People with Parkinson’s disease (PD) exhibit multi-system damaged. Medication mainly targets impairments related to dopaminergic lesions. Moreover, in later stages of the disease, medication becomes less effective. Rehabilitation therapy is believed that it can improve multiple functional disorders, including myotonia, bradykinesia, and postural gait abnormalities. It not only reduces the severity of non-motor symptoms and improves the quality of life in PD patients, but also delays the development of PD and improves the activity of daily life of patients. This article summarizes the progress of rehabilitation assessment and the therapy of PD.
Objective To assess the changes in depression symptoms in patients with Parkinson’s disease (PD) receiving combined treatment of deep brain stimulation (DBS) and antiparkinsonian drug therapy (DT) compared with under DT alone. Methods Related literature was retrieved from electronic databases, including PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Data, and VIP databases. Stata 14.0 software was used for statistical analysis. Network meta-analysis was performed using frequentist model to compare different interventions with each other. Results Five cohort studies and seven randomized controlled trials (RCTs) were included. The total number of participants was 1241. Assessed by the Beck Depression Inventory (BDI) score as the primary outcome, patients who received DT alone showed worse outcome in depression as compared to those who received subthalamic nucleus (STN)-DBS plus DT [standardized mean difference (SMD)=0.30, 95% confidence interval (CI) (0.01, 0.59), P<0.05], and there was no significant difference between the patients receiving globus pallidus interna (GPi)-DBS plus DT and those receiving STN-DBS plus DT [SMD=–0.12, 95%CI (–0.41, 0.16), P>0.05] or those receiving DT alone [SMD=–0.42, 95%CI (–0.84, 0.00), P>0.05]. Assessed by BDI-Ⅱ as the primary outcome, patients who received DT alone showed worse outcome in depression than those who received STN-DBS plus DT [SMD=0.29, 95%CI (0.05, 0.54), P<0.05]; compared with STN-DBS plus DT and DT alone, GPi-DBS plus DT was associated with better improvement in depression [SMD=–0.26, 95%CI (–0.46, –0.06), P<0.05; SMD=–0.55, 95%CI (–0.88, –0.23), P<0.05]. The ranking results of surface under the cumulative ranking curves showed that DBS plus DT had a better superiority in depression symptoms, and GPi-DBS was better than STN-DBS. Conclusion Compared with DT, STN-DBS plus DT is more likely to improve the depressive symptoms of PD patients, and GPi-DBS may be better than STN-DBS.
Objective To understand the frailty status and main influencing factors of elderly Parkinson’s disease (PD) patients. Methods The elderly PD patients who attended the Department of Neurology of Changshu Hospital of Traditional Chinese Medicine between November 2023 and March 2024 were selected. The patients’ frailty conditions were investigated using general information questionnaire, Chinese version of Tilburg Frailty Indicator, Hoehn-Yahr Rating Scale, Mini-Nutritional Assessment Short Form, Movement Disorder Society-Unified PD Rating Scale Part Ⅲ, PD Sleep Scale-2, and Mini-Mental State Examination. Multiple linear regression analysis was used to further determine the influencing factors of the frailty status in elderly PD patients. Results A total of 170 PD patients were included. Among them, 117 cases (68.82%) had frailty, while 53 cases (31.18%) had not frailty. The average score for frailty was (6.48±3.34) points, the average score for nutritional status was (11.89±1.65) points, the average score for motor function was (27.40±13.73) points, the average score for sleep quality was (16.05±7.76) points, and the average score for cognitive status is (26.25±4.51) points. The Pearson correlation analysis results showed that PD patient frailty was positively correlated with motor function and sleep quality (P<0.01), and negatively correlated with nutritional status and cognitive status (P<0.01). The results of multiple linear regression analysis showed that age, education, place of residence, course of disease, Hoehn-Yahr Rating, nutritional status, motor function, cognitive status and sleep quality were the influencing factors of frailty in PD patients (P<0.05). Conclusions Elderly PD patients are prone to frailty. Healthcare professionals should pay attention to early screening for frailty in this population and provide timely and effective interventions to prevent or delay the onset of frailty in patients.
