Clinical heterogeneity and cluster analysis of multiple system atrophy / 中华老年医学杂志

Objective:To examine the clinical subtypes of patients with multisystem atrophy(MSA)that may indicate the prognosis of patients.Additionally, we aim to compare the ability to perform daily activities among patients of each subtype using cluster analysis.Methods:The retrospective analysis included demographic data, clinical symptoms and signs, scale scores, and ancillary examinations of 94 patients diagnosed with multisystem atrophy at Xuanwu Hospital of Capital Medical University.The study aimed to analyze the clinical characteristics of each subtype obtained through clustering.Additionally, a comparison was made between patients with traditional motor subtypes and those with new subtypes in terms of activities of daily living.The study consisted of 94 MSA patients, with an average age of 61 years and a female representation of 51.1%.Using the data collected on the continuum, a full linkage hierarchical cluster analysis was performed to classify MSA patients into four clinical subtypes: gait disorder(17 cases, 18.1%), malignant tonic hyperkinetic with premature haircut(25 cases, 26.6%), intermediate(43 cases, 45.7%), and autonomic benign type(9 cases, 9.6%).Each subtype exhibited various clinical motor and non-motor symptoms, including UPDRS-Ⅲ( χ2=27.90, P<0.001), gait disturbance( χ2=33.23, P<0.001), MoCA( χ2=10.98, P=0.012), HAMA( χ2=12.14, P=0.007), HAMD( χ2=13.62, P=0.003), smell score( χ2=10.16, P=0.017), postural hypotension( χ2=14.59, P=0.028), and a statistically significant difference in the ability to perform daily living score( χ2=25.35, P<0.001).No statistically significant differences in non-motor symptoms and activities of daily living abilities were observed between the cerebellar and Parkinsonian types of traditional motor typing( P>0.05). Conclusions:The hierarchical clustering analysis conducted in this study reveals that the clinical phenotype of MSA provides a more accurate reflection of patients' clinical characteristics and their impact on quality of life compared to the traditional motor phenotype.Additionally, it may help predict variations in the underlying pathological impairment and the rate of disease progression.These findings offer a foundation for precise diagnostic interventions in patients with MSA.

Research progress on non motor symptoms of multiple system atrophy / 中国医师杂志

Multiple system atrophy (MSA) is a rapidly developing and serious Degenerative disease of the nervous system. It is characterized by different combinations of prominent autonomic dysfunction, Parkinson′s syndrome and cerebellar Ataxia in clinical practice, and its core symptom is extensive and serious autonomic dysfunction in the early stage of the disease. Non motor symptoms of MSA involve nervous system, cardiovascular system, gastrointestinal system, Genitourinary system and many other fields. Early clinical heterogeneity is large. This article describes the non motor symptoms of MSA, including prodromal symptoms, to help clinicians identify MSA earlier.

Factors affecting health-related quality of life in patients with Parkinson's disease / 中风与神经疾病杂志

@#Objective Our objective was to identify factors predicting health-related quality of life (HRQoL) in patients with Parkinson's disease (PD) Methods A cross-sectional study was carried out in 161 PD patients. QoL was assessed with the PDQ-39.Motor symptoms and non-motor symptoms were evaluated by a list of assessment tools including the Hoehn and Yahr scale,The Movement Disorder Society Unified Parkinson Disease Rating Scale et al. The Spearman correlation coefficient r was used to evaluate the correlation between PDQ-39 and motor and non-motor factors. Multiple linear regression models were used to demonstrate whether the factors investigated contribute significantly to QoL. Results PDQ-39 Summary Index was highly correlated with Voice handicap index(r=0.616) and correlated at a moderate level (r=0.30-0.50) with UPDRS-I,UPDRS-II,Parkinson Fatigue Scale,Modified Apathy Evaluation Scale,Geriatric Depression Scale,Gait and Falls Questionnaire,Eating Assessment Tool Scale. Depression,gait,swallowing,voice handicap and gender were independent predictors of HRQoL in the multivariate analysis model. Depression showed to be the most consistent determinant of HRQoL,followed by gait problems,swallowing,voice handicap and gender. Conclusion Depression,gait problems,swallowing,voice handicap and gender are significant factors contributing to a poor quality of life in Parkinson's disease patients. Swallowing and voice handicap,as well as depression,gait problems that are widely recognized,are also factors that cannot be ignored.

