Alzheimer'S Disease Epidemiology

Alzheimer's disease (AD) is a prevalent neurodegenerative disorder worldwide, primarily affecting older adults. Its epidemiology reveals a rising public health concern due to aging populations globally. As of recent estimates, approximately 50 million people worldwide live with dementia, with AD contributing to 60-70% of these cases. The prevalence is projected to triple by 2050, underscoring its impact on healthcare systems and economies. AD disproportionately affects women and those with a family history of the disease. Key risk factors include age, genetic predisposition (e.g., ApoE4 allele), and lifestyle factors such as cardiovascular health. Addressing AD's epidemiology necessitates enhanced awareness, early detection strategies, and ongoing research into effective treatments and preventive measures to mitigate its growing burden on societies worldwide.