Objective To observe the changes of retinal nerve fiber layer (RNFL) thickness and its correlation with visual field mean defects（MD）in Parkinsonprime;s disease (PD).Methods Fifteen eyes of 15 PD patients in early stage and 18 eyes of 18 normal controls undertook RNFL examination by Stratus OCT3. Circular scans (diameter is 3.46 mm) were taken around the optic nerve head including eight quadrants (superior, inferior, temporal, nasal, temporalsuperior, temporalinferior, nasalsuperior and nasalinferior). The RNFL thickness in different quadrants in the two groups was analyzed. The visual field of PD patients was measured by central 302 program of Humphery750 visual field analyzer, and the MD was recorded. The correlation between RNFL thickness and MD was analyzed by linear correlation and regression analysis.Results RNFL thicknesses of superior, inferior, temporal, nasal, temporalsuperior, temporalinferior, nasalsuperior, nasalinferior and average RNFL thickness in the control group were (132.7plusmn;17.4), (141.5plusmn;15.3) ,（83.2plusmn;17.5）, (83.7plusmn;22.3) ,（120.8plusmn;21.2）, (117.9plusmn;24.5) ,（109.6plusmn;20.6）,（110.2plusmn;27.7）, and（109.9plusmn;8.5）mu;m respectively, while in the PD group they were (128.1plusmn;25.3) , (128.6plusmn;13.2) , (68.7plusmn;13.5) , (76.5plusmn;17.8) ,（102.6plusmn;23.7）, (103.3plusmn;14.1) ,（101.2plusmn;20.9）,（96.6plusmn;15.0）,（102.3plusmn;11.9） mu;m. Compared with each other, the differences of RNFL thickness of inferior, temporal, temporalsuperior, temporalinferior and average RNFL thickness were statistically significant（t=2.595，2.700，2.330，2.153，2.131；P=0.014，0.011，0.026，0.040，0.041）. There was a close negative relationship between average RNFL thickness and MD in PD patients (r=-0.933，P＜0.0001). Conclusions RNFL thickness was significantly thinner in PD patients than that in the normal controls. There was a negative relationship between RNFL thickness and MD in PD patients.
Objective
To observe the macular morphology and circumpapillary retinal nerve fiber layer thickness (RNFL) in Parkinson's disease (PD) evaluated by spectral-domain optical coherence tomography (SD-OCT).
Methods
A total of 37 patients (74 eyes) with PD were in the PD group, 32 age- and sex-matched healthy subjects (64 eyes) in the control group. All subjects underwent SD-OCT examination with 5 line scanning, macular cube 512×128 scanning and optic disc volume 200×200 scanning. The retinal thickness, central foveal thickness (CFT), macular volume and thickness of circumpapillary, superior, inferior, nasal, and temporal of RNFL between two groups were comparatively analyzed. The relationship between SD-OCT parameters and age, disease duration, scores of Hoehn-Yahr and unified PD rating scale (UPDRS) Ⅲ in PD patients was analyzed by Pearson correlation analysis.
Results
Both of the retinal thickness and macular volume in PD group were significantly reduced than those in control group (t= ?2.546, ?3.410;P=0.012, 0.001). There was no difference of CFT (t= ?0.463,P=0.644) and the thickness of circumpapillary (t= ?1.645,P=0.102), superior (t= ?0.775,P=0.439), inferior (t=?1.844,P=0.067), nasal (t= ?0.344,P=0.732) and temporal (t= ?0.541,P=0.590) of RNFL between two groups. The retinal thickness, macular volume, CFT and the thickness of circumpapillary, superior, inferior, nasal, temporal of RNFL had no relationship with age, disease duration and scores of Hoehn-Yahr and UPDRS Ⅲ in PD patients (P＞0.05).
Conclusions
In PD patients, the retinal thickness and macular volume are decreased, however, the circumpapillary RNFL have no obvious alterations.
At present, the incidence of Parkinson’s disease (PD) is gradually increasing. This seriously affects the quality of life of patients, and the burden of diagnosis and treatment is increasing. However, the disease is difficult to intervene in early stage as early monitoring means are limited. Aiming to find an effective biomarker of PD, this work extracted correlation between each pair of electroencephalogram (EEG) channels for each frequency band using weighted symbolic mutual information and k-means clustering. The results showed that State1 of Beta frequency band (P = 0.034) and State5 of Gamma frequency band (P = 0.010) could be used to differentiate health controls and off-medication Parkinson’s disease patients. These findings indicated that there were significant differences in the resting channel-wise correlation states between PD patients and healthy subjects. However, no significant differences were found between PD-on and PD-off patients, and between PD-on patients and healthy controls. This may provide a clinical diagnosis reference for Parkinson’s disease.
