To describe the methods and general results of the baseline longitudinal survey in a defined cohort of elderly people from three areas of Central Spain (urban and rural). The survey was designed to study dementia, essential tremor, Parkinson's disease and stroke.
A population-based longitudinal study with door-to-door interviews.
This study was carried out in two phases: Phase 1 (health status questionnaire and screening performed by lay interviewers) and Phase 2 (diagnosis of neurological illnesses by neurologists).
The study flow chart, screening instruments for neurological disorders, main demographic data (age, sex, educational attainment, occupation) and general health status of the 5,278 screened participants (2,238 men and 3,040 women) are given for the two phases. The response rate was 85.3%, and participation was higher in men and in the urban area.
Participation rates were good in both phases of the NEDICES baseline study, and this was influenced by age, sex and setting of the participants. Educational attainment, occupation and health status data are analogous to other Spanish studies performed in the elderly. As the study population was large and good participation rates were achieved, precise analysis of morbidity of the neurological disorders investigated will be possible.
描述对来自西班牙中部三个地区（城市和农村）特定老年人群队列进行基线纵向调查的方法和总体结果。该调查旨在研究痴呆、特发性震颤、帕金森病和中风。
一项基于人群的纵向研究，采用挨家挨户访谈的方式。
本研究分两个阶段进行：第一阶段（由非专业访谈员进行健康状况问卷调查和筛查）和第二阶段（由神经科医生诊断神经疾病）。
给出了两个阶段5278名接受筛查参与者（2238名男性和3040名女性）的研究流程图、神经疾病筛查工具、主要人口统计学数据（年龄、性别、教育程度、职业）和总体健康状况。应答率为85.3%，男性和城市地区的参与率更高。
NEDICES基线研究的两个阶段参与率都很高，这受到参与者年龄、性别和地点的影响。教育程度、职业和健康状况数据与西班牙其他针对老年人的研究类似。由于研究人群规模大且参与率高，因此有可能对所研究的神经疾病发病率进行精确分析