Effect of cognitive behavioral therapy on quality of life in patients with Parkinson's disease： a Meta-analysis / 四川精神卫生

BackgroundDepression， anxiety， impulse control disorders， insomnia are prevalent non-motor symptoms of Parkinson's disease， severely impairing the quality of life of patients. Cognitive behavioral therapy （CBT） is a common psychological intervention for various clinical psychological conditions， which can improve anxiety， insomnia and depression in patients with Parkinson's disease. However， the current research evidence on the effects of CBT in improving quality of life in patients with Parkinson's disease remains inconsistent. ObjectiveTo assess the effects of CBT on the quality of life among patients with Parkinson's disease， so as to provide references for the clinical application of CBT in this population. MethodsOn May 25， 2023， a systematic search was conducted across PubMed， PsycINFO， Embase， CNKI， Wanfang Database and VIP Database to identify randomized controlled trials investigating the impact of CBT on the quality of life in patients with Parkinson's disease. Literature screening， quality evaluation and data extraction were performed， focusing on variables related to quality of life， anxiety， and depression. Meta-analysis was performed using Stata 13.0 and RevMan 5.3. ResultsA total of 11 studies with 456 participants were included， comprising 241 in the CBT group and 215 in the control group. The CBT group exhibited significantly higher quality of life compared with the control group （SMD=0.47， 95% CI： 0.27~0.67， P<0.01）. Anxiety and depression scores in CBT group were significantly lower than those in the control group （SMD=-0.63，95% CI：-0.84~-0.43， P<0.01； SMD=-0.83， 95% CI： -1.15~-0.51， P<0.01）. Among the 11 studies， 6 studies delivered CBT remotely and 5 studies implemented CBT face-to-face. Meta-analysis results revealed that remote CBT group yielded significantly higher quality of life （SMD=0.43， 95% CI： 0.17~0.70， P<0.01）， and lower anxiety and depression scores （SMD=-0.62， 95% CI： -0.91~-0.34， P<0.01； SMD=-0.78， 95% CI： -1.34~-0.21， P<0.01） compared with the control group. Similarly， face-to-face CBT group showed better outcomes than the control group in terms of quality of life， anxiety and depression （SMD=0.51， 95% CI： 0.22~0.81， P<0.01； SMD=-0.64， 95% CI： -0.93~-0.35， P<0.01； SMD=-0.90， 95% CI： -1.20~-0.60， P<0.01）. ConclusionCBT may contribute to alleviating anxiety and depression levels of patients with Parkinson's disease， and improving their quality of life.｛Funded by Shanghai 13th Five-Year Key Specialty Construction Project （number， shslczdzk04901）； Nature Fund Project of Shanghai Science and Technology Commission （number， 22ZR1459300）； Shanghai Municipal Health Commission Traditional Chinese Medical Science Non-drug Therapy Demonstration Center Project ［number， ZY（2021-2023） -0204-03］｝

Characteristics of motor and non-motor symptoms in patients with rapid eye movement sleep behavior disorder and early Parkinson disease / 中华行为医学与脑科学杂志

