ABSTRACT
Objective To study the characteristics and influencing factors of cognition on patients with Parkinson' s disease (PD) in Xi'an in order to provide evidence for early recognition and treatment of cognitive impairment on PD patients. Methods Clinically defined PD patients from 7 hospitals in Xi'an from Jan. to Apr. 2007 were assessed with mini-mental state examination (MMSE) and Montreal cognitive assessment (MOCA) for whole cognitive function. Furthermore,Fuld object memory test (FOM) was used to assess delayed memory while rapid verbal retrieve (RVR) was used to assess language fluency. Digit span subtest was used to assess attention and building blocks was used to assess visual space function respectively. Results 100 PD patients were recruited,including 52 men and 48 women,from 43 to 86 years old (65.6±17.1). MMSE scores was used as the standard for Recognition,PD with cognitive impairment accounted for 16%. According to MOCA scores,with PD cognitive disturbances accounted for 83%. Ability for calculation,short-term memory,visual space function,abstract capability,attention and language fluency dysfunction were main cognitive disturbances of PD. Analysis from single factor logistic regression showed that education,age of onset and gender were closely related to the occurrence of cognitive impairment on PD patients. Conclusion Cognitive impairment was common in PD. Ability of calculation,short-term memory,visual space function,abstract capability,attention and language fluency dysfunction were main cognitive disturbances of PD. Cognitive impairment of PD was more likely to occur with low degree of education,late onset of PD,and being female.
ABSTRACT
Objective To investigate the treatment status of antiparkinsonism in Xi'an. Methods Six general hospitals were randomly chosen in Xi' an and all Parkinson' s disease (PD) patients were interviewed by questionnaire from Jan. 2007 to Apr. 2007. Results 92 PD outpatients were enrolled in, including 48 males and 44 females, from 43 to 86 years old (mean 65.6±17.1) with duration of the disease from 0.2 to 27.8 years (mean 4.4 ±9.4). The preference of the drug use from the patients were: 40 (43.5%) preferred taking levodopa, 25 (27.2%) with amantadine and/or trihexyphenidyl, 14(15.2%) with levodopa and others, 4(4.4%) with dopamine agonist and others, 2 (2.2%) with other drugs, 7 (7.6%) with no treatment. There were 69 (75.0%) patients onset with resting tremor, 15 (16.3%) with bradykinesia, 6 (6.5%) with rigidity, and 2 (2.2%) with unknown symptoms. There was no startically significant difference in anti-PD drugs among the patients onset with different symptoms (P>0.05). 45 patients appeared the onset of disease before 65 years old and with no dementia, 47 onset after 65 with or without dementia. There was no significant difference of anti-PD drugs between the two groups (P>0.05). Most patients initiated anti-PD treatment with levodopa but few of them chose dopamine agonist. According to the classification of Hoehn & Yahr, 25(27.2%) belonged to Grade Ⅰ, 53(57.6%) to Grade Ⅱ ,8(8.7%) to Grade Ⅲ ,3(3.3%) to Grade Ⅳ and 3 (3.3%) to Grade Ⅴ. There was no significant differences of anti-PD drugs between different grades of the disease (P>0.05). 55.3% of the patients changed their anti-PD drugs randomly during the therapy, but with no relation to their gender, age, educational level, dementia, the number of family members, course of diseases, or the degree of Hoehn & Yahr, frequency and categories of medicine. Conclusion Anti-PD treatment in Xi' an did not strictly follow the standardized protocol, with few patients using dopamine agonist and over 50% of the patients changed their drugs randomly.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the incidence of dementia among elderly people in Xi'an and its related risk factors.</p><p><b>METHODS</b>Subjects that had been studied on the prevalence of dementia were follow-up, and the incidence of dementia, Alzheimer disease (AD) , and vascular dementia (VD) were counted by person-years. The clinical diagnosis on dementia,AD and VD were based upon the 3rd Edition of Diagnostic and Statistical of Manual of Mental Disorder, Revised version (DSM-III-R) and NINCDS-ADRDA criteria.</p><p><b>RESULTS</b>2197 subjects of non-dementia being identified in 1998, were re-surveyed in 2001. Out of them, 47 new cases of dementia including 37 cases of AD and 8 cases of VD were identified, with an annual incidence rates of dementia, AD and VD as 0.68%, 0.54% and 0.12% among those of 55 years and over and 0.89%, 0.69% and 0.17% in 65 years and over, respectively. Analysis from single factor logistic regression showed that age and education but not gender were closely related to the occurrence of AD. On the contrary, age, hypertension and stroke were closely related to the occurrence of VD.</p><p><b>CONCLUSION</b>The incidence of dementia in the "Xi' an cohort" was similar to that being reported from other countries. AD and VD were an age-related diseases but education seemed to have had great protective effect while lack of formal education served as risk factor to AD.</p>
