Background: The study was conducted in the villages of Chattah zone of Purmandal health block of Jammu district, the winter capital of Jammu & Kashmir state of India on ethnic Dogra population. In earlier studies we reported on the prevalence and incidence of dementia amongst a Kashmiri migrant population now settled in Jammu district after their migration from Kashmir valley in 1990. Those studies were conducted in the migrant camp at Mishriwala, 12 km west of Jammu city. We have developed standardized study methods and instruments for use in the Dogri-speaking population, technically similar to the one previously used for screening for dementia in Mishriwala. Objective: To ascertain the prevalence of dementia in the population aged 60 years and above, and to compare prevalence of dementia in the different populations of Jammu district. Methods: A Two stage cross-sectional epidemiological study of 1,856 subjects aged 60 years and above, using cognitive and functional ability screening and clinical evaluation. Results: The overall prevalence of dementia in ethnic Dogras 60 years and over was 1.83%, with a small gender difference. Conclusion: The prevalence of dementia in ethnic Dogra population of Jammu district, North India was lower (1.83%) in comparison to the migrant Kashmiri Pandit population residing in the same district.