Objective:To investigate the motor and non-motor symptoms and polysomnographic features in patients with rapid eye movement sleep behavior disorder (RBD), early Parkinson's disease (PD) with and without RBD.Methods:Patients with idiopathic RBD (IRBD) and early PD were collected from the clinics in West China Hospital of Sichuan University from August 2020 to May 2021.All the patients were divided into 3 groups including IRBD group (67 cases), PD with RBD (PD+ RBD) group (19 cases), and PD without RBD (PD-RBD) group (22 cases). Unified Parkinson's disease rating scale part 3 (UPDRS-Ⅲ), Hoehn-Yahr(H-Y) stage, Epworth sleepiness scale (ESS), REM sleep behavior disorder questionnaire-Hong Kong (RBDQ-HK), 17-item Hamilton depression scale(HAMD-17), mini-mental state examination(MMSE), Sniffin’Sticks olfactory function test, visual analogue scale (VAS), and scale for outcomes in Parkinson's disease-AUT(SCOPA-AUT) were used to assess the motor and non-motor symptoms including sleepiness, RBD, depression, cognitive function, olfactory function, pain and autonomic function respectively.All patients were performed to the polysomnography (PSG) examination.One-way ANOVA, Krukal-Wallis test, χ2 test and Fisher accurate test were used to analyze the data of motor and non-motor symptoms and sleep parameters among the 3 groups accordingly. Results:There were statistically significant differences in motor symptoms among the three groups ( F=57.009, P<0.05), and the scores of UPDRS Ⅲ and H-Y stage were higher in the PD+ /- RBD group than those in the IRBD group(both P<0.05). However, there was no significant difference in motor symptoms between PD+ RBD group and PD-RBD group ( P>0.05). There were no significant differences in the scores of ESS, MMSE, olfactory function test and VAS (all P>0.05). But the HAMD-17 score was significantly higher in the PD+ RBD group(2(1, 9)) than that in the IRBD group (0(0, 3)( P<0.05). The SCOPA-AUT scores of autonomic function were significant differences in the three groups, mainly in the digestive system, urinary system, and sexual function ( P<0.05). Notably, the IRBD group (8(4, 14)) and PD+ RBD group (11(7, 14)) had higher scores of SCOPA-AUT compared with PD-RBD group (4(4, 5.75)(all P<0.05), especially in the digestive dysfunction(all P<0.05). The PD+ RBD group(3.47±1.17) had higher scores of sexual function compared with IRBP group(1.78±0.60)( P<0.05), and the urinary system scores also higher than PD-RBD group( P<0.05). The PD-RBD group(21.30 (6.10, 34.00)/h) had a significantly higher oxygen desaturation index in REM sleep compared with that of IRBD group(5.90(2.70, 16.73)/h) ( P<0.05). Conclusions:Early PD with RBD has more severe non-motor symptoms, especially depression and autonomic dysfunction.RBD can be related with the earlier and more widely autonomic dysfunction.

Analysis of clinical features of mild motor symptoms in prodromal Parkinson′s disease / 中华神经科杂志

Objective:To investigate the characteristics and evolution of mild motor symptoms (MMS) in patients with prodromal Parkinson′s disease (pPD).Methods:Based on the pPD cohort screened by Parkinson′s Disease Prodromal Clinical Assessment Scale in Nanjing community from July 2018 to December 2020, the clinical data of 30 patients with pPD who completed the baseline assessment and were followed up for at least 1 year were analyzed. According to the Unified Parkinson Diease Rating Scale Ⅲ (UPDRS-Ⅲ) score, the patients were divided into MMS group (UPDRS-Ⅲ score>3) and non-MMS group (NMMS group, UPDRS-Ⅲ score≤3). The differences and evolution characteristics of clinical characteristics between the 2 groups were compared. Multivariate linear regression was used to analyze the risk factors of motor symptom progression in pPD patients.Results:Among the 30 patients with pPD, 7 of 23 patients in the MMS group were converted to PD at the end of follow-up, 1 of 7 patients in the NMMS group were converted to PD at the end of follow-up. The UPDRS-Ⅲ score [10.00 (7.00, 17.00)], Montreal Cognitive Assessment Scale (MoCA) score [25.50 (24.75, 28.00)] and the Hamilton Anxiety Scale (HAMA) score [9.00 (5.00, 13.00)] at the end of follow-up of pPD patients were significantly higher than those at baseline [7.00 (4.00, 12.00), 24.00 (22.75, 25.25) and 8.00 (2.00, 11.00)], and the differences were statistically significant ( Z=-3.505, P<0.001; Z=-2.956, P=0.003; Z=-2.427, P=0.015).Subgroup analysis showed that UPDRS-Ⅲ score [11.00 (7.00, 18.00)], MoCA score [25.00 (24.00, 27.00)] and HAMA score [ 9.00 (6.00, 15.00)] at the end of follow-up in the MMS group were higher than those at baseline [8.00 (6.00, 12.00), 24.00 (22.00, 25.00) and 9.00 (3.00, 11.00)], and the difference was statistically significant (Z=-2.768, P=0.006; Z=-2.457, P=0.014; Z=-2.250, P=0.024). The Non-Motor Symptoms Questionnaire score at the end of follow-up in the MMS group (8.96±5.20) was significantly lower than that in the baseline (11.04±4.41), and the difference was statistically significant ( t=2.441, P=0.023).There was no significant difference in Mini-Mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Rapid Eyes Movement Sleep Behavior Disorder Questionnaire-Hong Kong (RBDQ-HK) and Sniffin′ sticks olfactory test score at the end of follow-up in the MMS group. Only UPDRS-Ⅲ score in the NMMS group was increased at the end of follow-up [7.00 (5.00, 8.00)] compared with the baseline [4.00 (1.00, 4.00)], and the difference was statistically significant ( Z=-2.375, P=0.018). There was no significant difference in MoCA, MMSE, HAMA, HAMD, RBDQ-HK, and Sniffin′ sticks olfactory test score between the NMMS group and the baseline at the end of follow-up. Conclusion:The clinical conversion rate of pPD patients with MMS is high,and screening of this population should be paid attention.

