To investigate the incidence of postoperative neuropsychic dysfunction (PND) in Parkinson's disease (PD) patients undergoing deep brain stimulation (DBS) and to analyze its influencing factors. A prospective study was conducted between January 2020 and December 2022, recruiting PD patients from the Functional Neurosurgery Outpatient Clinic of Beijing Tiantan Hospital, Capital Medical University. All patients were scheduled to undergo bilateral subthalamic nucleus (STN)-DBS surgery. Perioperative clinical data were collected, and PND (outcome measure) within 3 days postoperatively was assessed using the Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Hamilton depression and anxiety scales, and 3-minute diagnostic interview for confusion assessment method (3D-CAM). Multivariate Logistic regression was used to analyze the influencing factors of PND. A total of 216 PD patients were enrolled. Within 3 days after DBS surgery, 77 patients (35.6%) developed PND, including 24 cases (31.2%) of depression or worsening depression, 16 cases (20.8%) of anxiety or worsening anxiety, 13 cases (16.9%) of cognitive decline, and 24 cases (31.2%) of delirium. Univariate analysis revealed that dural opening method, dural opening time, intraoperative improvement rate of the unified Parkinson's disease rating scale -Ⅲ (UPDRS-Ⅲ) score, and postoperative intracranial air volume were significantly different between PND and non-PND patients (all PD patients have a high incidence of PND after DBS surgery. Sex, postoperative intracranial air volume, and the degree of improvement in PD motor symptoms can influence the risk of PND. These findings highlight the importance of individualized management based on sex, improving surgical techniques, and enhancing monitoring of neuropsychiatric status to optimize the efficacy of DBS surgery.

Objective Feasibility application of microelectrode recording(MER)during sub thalamic nucleus deep brain stimulation(STN-DBS)implantation under desflurane general anesthesia(GA)in patients with Par-kinson's disease(PD).Methods A prospective cohort of 20 PD patients undergoing STN-DBS under desflurane general anesthesia were enrolled.Intraoperative MER quality,pos-operative acute pain,cognitive function,anxi-ety/depression status,quality of life,and clinical efficacy of DBS were evaluated.Results Among the patients,14 were male with average PD duration of(8.1±3.6)years.Hoehn-Yahr staging averaged 2.8±0.5 in"on"state and 2.3±0.5 in"off"state.The mean DBS surgery duration was 87.4 minutes.Highly normalized root-mean-square(NRMS)signals were successfully recorded in all cases,with remedial measures applied in 4 pa-tients to achieve satisfactory MER signals.Post-operative Visual Analogue Scale(VAS)pain scores on days 1,2,and 3 were 3.7±2.2,2.8±1.6,and 1.8±2.0,respectively.Montreal Cognitive Assessment(MoCA)scores showed no statistical difference during hospitalization as compared to pre-operative values,but significantly de-creased at 6-month follow-up(24.3±4.1 vs.21.5±3.5,P<0.05).All patients demonstrated significant reduc-tion in Hamilton Anxiety Scale(HAMA),Hamilton Depression Rating Scale(HAMD),and Parkinson's disease Questionnaire-39(PDQ-39)scores at 6-month follow-up.The unified Parkinson's disease rating scale(UPDRS-Ⅲ)improvement rates were 51.4%±39.2%(medication-on)and 61.6%±26.8%(medication-off)respectively with Levodopa Equivalent Daily Dose(LEDD)improvement rate of 48.6%±23.0%.Conclusions Desflurane general anesthesia is safe and feasible for electrods implantation in STN-DBS of PD patients,without interfering with intra-operative MER or postoperative outcomes.
