Introduction: A relation between literacy and dementia has been studied in past and an association has been documented. This is in spite of some studies pointing to the contrary. The current study was aimed at investigating the influence of level of literacy on dementia in a sample stratified by geography (Migrant, Urban, Rural and Tribal areas of sub-Himalayan state of Himachal Pradesh, India).
Materials and methods: The study was based on post-hoc analysis of data obtained from a study conducted on elderly population (60 years and above) from selected geographical areas (Migrant, Urban, Rural and Tribal) of Himachal Pradesh state in North-west India.
Results: Analysis of variance revealed an effect of education on cognitive scores [F = 2.823, P =0.01], however, post-hoc Tukey's HSD test did not reveal any significant pairwise comparisons.
Discussion: The possibility that education effects dementia needs further evaluation, more so in Indian context.
Keywords: Dementia; North-West India; literacy; post-hoc.