The characteristics and gender differences of non-motor symptoms in early diagnosed Parkinson’s disease / 中风与神经疾病杂志

@#To explore the characteristics and gender differences of non-motor symptoms（NMS） in De Novo Parkinson’s diseases （PD）. Methods 203 newly diagnosed PD patients （102 males，101 females） and 255 healthy controls （110 males，145 females） were selected. The clinical data were collected and evaluated by mini-mental State Examination （MMSE），Montreal Cognitive Assessment （MoCA），Hamilton Depression Scale （HAMD），Hamilton Anxiety Scale （HAMA），Parkinson’s disease Sleep Scale （PDSS），Unified PD Rating Scale Part III （UPDRS-III） and Hoehn Yahr （H-Y） stage. Non-motor questionnaire screening scale （NMSQ） was used to assess their non-motor symptoms，and compared the characteristics of NMS in different genders. Multivariate linear regression was used to analyze the influencing factors of NMDQ score in PD patients. Results 98.5% of PD patients had at least one NMS，among which forgetfulness （ 67.5%），depression （49.8%） were the most common. The total score and nine domains of NMS in PD group were significantly higher than those in healthy controls （all P<0.05）. The rates of interest decline，depression，anxiety and excessive sweating in female in PD group were significantly higher than those in male，while the rate of dysphagia was significantly lower （all P<0.05）. The rates of hallucination and sweating increase in female in healthy controls were significantly higher than those inmale，the rate of memory decline was significantly lower （all P<0.05）. The total scores of NMS in male and female patients with PD were affected by HAMD and PDSS （all P<0.05），while male patients were more likely to be affected by the disease duration （β= 0.181，P=0.032）. Conclusion The incidence of non motor symptoms in newly diagnosed PD patients is significantly higher than that in healthy controls and different in gender.

Effects of binary dance rhythm compared with quaternary dance rhythm in fatigue, sleep, and daily sleepiness of individuals with Parkinson's disease: A randomized clinical trial

Abstract Aim: People with Parkinson's disease constantly demonstrate low levels of physical activity, which is why dance has become increasingly important for the treatment of the disease. This study aimed to analyze the influence of binary and quaternary rhythm on fatigue, sleep, and daytime sleepiness in individuals with Parkinson's disease. Methods: 31 individuals participated in this randomized clinical trial with a mean age of 66.6 ± 10.2 years, 71% were male and 29% were female, allocated into two groups, binary and quaternary, where they participated in different dance interventions lasting 12 weeks. A questionnaire was applied including personal and clinical information; Mental State Mini-Examination (MMSE), Hoehn and Yahr (H&Y), Fatigue Severity Scale (FSS), Sleep Scale for Parkinson's Disease (PDSS), and Daytime Sleepiness Epworth Scale (ESS). Results: The groups that participated in binary rhythm classes showed improvement in sleep quality and daytime sleepiness after 12 weeks of intervention. However, no significant differences were found in the group that participated in the quaternary rhythm classes. Moreover, it was noted that the binary group managed to raise the heart rate during the 12 weeks of intervention, given that these results were not obtained in the quaternary group. Conclusion: The results showed the effectiveness of binary rhythm on non-motor symptoms and heart rate increase in individuals with Parkinson's disease. Thus, it is concluded that the binary rhythm was more effective than the quaternary rhythm.

Effects of Baduanjin and Balancer Exercise on Motor and Non-motor Symptoms of Parkinson's Disease / 中国康复理论与实践

Objective:To explore the effects of Baduanjin and balancer exercise on motor and non-motor symptoms for patients with mild to moderate Parkinson's disease (PD). Methods:From May, 2017 to September, 2018, 31 patients with PD were collected from the inpatients, outpatients and outside of our hospitals. The patients accepted Baduanjin and balancer exercise successively, three weeks for each exercise, and were assessed with Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part I, II, III and IV, and Non-motor Symptoms Scale (NMSS) before and after each exercise. Results:Four cases dropped out during Baduanjin exercise. The total score, the scores of part I, II and III of MDS-UPDRS, and NMSS score (t > 3.274, P < 0.01) decreased significantly after Baduanjin exercise. Other three cases dropped out during balancer exercise. The total score and the score of part III of MDS-UPDRS decreased significantly after balancer exercise (t > 2.763, P < 0.05). Conclusion:Baduanjin exercise can improve the motor and non-motor symptoms of mild to moderate PD, but not significant for motor complications; while balancer exercise can improve the motor symptoms, but not significant for non-motor symptoms and motor complications.

