN group. , .
