Dementia is becoming increasingly prevalent, and by 2026, the number of dementia patients in countries like South Korea is expected to exceed one million. This rise can be attributed to several factors, including demographic changes, improved diagnostic techniques, and the growing awareness of dementia-related conditions.
One of the primary reasons for the increase in dementia cases is the aging population. As people live longer, the risk of developing dementia naturally increases. In South Korea, for instance, the first baby boomers have reached the age of 65, significantly expanding the elderly population. This demographic shift contributes to a higher number of dementia cases, as the prevalence of dementia increases sharply with age, especially after the age of 75.
Another factor is the refinement of diagnostic criteria and the increased availability of early screening tools. These advancements allow for the detection of mild cognitive impairment at an earlier stage, which can sometimes precede dementia. In South Korea, the prevalence of mild cognitive impairment has risen significantly since 2016, partly due to these improved diagnostic methods.
Additionally, the decrease in mortality rates from cardiovascular diseases, which are linked to dementia, may also play a role. While this decrease is generally positive, it means more people are living long enough to develop dementia.
The economic and social costs of dementia are substantial. In South Korea, the cost of dementia care is estimated to be around 17.33 million won per person in community settings and 31.38 million won in facilities and hospitals. In the U.S., states like Minnesota are grappling with the financial burden of Alzheimer’s, a common form of dementia, with Medicaid spending over $1 billion annually on care.
Efforts to support families dealing with dementia are underway. In Minnesota, for example, there are proposals to establish a dedicated point person for dementia services to streamline support and reduce inefficiencies. Similarly, research into new treatments and support programs for caregivers continues, aiming to improve the quality of life for those affected by dementia