The impact of brazilian samba on parkinson's disease: analysis by the disease subtypes / O impacto do samba brasileiro na doença de parkinson: análise através dos subtipos da doença / El impacto del samba brasileño en la enfermedad de parkinson: análisis a través de los subtipos de la enfermedad

ABSTRACT Introduction: People with Parkinson's disease constantly have low levels of physical activity. Dancing has become increasingly important for treating the disease and can help improve non-motor symptoms. Objective: To analyze the influence of Brazilian samba on the non-motor symptoms of PD according to TD and PGID subtypes. Methods: A 12-week, non-randomized clinical trial, through comparison with a control group. The 23 individuals who agreed to participate in the activities formed the experimental group (EG) and the 24 individuals who opted not to participate in the Brazilian samba classes comprised the control group (CG). A questionnaire was applied, composed of validated instruments. Mini Mental State Examination - MMSE; HY - Disability Scale; Unified Parkinson's Disease Rating Scale - UPDRS 1 and total values; Parkinson's Disease Questionnaire - PDQ-39, Parkinson's Disease Sleep Scale - PDSS; Beck Depression Inventory - BDI; Fatigue Severity Scale - FSS and Magnitude of Perceived Changes. Results: After the twelve weeks of intervention, it was observed that the EG showed improvement in the scores of all the tests. The comparison between groups, however, indicated a significant difference in the post-UPDRS1 period in which the EG presented improvement in cognitive impairment, while the CG presented a deficit in these values. The results of the division between disease subtypes show a greater change in the values between individuals of the TD group, when comparing the EG with the CG. For the EG, the greatest difference between pre- and post- intervention was fatigue. Conclusion: There was a positive trend in all the variables studied after the application of the protocol. This demonstrates that interventions such as dance may have greater effects on non-motor symptoms, depending on the expected progression of the disease. The scarcity of studies that use this approach in their analyses may explain the lack of evidence in this symptomatology related to dance.

RESUMO Introdução: As pessoas com doença de Parkinson constantemente apresentam baixos níveis de atividade física. A dança tem se tornado cada vez mais importante para o tratamento da doença e pode ajudar a melhorar os sintomas não motores. Objetivo: Analisar a influência do samba brasileiro nos sintomas não motores da DP, segundo os subtipos TD e PGID. Métodos: Ensaio clínico não randomizado com duração de 12 semanas por meio de comparação com grupo controle. Os 23 indivíduos que aceitaram participar das atividades formaram o grupo experimental (GE) e os 24 indivíduos que optaram por não participar das aulas de dança brasileira formaram o grupo controle (GC). Um questionário foi aplicado, composto por instrumentos validados: Mini Exame do Estado Mental - MEEM; HY - Escala de Grau de Incapacidade; Escala Unificada de Avaliação da Doença de Parkinson - UPDRS 1 e valores totais; Questionário sobre a Doença de Parkinson - PDQ-39; Escala de Sono para a Doença de Parkinson - PDSS; Inventário de Depressão de Beck - BDI; Escala de Severidade de Fadiga - FSS e Magnitude das Alterações Percebidas. Resultados: Após doze semanas de intervenção, observou-se que o GE apresentou melhora nos escores de todos os testes. A comparação entre os grupos, no entanto, indicou uma diferença significativa no período pós-UPDRS1 em que o GE apresentou melhora no comprometimento cognitivo, enquanto o GC apresentou déficit nesses valores. Os resultados da divisão entre os subtipos da doença apresentam uma maior mudança nos valores entre os indivíduos do grupo TD ao comparar o GE com o GC. Em relação ao GE, a maior diferença entre a pré e pós-intervenção foi relacionada à fadiga. Conclusão: Houve tendência positiva em todas as variáveis estudadas após a aplicação do protocolo. Isso demonstra que intervenções como a dança podem ter maiores efeitos sobre os sintomas não motores, dependendo da progressão esperada da doença. A escassez de estudos que utilizam essa abordagem em suas análises pode explicar a falta de evidências nessa sintomatologia relacionadas à dança. Nível de evidência II; Estudos terapêuticos-Investigação dos resultados do tratamento.

