As per the Global Burden of Disease (GBD) study (India State-Level Disease Burden Initiative Neurological Disorders Collaborators, 2021), 3.69 million people were living with Alzheimer’s disease and other dementias in 2019 in India. The GBD study (India State-Level Disease Burden Initiative Neurological Disorders Collaborators, 2021) also provides state-wise prevalence and crude DALY rate for Alzheimer’s disease and other dementias per 100,000 in 2019 (Table 6.3).

Table 6.3 depicts state wise prevalence and crude DALY rate (2019) – per 100,000

The numbers of persons with dementia are further estimated to increase by 197% between 2019-2050 in India, with 11.4 million people projected to live with dementia in India in 2050 (GBD 2019 Dementia Forecasting Collaborators, 2022).
