How valuable are ecopsychosocial interventions in prevention and treatment of dementia?

Dementia is a disorder that arouses major public health interest and concern. It has been projected that there will be a global increase in the number of people affected from about 46.8million in 2018 to 131million by 2050; global cost of care for 2015 was put at US$818 billion (Prince et al., 2015). Consequently, such development will lead to tremendous social and financial cost on family and society. Currently, there is no cure for dementia and that has led to increased research activities on prevention strategies, which often has to start with a number of midlife activities. These include regular exercise, diet, treatment of cardiovascular risk factors, and social and educational stimulation through life.