RESUMEN Introducción: Las personas con enfermedad de Parkinson constantemente presentan bajos niveles de actividad física. La danza se ha vuelto cada vez más importante para el tratamiento de la enfermedad y puede ayudar a mejorar los síntomas no motores. Objetivo: Analizar la influencia del samba brasileño en los síntomas no motores de la EP, según los subtipos TD y PGID. Métodos: Ensayo clínico no aleatorizado con duración de 12 semanas, por medio de comparación con grupo control. Los 23 individuos que aceptaron participar en las actividades formaron el grupo experimental (GE) y los 24 individuos que optaron por no participar en las clases de danza brasileña formaron el grupo control (GC). Fue aplicado un cuestionario, compuesto por instrumentos validados: Mini Examen del Estado Mental - MEEM; HY - Escala del Grado de Incapacidad; Escala unificada de evaluación de la Enfermedad de Parkinson - UPDRS 1 y valores totales; Cuestionario sobre la Enfermedad de Parkinson - PDQ-39; Escala de Sueño de la Enfermedad de Parkinson - PDSS; Inventario de Depresión de Beck - BDI; Escala de Severidad de la Fatiga - FSS y Magnitud de las Alteraciones Percibidas. Resultados: Después de doce semanas de intervención, se observó que el GE presentó una mejora en los puntajes de todos los tests. La comparación entre los grupos, sin embargo, indicó una diferencia significativa en el período post-UPDRS1 en que el GE presentó una mejora en el compromiso cognitivo, mientras que el GC presentó déficit en esos valores. Los resultados de la división entre los subtipos de la enfermedad presentan un mayor cambio en los valores entre los individuos del grupo TD al comparar el GE con el GC. Con relación al GE, la mayor diferencia encontrada entre la pre y post intervención fue relacionada a la fatiga. Conclusión: Hubo tendencia positiva en todas las variables estudiadas después de la aplicación del protocolo. Eso demuestra que intervenciones como la danza pueden tener mayores efectos sobre los síntomas no motores, dependiendo de la progresión esperada de la enfermedad. La escasez de estudios que utilizan ese abordaje en sus análisis, puede explicar la falta de evidencias en esa sintomatología cuando relacionadas a la danza.

Non-motor symptoms in amyotrophic lateral sclerosis / 西安交通大学学报(医学版)

Amyotrophic lateral sclerosis (ALS) is a degenerative disease of the nervous system caused by the loss of motor neurons in the brain and spinal cord. At present, ALS is considered as a multi-system disease, with both motor and non-motor features. Motor neuron involvement usually begins in a single functional region (medulla oblongata, cervical vertebra, lumbosacral and thoracic vertebra) and gradually spreads throughout the motor system. Non-motor features may be caused by pathological damage from the motor region to the adjacent non-motor region or by other unknown causes. There is no uniform definition of non-motor features of ALS. Sometimes they refer to symptoms caused by damage to the non-pyramidal system, and sometimes they also include ALS syndrome. They can be divided into neuropsychiatric, autonomic, vascular and gastrointestinal dysfunctions. More than 50% of patients with ALS have symptoms of neuropsychiatric disorder, which are extremely heterogeneous. Such clinical heterogeneity is based on neuroimaging, genetics and neuropathology, which has updated the concept of ALS, leading to the present recognition of the spectrum disorder of ALS and frontotemporal dementia. The core features of the ALS diagnosis model should also be multi-axis diagnosis, using three main "diagnostic axes", i.e., axis to define motor neuron symptom variations, axis Ⅱ to define cognitive and behavioral dysfunction, and axis III to define other non-motor symptoms. This paper introduces ALS cognitive and behavioral dysfunction, ALS plus syndrome and other non-motor features associated with ALS so as to improve clinicians' understanding of managing the overall health status of ALS patients, make rational scientific evidence-based decisions and contribute to improving the quality of life of ALS patients.

