The world's population is ageing hence the
world is graying. The elderly population is
substantially increasing not only in the high
income countries but also in the low and
middle income countries (LMICs) like Nepal
in the past decade. As the world is graying,
the chronic medical and neurological disease
like dementia is expected to increase with
elderly population growth. According to the
WHO report 1
between 2% and 10% of all
cases of dementia start before the age of 65.
The prevalence doubles with every five-year
increment in age after 65. In other words, the
prevalence of dementia is 5% for aged 65-70,
10% for 75-80, and even more after age 80.
