title: The cortical thickness correlates of clinical manifestations in the mid-stage sporadic Parkinson's disease.
abstract: The cortical thickness has gained an extensive attention as a pathological alteration of sporadic Parkinson's disease (sPD), the alteration of pathological cortical thickness may distinctly contribute to the consistent clinical manifestations. Therefore, we investigated the cortical thickness correlates of clinical manifestations in the mid-stage sPD from the Han population of Chinese mainland (HPCM). A sample of 67 mid-stage sPD patients and 35 matched controls from HPCM were performed a corticometry of magnetic resonance imaging (MRI) and the assessment of clinical manifestations including the demographic and disease-related characteristics, and underwent the final analysis of the cortical thickness correlates with the clinical manifestations. In our result, we demonstrated that no significant differences in the demographic characteristics were found among the two groups. The tests of clinical disease-related characteristics demonstrated that the significant differences in the Hoehn and Yahr scale, the UPDRS Part I-IV, the symptom-dominant side (right/left/double), the tremor subscoree off (e), the tremor subscoref on (f), Webster, MMSE, HDS-R, DF, DB, SVFT, SDS, HAMD17, HAMD 24, CDT, CDR, LEDD and PDSI were observed between the mid-stage sPD patients and the controls. The analysis about the cortical thickness correlates with the clinical manifestations revealed that a significant correlation between UPDRS-I and Frontal-Sup-Orb-R and Rectus-R; DB and Frontal-Sup-Orb-R and Frontal-Inf-Orb-R; SDS and Frontal-Sup-Orb-R, Frontal-Mid-Orb-R, Rectus-R and Cingulum-Ant-R respectively in the mid-stage sPD patients from HPCM. Our data showed that the cortical thinning in the right frontal Orb, rectus and cingulum were the pathological base of some clinical manifestations including the cognitive impairment, hallucinations, psychosis, the depressed mood, the anxious mood, apathy, the sleep problems, the nighttime or/and daytime sleepiness, the short term memory stores and the central execution, as well as the sexual desire disorder in the mid-stage sPD patients, suggesting that the dysfunctions of brain regions of some cortical thinning are closely correlated with some clinical manifestations of the mid-stage sPD.
