A scoping review of the unique landscape and challenges associated with dementia in the Western Pacific region

Dementia is a leading public health crisis that is projected to affect 152.8 million individuals by 2050, over half of whom will be living in the Western Pacific region. To determine the challenges and opportunities for capacity building in the region, this scoping review searched databases. Our findings reveal national and ethnoracial differences in the prevalence, literacy and genetic risk factors associated with dementia syndromes, underscoring the need to identify and mitigate relevant risk factors in this region. Importantly, similar to 80% of research was derived from higher income countries, where the establishment of patient registries and biobanks reflect increased efforts and allocation of resources towards understanding the pathogenesis of dementia. We discuss the need for increased public awareness through culturally-relevant policies, the potential to support patients and caregivers through digital strategies and development of regional networks to mitigate the growing social impact and economic burden of dementia in this region.
