At the moment, dementia is affecting around 47 million people worldwide, with a forecast amount of 135 million affected people in 2050. Dementia is a growing health concern worldwide with no treatment currently available, but only symptomatic medication. Effective interventions in the prevention and management of dementia are urgently needed to contain direct and indirect costs of this disease. Indeed, the economic impact of dementia is a vast and continually growing figure, but it is still difficult to quantify. Due to an increase in both the disease spreading and its direct and indirect costs, national and international action plans have to be implemented. As a virtuous example, the Italian national plan for dementia has been summarized. Faced with an increasingly less sustainable disease impact at national and international levels, the plan suggests that it is certainly the entire welfare model that should be rethought, strengthening the network of services and providing interventions to support affected people and their caregivers. Alongside this synergistic approach, scientific research could play a crucial role for pharmacological and nonpharmacological treatments capable of delaying the state of loss of self-sufficiency of the patient, with a significant impact on social and health costs.

从全球到国家的角度预防痴呆症的社会方面：国际形势回顾和意大利实例。

目前，痴呆症正在影响全球约 4700 万人，预计到 2050 年受影响人数将达到 1.35 亿。痴呆症是全世界日益严重的健康问题，目前尚无治疗方法，只能使用对症药物。迫切需要采取有效的干预措施来预防和管理痴呆症，以控制这种疾病的直接和间接成本。事实上，痴呆症的经济影响是巨大且持续增长的数字，但仍然难以量化。由于疾病传播及其直接和间接成本的增加，必须实施国家和国际行动计划。作为一个良好的例子，意大利国家痴呆症计划已被总结。面对国家和国际层面日益难以持续的疾病影响，该计划表明，当然应该重新考虑整个福利模式，加强服务网络并提供干预措施来支持受影响的人群及其护理人员。除了这种协同方法之外，科学研究可以在药物和非药物治疗中发挥至关重要的作用，能够延缓患者失去自给自足的状态，对社会和健康成本产生重大影响。
