A study done using the sample of LASI (Longitudinal Aging Study in India) estimated the prevalence of Dementia among the elderly (>60 years) to be 8.44% - equating to 10.08 million people in the country.  

The subsample of LASI participants received an extensive cognitive assessment, clinical rating, and diagnoses of dementia. 

A semi-supervised machine learning model was developed to predict the status of dementia among participants without a diagnosis. 

Dementia was higher among participants who were females, lived in rural areas, and received no education. 

This study helps in making the long-term plan and social care policy.
