Alzheimer's disease (AD, the most common form of dementia) accounts for 60% prevalence in LDCs (Kalaria et. al., 2008). A survey led by experts commissioned by Alzheimer's Disease International estimated that 24.3 million people suffered from dementia in 2005, and 4.6 million new cases were reported annually (Kalaria et. al., 2008). Projections by Alzheimer's Disease International and WHO propose that by 2050, 115 million people will be living with AD/ dementia globally, of which a growing proportion will reside in LDCs (approximately 55 million by 2020 according to WHO) (Kaneda, 2006). There is a common awareness about its final stages which comprise of: loss of reasoning, memory, speech, along with other cognitive functions. In most LDCs, …show more content…

This results in a bigger elderly population that is more susceptible to noncommunicable diseases than the younger population. This increase in the prevalence of noncommunicable and degenerative diseases is the new trend that is occurring globally regardless of income level (Figure5); and is also attributed to the waning of mortality rates that are a result of socioeconomic growth. Affirmation from the Global Burden of Disease project, as well as other international epidemiologic research, shows that in 10 to 20 years, people from various global regions will suffer from NCDs like heart disease, diabetes and cancer, than from communicable diseases …show more content…

The inhabitants of most developing regions still from a tremendous disease burden incurred by diarrhoea, tuberculosis (TB), HIV/AIDS, pneumonia, malaria and other pathogens (Figure6). The ≥60 years population in these regions are no exception to this burden. According to WHO Report of 2002, diarrhoea is the third leading cause of death among the ≥60 population in LDCs (Gavazzi, Herrmann & Krause, 2004). Influenza-like illness and pneumonia continually consume the lives of the elderly populations in Taiwan, South Africa, Brazil, China and Argentina. In countries like Senegal and India, meningitis is the fourth-most common pathology requiring hospitalisation, with infected elder populations at higher risks of longer hospitals stays and secondary disability (Gavazzi et. al., 2004; Dye,
