Global Diseases Deserve Global Solutions: Alzheimer's Disease

Alzheimer's Disease (AD) is a global issue, with increasing incidence and prevalence as the world's population ages and life expectancy increases. Projections indicate that by 2050, over 150 million individuals worldwide will be personally living with AD, an impending crisis made worse by the absence of cure therapies. Moreover, the risk factor relationship of dementia with rising global temperatures and air pollution further necessitates the urgency of a coordinated international response. With an extensive economic and emotional burden, AD is no longer just a disease; it is a worldwide societal crisis. This review presents five calls to action to address the AD global health emergency. First, AD research must be approached as an internationally performed activity, involving standardized data sharing, collaborative innovation, and improved access to pharmaceutical studies in low- and middle-income countries (LMICs), alongside increased diversity, inclusion, and equity in research. Second, there must be a commitment to develop universally accessible, affordable, and non-invasive diagnostic tools for AD. Third, advancements in AD therapeutics should prioritize the development of affordable agents, allowing for widespread geographic distribution. Fourth, we identify focus areas for global dementia risk reduction: sleep, head injury prevention, exercise, learning, and diet (SHIELD risk reduction strategy). Fifth, improving care for individuals with AD requires eliminating stigma through educational programs for both the public and caregivers. The escalating AD crisis demands an unprecedented global coalition in research, diagnostics, therapeutics, prevention, and education to avoid a future where the disease becomes the defining crisis of our era.
