Fig. 4From: Interaction of systemic oxidative stress and mesial temporal network degeneration in Parkinson’s disease with and without cognitive impairmenta The correlation between disease severity and functional connectivity within the MTL functional network. The reduced fc-CC values of the MTL functional network were associated with worsening clinical symptoms, including UPDRS part I (mentation and mood) and part III (motor) and total scores (controlling for age and sex, Bonferroni corrected P < 0.05). b The correlation between cognition and functional connectivity within the MTL functional network. The reduced fc-CC values of the middle occipital lobe were associated with worsening cognitive impairment, including UPDRS part I (mentation and mood), MMSE, attention, and memory function scores (controlling for age and sex, Bonferroni corrected P < 0.05)Back to article page
