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 crosssectional 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.

Objective: The aim of the study was to assess the prevalence of stroke in a migrant community (Kashmiri) settled in Jammu district of J&K, India. Methods: The study was conducted as a population based cross-sectional study at Mishriwala, 12 kms west of Jammu city. A door to door survey of 964 individuals of Mishriwala community cluster was conducted with a participation rate of 95%. Results: Eight cases of completed stroke were ascertained yielding a crude prevalence rate of 1,169/100,000 (95% CI=300/100,000-1,700/100,000) in the age group 15 years and above. When the prevalence was standardized to world standard population for age, the prevalence was slightly lower at 856/100,000 (95% CI=400/100,000-11,000/100,000). The proportion of stroke occurring in females (63%) was higher than that in males and the age-specifi c prevalence increased with age. Conclusion: The prevalence rate of stroke among Kashmiri Pandits is comparable to rates reported from the developed world.
