Globally, 24.3 million people are affected by dementia and 4.6 million new cases occur annually. The prevalence of dementia is expected to double every 20 years, reaching 81.1 million by 2040. The authors report that two-thirds of people with dementia live in LMICs, where there are few services available and levels of awareness concerning the condition, and help-seeking to treat it, are low.
The authors suggest that the principal goals for management of dementia are detecting and treating behavioral and psychological symptoms early; optimizing cognition, activity, and wellbeing; and providing information and long-term support to carers. They argue that routine packages of continuing care should be employed, comprising of diagnosis coupled with regular needs assessments, physical health checks, and carer support.
