January 7, 2025 – The global prevalence of Alzheimer’s disease (AD) is expected to increase significantly over the next decade, with cases in eight major markets set to rise from 15.99 million in 2023 to 22.51 million in 2033. This marks an annual growth rate (AGR) of 4.08%, according to a report released by GlobalData, a leading data and analytics company.
China is predicted to have the highest number of AD cases in 2033, with an estimated 10.4 million prevalent cases, while Spain is expected to report the lowest number at 0.62 million cases, the report noted.
In 2023, women were disproportionately affected by the disease, making up approximately 73% of the total prevalent cases. Older adults aged 75 and above represented nearly 79% of all AD cases in the eight major markets, with individuals aged 65-74 accounting for the remaining 21%.
The severity of Alzheimer’s varies, with the report estimating that in 2023, about 55% of prevalent cases were classified as mild, while only 16% were severe.
Antara Bhattacharya, associate project manager for the epidemiology team at GlobalData, highlighted the pressing concern of mortality in individuals living with Alzheimer’s. “Mortality remains a significant concern for individuals living with AD and their families,” said Bhattacharya. “Efforts to prevent or delay the disease are expected to have a profound impact on long-term outcomes, as the value of treatment will largely depend on a therapy’s effectiveness in reducing morbidity and extending life expectancy.”
The report emphasized the need for multifaceted approaches to AD treatment, which combine medical interventions, lifestyle modifications, continuous support, clinical trials, and follow-up care.
In addition, the report underscored the importance of research to better understand the relationship between Alzheimer’s disease and mortality, urging further studies that could lead to more effective treatments and management strategies.
As Alzheimer’s disease continues to affect a growing number of individuals worldwide, experts stress the importance of early detection, intervention, and comprehensive care plans to improve the quality of life for those impacted by the disease.
