摘要
A feasibility study was conducted in an urban population of 3,040 in Bangalore, South India, to understand the baseline characteristics, evaluate screening questionnaires, identify potential problems and determine the magnitude of the problems. The target population was selected by a random method, from four census enumeration blocks of a specific urban area. A two-phase study design was adopted consisting of screening by trained field investigators in the initial stage and clinical examination by a neurologist in the second stage. The information was collected by an interview method on a house-to-house basis. Evaluation of the screening instruments yielded high sensitivity and specificity rates, and it became clear that there is a need to reduce false-positive results in the screening questionnaire for individuals above 7 years of age. The prevalence of neurological disorders was 32.8 per 1,000 population (with a rate of 7.8/1,000 for epilepsy). It appears feasible to detect a wide range of neurological disorders using the methods described.