The Gender and Clinical Symptoms Difference in Depression of Parkinson’s Disease / 中风与神经疾病杂志

@#Objective　We aimed to analyze the gender differences by evaluating the motor and non-motor symptoms among the patients with parkinson’s disease and the patients with depression of parkinson’s disease，and to explore the possible pathogenesis further and make sex-specific therapeutic strategies. Methods　Two hundred patients with parkinson’s disease from both the outpatients department and the ward were included in this analysis. There were 56 patients whose HAMD scores exceeded 19，which were divided into the depession of parkinson’s disease （dPD） group。There are 144 patients whose HAMD scores under 20，which were divided into the non-depession of parkinson’s disease （ndPD） group. The scores from all the scales were analyzed using statistical software. Results　①The depression incidence of females was significantly higher than that of males in PD patients （P<0.05）. ②Rigidity score and Bradykinesia score in males were significantly higher than that in females in dPD patients （P<0.05）. Tremor score in males was significantly lower than that in females in dPD patients （P<0.05）. ③A significantly higher score in mood/apathy and feel problem/hallucination domains were observed in female PD patients （P<0.05）. ④The HAMA score，HAMD score，NMSQ total score of dPD patients were all significantly higher than that of ndPD patients （P<0.05）. The PDSS score of dPD patients was significantly lower than that of ndPD patients （P<0.05）. The tremor score，rigidity score，postural instability score，bradykinesia score，UPDRS-III score of dPD patients were all significantly higher than that of ndPD patients （P<0.05）. ⑤The HAMD scores correlated with levodopa equivalent doses （Led） （r=-0.31，P=0.01），H-Y stage （r=0.23，P=0.03），PDSS （r=0.36，P=0.01） and rigidity （r=0.27，P=0.04） scores. Conclusion　①There are gender differences bewteen males and females in motor disorders in depression of parkinson’s disease. ②The motor disorders and non-motor disorders were more severe in depression of parkinson’s disease than in non-depression of parkinson’s disease. ③The HAMD score in depression of parkinson’s disease correlated with levodopa equivalent doses，the motor disorders and the non-motor disorders. ④The spectrum of motor and non-motor symptoms showed different gender distribution in PD and dPD patients. Gender-specific therapeutic agents hold particula attention for developing treatments with optimal efficaty in men and women in the future.

Diagnósticos fonoaudiológicos y síntomas no motores en pacientes con Enfermedad de Parkinson / Phonoaudiological diagnoses and non-motor symptoms in patients with Parkinson's disease

Objetivo: Este estudio descriptivo se orientó a conocer el perfil clínico-epidemiológico de la Enfermedad de Parkinson (EP) y la coexistencia entre síntomas no motores (SNM) y diagnósticos fonoaudiológicos (DF). Método: La muestra estuvo conformada por 34 personas con Parkinson idiopático (26 hombres y 8 mujeres), cuyas historias clínicas fueron analizadas para describir la coexistencia de DF, como la hipofonía, la disprosodia, la disartria y la disfagia, con síntomas no motores, tales como: trastornos gastrointestinales, depresión, trastornos del sueño y deterioro cognitivo. Resultados: Los resultados señalan que las personas con Parkinson tenían edades entre los 25 a los 86 años. En cuanto a la fase, se clasificaron en: estadio I el 11,7%, II el 17,6%, III el 47%, IV el 14,7% y V el 8,8%. El 47% de los pacientes llegó al servicio de Fonoaudiología en una etapa avanzada de la EP. Los SNM más frecuentes fueron trastornos del sueño (67,6%), depresión (58,8%), alteraciones gastrointestinales (29,4%) y deterioro cognitivo (15%). Los DF se distribuyeron así: disprosodia (38%), hipofonía (33%), disartria (18%) y disfagia (11%). Discusión: se observa una alta frecuencia tanto de SNM (como la depresión y los trastornos del sueño), como de SF (especialmente disprosodia e hipofonía). Esta sintomatología provoca, por una parte, la reducción del deseo de relacionarse socialmente y por otro, dificultades para hacerse entender al presentar un volumen de voz reducido o prosodia (además de trastornos de la melodía, inflexiones, marcadores paralingüísticos) de la expresión oral del lenguaje. Conclusión: los trastornos del sueño y la depresión podrían tener un impacto negativo significativo en las funciones fonoaudiológico de las personas con Parkinson.

