OBJECTIVE: Few studies regarding the epidemiology of essential @entity400 (ET) and its @entity1109 ( @entity1109 ) have been conducted to date. We thus conducted a door-to-door survey to investigate the ET and its @entity1109 and their clinical manifestations in a rural area of Shanghai, China. METHODS: We recruited 19,614 residents (>= 50 years old), living in Malu town, Shanghai. Investigations were divided into two steps. In first step, trained physicians conducted door-to-door surveys and reported probable ET subjects to @entity717 specialists. In the second step, @entity1 with suspected ET had their diagnosis confirmed by @entity717 specialists. We randomly selected 123 subjects from those adults who screened negative for neurological conditions as healthy controls for the study of @entity1109 . RESULTS: The prevalence of ET in individuals (>= 50 years old) was 0.306% (PR  =  3.06 per 1000). The mini-mental state examination (MMSE) scores were lower in ET @entity1 than in controls (25.81      4.20 vs. 26.63      3.14,  P=  0.024). Complaints of @entity4531 reported by ET @entity1 were significantly higher than those in controls (P  <  0.05). In contrast, we did not observe a significant difference for other @entity1109 between ET @entity1 and controls, including olfactory function (P  =  0.82), @entity308 (P  =  0.94), and @entity735 movement @entity146 (RBD) (P  =  0.71). CONCLUSIONS: The prevalence of ET in @entity1 >= 50 years old in a rural area of Shanghai China is low. Prevalence of certain NMSs was higher among @entity1 with ET relative to health controls.
