Are you asserting dementia and neurodegeneration don't exist in India, or merely not in your set of close personal acquantances? Because if its the latter, that... hardly means anything. The expected prevalence even with a past history of diseases that increase the risk isn’t high enough that it not happening that you are aware of in your personal circle is... really noteworthy at all, unless your circle is large and/or you have detailed access to the private medical information of everyone in it.
