In India and abroad, projected cases of dementia are attributable to decreasing fertility and increasing life expectancy. In the paper, “Changing demography and the challenge of dementia in India”, published in Nature, researchers have said that , “In India, increasing lifespan and decreasing fertility rates have resulted in a growing number of older persons. By 2050, people over 60 years of age are predicted to constitute 19.1% of the total population. This ageing of the population is expected to be accompanied by a dramatic increase in the prevalence of dementia.”
“The Indian population currently has a very high burden of vascular risk factors, such as diabetes, hypertension and obesity, which can adversely impact the onset
and progression of dementia,” it also says and suggests that to identify risk and protective factors that contribute to dementia in India, longitudinal cohort studies like brain imaging, detailed genetic analysis and measurement of blood biomarkers need to be performed in urban and rural settings.”
