Interest in the role of social networks as a protective factor in the development of dementia over the last decade has increased with a number of longitudinal studies being published on the possible association of different lifestyles with dementia. This review examines and provides a summary of the published longitudinal studies exploring the effect of social network on dementia, with particular focus on their relevance to the Indian society. Potential cognitive and biological mechanisms mediating the effects of social networks on dementia are discussed. Results from observational studies suggest that degree of social engagement, marriage, living with someone and avoiding loneliness may have a protective effect on developing dementia that could be applicable to both Indian and western societies. A deeper analysis of the nature of social networks and dementia pertinent to Indian society is awaited.
