Revealing a hidden problem. An evaluation of a community dementia case-finding program from the Indian 10/66 dementia research network.
BACKGROUND
Dementia in India is largely a hidden problem with no community awareness and little help seeking from affected families, despite high levels of strain. Cases must therefore be identified before practical help can be offered.


METHODS
After two and a half hours of formal training, local community health workers in rural Kerala were asked to identify possible cases of dementia from the community they served. Diagnoses were then verified by a senior local psychiatrist with clinical and research interests in old age psychiatry.


RESULTS
The community health workers identified 51 out of 1979 over 60 year old residents (a prevalence of 2.6%) as suspected cases of dementia. Following the psychiatrist's assessment, 33 met DSM-IV criteria for dementia. The majority of confirmed cases were of the Alzheimer's Disease sub-type. Most "non-cases" were found to be suffering from other major psychiatric disorders, with substantial unmet need. The positive predictive value of the community health workers informal screening was 64.7%.


CONCLUSIONS
This simple cost-effective case-finding method can be of practical use in the development of community based dementia care services in India and other developing countries with similar health care systems.
