Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that primarily affects the elderly, leading to severe cognitive decline and memory loss. The global prevalence of Alzheimer’s is rising rapidly due to increasing life expectancy and an aging population. As of 2023, it is estimated that over 50 million people worldwide are living with Alzheimer’s disease. The socioeconomic burden of Alzheimer’s disease is immense, encompassing direct medical costs, indirect costs, and the emotional toll on patients and their families. Direct medical costs include expenses for diagnosis, treatment, and long-term care. These costs are substantial because Alzheimer’s patients often require continuous care, including home care services, assisted living, and nursing home care. The indirect costs primarily involve lost productivity, both from patients who can no longer work and from caregivers who may reduce their working hours or leave their jobs to provide care. The emotional and psychological burden on caregivers is also significant. Family members and friends who provide care often experience high levels of stress, depression, and physical health issues. The time-intensive nature of caregiving can strain personal relationships and reduce the quality of life for both caregivers and patients. Efforts to address the socioeconomic impact of Alzheimer’s disease involve a multifaceted approach, including advancing research for early diagnosis and treatment, improving care facilities, and providing support systems for caregivers. Public health strategies also emphasize the importance of lifestyle changes and preventive measures that may reduce the risk of developing Alzheimer’s. The section provides a comprehensive overview of Alzheimer’s Disease, beginning with its epidemiology, and examining the social and economic challenges.. The section examines demographic shifts, such as aging populations, that increase Alzheimer’s prevalence and considers the implications for public policy and resource allocation for care. This part of the book also examines the social and economic challenges posed by Alzheimer’s Disease, and the direct and indirect costs associated with the disease, including medical care, lost productivity, and the emotional and financial impact on caregivers.
