Dementia Drugs Market: Size, Share, Growth, Key Players, and Future Outlook (2025–2034)

Overview of the Dementia Drugs Market

The dementia drugs market has become a critical focus of the pharmaceutical industry due to the rising global burden of dementia, particularly Alzheimer’s disease. In 2024, the market was valued at USD 14.66 billion, primarily driven by the increasing prevalence of dementia across the 8 major markets (United States, EU5, Japan, and others).

The market is projected to grow steadily, with a CAGR of 6.20% between 2025 and 2034, reaching approximately USD 26.75 billion by 2034. This growth is fueled by ongoing drug research, advancements in neurodegenerative disease therapies, and the expansion of clinical trials focused on identifying disease-modifying treatments rather than just symptom management.

With an aging global population and the lack of curative options, the dementia drugs market is poised to play a pivotal role in transforming patient care in the coming decade.
