Ageing Populations and MH Flashcards
What is demographic transition or population ageing?
The increase in life expectancy of people over 60 and
80% of those people will live in LMIC
Developing countries take less time to double over 65 population
What is the epidemiological transition framework?
As we get older the prevalence of chronic illness increases
What are the key points of Dementia?
Syndrome not disorder: Cognitive impairment.
The most common is Alzheimer’s.
Later life condition: prevalence doubles every 5 years, 5% before 50.
Low levels of awareness and help seeking
Treatment gap: 50 to 60% not diagnosed in HIC, 90% in LMIC
What is the impact of Dementia?
Dependence of individual
Increased risk for carer
Societal high cost
In LMIC it is the highest contributor of dependence and disability.
What did the EuroDEM and subsequent 10/66 studies find?
EuroDem: Lmic much lower prevalence than HIC
however lack of epidemiology cast doubt on numbers
10/66 using it’s own criteria found double the rates.
What are the estimates for dementia updated to after the WHO changed them in 2009?
47 Mil in 2015 to 135 Mil in 2050
What are the estimates for dementia updated to after the WHO changed them in 2009?
47 Mil in 2015 to 135 Mil in 2050, 58 % are in LMIC and will increase to 68% in 2050.
What is the trend of research in the field of Dementia?
Since the 80s there has been a decrease in studies in HIC and an increase in LMIC.
What is the global cost of dementia and where does it come from?
817 Mil,
87% from HIC
in LMIC the majority of that cost is Informal (60%)
Cost of care increases with dependence and co-morbidities
Where does the majority of care come from and what is it’s effect?
Informal care at home 80% of carer is female in LMIC
4 to 8 hours of care is needed.
50% with dementia have no healthcare service in 3 months.
Social changes are reducing the availability of care from informal settings.
