RESUMEN
Parkinson's disease (PD) is a common degenerative neurological disease in middle-aged and elderly people,which is characterized by typical motor symptoms.The accompanying non-motor symptoms are also getting increasingly attention.Among them,psychosis associated with Parkinson's disease accounted for 30％-80％ of patients with Parkinson~ disease,mainly in PD patients treated for 10 years or more,and the severity of mental symptoms have a greater impact on the quality of life of patients.This article provides a brief review of the current state of drug treatment for psychosis associated with Parkinson's disease (PDPs).
RESUMEN
Objective o investigate the clinical characteristics and relevant risk factors of freezing gait in patients with Parkinson's disease (PD).Methods A total of 570 consecutive PD patients were registered basic information and evaluated by Unified Parkinson's Disease Rating Scale (UPDRS) and New Freezing of gait questionnaire (NFOG-Q).They were divided into the PD with freezing gait group (188 cases) and non-freezing gait group.Results UPDRS score in each part (UPDRS-Ⅰ,UPDRS-Ⅱ,UPDRS-Ⅲ,UPDRS-Ⅳ) and Hoehn & Yahr stage of the PD freezing gait group was significantly higher than that of the non frozen gait group (P ＜ 0.05).Conclusions PD patients with frozen gait group experience more rapid PD progression than those without freezing of gait.The appearance of FOG is associated with the mental behavior and emotion,treatment complication,disease severity,and course of PD.
RESUMEN
Weight loss is common in non-motor symptoms in Parkinson disease (PD).It may predate motor symptom onset,and may be associated with the development of disease.However,it was less accounted of clinically.The pathophysiology of weight loss in PD is very complicated.This review discusses the pathogenesis of PD weight loss from dopaminergic dysfunction,energy expenditure/intake imbalance,central mechanisms of feeding behavior regulation,and neuroendocrine abnormalities.
RESUMEN
Objective To investigate the prevalence of fatigue symptoms and investigate its related factors in patients with Parkinson's disease (PD).Methods The Parkinson's Fatigue Scale (PFS-16) was used to assess the fatigue status of 453 PD patients.These patients were divided into fatigue group (mean PFS-16≥3.3 defined as fatigue) and non-fatigue group.All of them completed the assessment of the relevant scale.Results Among 453 PD patients,there were 169 patients (37.3％) in fatigue group and 284 patients (62.7％) in non-fatigue group.Unified Parkinson's disease Rating Scale (UPDRS) and HoehnYahr (H-Y) staging in fatigue group were significantly higher than non-fatigue group (P ＜0.05).Motor symptoms,mental and emotional status and daily living ability are positively correlated with fatigue symptoms.Conclusions The motor symptoms and non-motor symptoms are more serious in PD patients with fatigue.The motor symptoms,mental and emotional status,daily living ability and Hoehn-Yahr (H-Y) stage are the main related factors of fatigue symptoms in PD patients.
RESUMEN
Objective To explore the correlated factors and clinical features of cognitive impariment in parkinson's disease (PD).Methods A total of 419 patients with PD were collected from Xiangya Hospital of Centre-South University during Mar 1st,2017 to Nov 30th,2017.The cognitive functions of patients were assessed with the Mini-Mental State Examination (MMSE),and the basic information and the motor symptoms of 419 PD patients were selected at the same time.The PD patients were classified into three groups according to the MMSE score:PD with no cognitive impairment (PD-NC),mild cognitive impairment in PD (PD-MCI),and Dementia in PD (PD-D).The data were analyzed by SPSS 20.0.Results There were 156 patients with PD-MCI (37.2％) and 64 patients with PD-D (15.3％).The difference of sex and disease duration among three groups were not statistically significant (P ＞ 0.05).The significant difference was found among PD-D,PD-MCI,and PD-NC groups in age of onset,age,educational attainment,Unified Parkinson's disease Rating Scale (UPDRS)-Ⅱ score,UPDRS-Ⅲ score and Hoehn-Yahr stage (P ＜ 0.05).There were significant differences among three groups in MMSE score and its items (P ＜ 0.01).Logistics regression analysis found that the age of onset,educational attainment,and Hoehn-Yahr stage were the risk factors of cognitive impairment in PD patients (P ＜ 0.05).Conclusions Cognitive impairment is common in PD patients,and it is relevant to the age of onset,educational attainment and the severity of illness of PD patients.
RESUMEN
Objective To investigate the change of body mass index (BMI) in Parkinson's disease (PD) and its association with disease severity.Methods SPSS 22.0 was used for data analysis of one hundred and sixty-eight PD patients and one hundred and fifteen healthy controls.Results BMI value was obviously declined in PD (P =0.001).Decrease of BMI in PD was associated with increase of disease duration (r =-0.270,P =0.001),total score of Unified Parkinson~ Disease Rating Scale (UPDRS) (r =-0.195,P =0.008),score of UPDRS part Ⅱ (r =-0.147,P =0.045),score of UPDRS part Ⅲ (r =-0.159,P =0.030),H-Y grading (r =-0.256,P =0.001),and mini-mental state examination (MMSE) (r =0.291,P =O.001).Conclusions BMI declines more obviously in PD patients than in healthy controls.PD Patients with longer disease duration and severe motor symptoms have a higher risk of BMI loss.
RESUMEN
Objective To investigate the clinical features of constipation in patients with Parkinson 's disease (PD) and explore the relationship between constipation and motor symptoms.Methods The data of 221 PD patients were collected.Patients were evaluated with following scales:Rome Ⅲ criteria for diagnosis of functional constipation,unified Parkinson's disease rating scale part Ⅲ (UPDRS Ⅲ),and simple mental status examination scale (MMSE).Results Among 221 PD patients,132 (59.7％) had constipation,and 48 (36.4％) experienced constipation before motor symptoms.Compared to those without constipation,PD patients with constipation had a higher UPDRS Ⅲ scores,posture/gait scores,and axis scores (P ＜ O.05).The most common symptoms of PD patients with constipation were defecation straining (93.9％).Conclusions PD patients with constipation have severer motor symptoms than those without constipation.Defecation straining is the most common subtypes of PD patients with constipation.
RESUMEN
Parkinson disease (PD) is a common neurodegenerative disease,of which clinical symptoms give priority to movement disorders,accompanied by a series of non-motor symptoms,such as pain.Studies suggest that 40％ to 85％ of PD patients combined with pain,of more nature is related to muscleskeletal and dystonia.PD combined with pain severely reduces the quality of life of patients.However,it is still lack of uniform clinical evaluation and effective treatment.This paper makes a brief overview about the status and research progress of the evaluation and treatment of PD combined with pain.
RESUMEN
Objective To investigate the anxious behavior in acute parkinson's mice that were induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) injection.Methods Twenty mice were randomly divided into the control group (n =10) and model group(n =10);The model group was induced by injecting MPTP dosage,and the control group was induced by the same dose of saline.The anxious behaviors in mice were tested by the elevated plus-maze test and the light/dark box.Results The model group mice spent a longer time than the control group in the dark box (P ＜ 0.05).The open arm entry (OE),open arm time (OT) and OE％ of model group was significantly less than that in control group in the elevated plus-maze test (P ＜ 0.01),the OT％ was significantly less than control group (P ＜0.05).Conclusions Anxiety symptoms appeared in the model group of early parkinson disease (PD)mice.