Objective: This descriptive study was aimed at understanding the clinical-epidemiological profile of Parkinson's disease (PD) and the coexistence between non-motor symptoms (NMS) and phonoaudiological diagnoses (PD). Methods: The sample comprised 34 people with idiopathic Parkinson's (26 men and 8 women). Their clinical histories were analysed to describe the coexistence of PD, such as hypophonia, dysprosody, dysarthria and dysphagia, with non-motor symptoms, such as gastrointestinal disorders, depression, sleep disorders and cognitive impairment. Results: The results indicate that people with Parkinson's are between the ages of 25 and 86. In terms of phase, they were classified as: stage I 11.7%, II 17.6%, III 47%, IV 14.7% and V 8.8%. 47% of patients reached the Speech Therapy service at an advanced stage of PD. The most frequent NMS were sleep disorders (67.6%), depression (58.8%), gastrointestinal disorders (29.4%) and cognitive impairment (15%). The PD were distributed as follows: dysprosody (38%), hypophonia (33%), dysarthria (18%) and dysphagia (11%). Discussion: a high frequency of both NMS (such as depression and sleep disorders) and PD (especially dysprosody and hypophonia) is observed. This symptomatology causes a reduction in the desire to relate socially, and difficulties in making oneself understood by presenting a reduced voice volume or prosody (in addition to melody of speech disorders, inflections, paralinguistic markers) of the oral language expression. Conclusion: sleep disorders and depression could have a significant negative impact on the speech and hearing functions of people with Parkinson's.

Effect of deep brain stimulation on Parkinson's disease non-motor symptoms / 中华神经科杂志

Deep brain stimulation (DBS) has been widely recognized for improving motor symptoms of Parkinson's disease,but its effect on non-motor symptoms is still unclear.This article reviews recent DBS-related studies and discusses the effects of DBS treatment on non-motor symptoms,including olfaction,depression,cognition,sleep,and pain.Current studies find that the impact of DBS on olfactory functions and depression is not clear.DBS may increase the suicide rate in postoperative patients,and the rising suicide rate could stem from the reduction of postoperative levodopa equivalent dosage.DBS shows no significant impairment on cognition,and postoperative cognitive decline of patients may result from the progression of Parkinson's disease.DBS may ameliorate insomnia,but could worsen restless legs syndrome and rapid eye movement sleep behavior disorder.In addition,DBS may help to relieve Parkinson's disease-related pain,but the mechanism of improvement is yet to be clarified.

Asymptomatic Hearing Impairment Frequently Occurs in Early-Onset Parkinson's Disease

OBJECTIVE: Recent reports of hearing impairment in Parkinson's disease (PD) have suggested that auditory dysfunction could be a non-motor manifestation of PD. These reports were based on observations of elderly patients for whom presbycusis may, to some extent, have contributed to hearing dysfunction. Therefore, we aimed to explore the auditory functions in younger patients with PD. METHODS: We conducted a case-control study in a relatively younger (< 55 years of age at study time) population of PD patients and healthy volunteers to test whether auditory dysfunction is a significant non-motor dysfunction in PD. Pure tone audiometry (PTA) and brainstem evoked response audiometry (BERA) were performed in all participants. RESULTS: None of the patients or controls reported hearing deficits. Fifty-one patients with PD and 50 healthy volunteers who were age- and gender-matched to the patients participated. PTA-detected hearing impairment was found in 64.7% of patients and 28% of controls (p < 0.001) for both low-mid and/or high frequencies. Hearing impairment was more frequent in the younger subgroups of patients than age-matched controls, while the frequency of hearing impairment was similar in older groups of subjects. BERA was not different between patients and controls. CONCLUSION: Asymptomatic auditory dysfunction is a common non-motor manifestation of early-onset PD and more frequent in younger patients, indicating that it may be independent of aging. The mechanism underlying this dysfunction appears to be peripheral, although a central dysfunction cannot be ruled out based on the findings of this study.

The clinical research progress of non?motor symptoms in myasthenia gravis / 中华神经科杂志

Myasthenia gravis (MG) is an acquired autoimmune disease involving neuromuscular junctions transmit dysfunction. The main clinical manifestations are partial or systemic skeletal muscle weakness and extreme fatigue, increased symptoms after activity, relieved after rest and treatment with cholinesterase inhibitors. However, recent studies have found that patients of MG are not only accompanied by motor symptoms such as muscle weakness and dysphagia, but also with non?motor symptoms. This article reviews the clinical research progress of non?motor symptoms in MG.

Depression in Parkinson's disease / 中国实用内科杂志

Parkinson's disease(PD) is a chronic progressive neurodegenerative disease. Its clinical manifestations include motor symptoms and non-motor symptoms. Many more researches have focused on non-motor symptoms, especially depression, which seriously affects the quality of life of PD, but in clinical practice, it is difficult to detect depression and get it treated properly. This review will present the situation of depression in PD, including etiology, diagnosis and treatment.
