According to the WHO data published in March 2023, more than 55 million people suffer from dementia worldwide and it is predicted to reach 78 million and 139 million by 2030 and 2050, respectively. Moreover, around 10 million new cases of the disease are reported every year. The prevalence of the disease is comparatively higher in developing economies, such as China, India, and Brazil. The introduction and development of novel therapeutic products for different types of dementia is expected to support the growth. In November 2023, Eisai Co., Ltd. announced the launch of Leqembi in the U.S. market and the company aimed that the drug would be prescribed to 10,000 patients by the end of March 2024. Leqembi received approval from the U.S. FDA in July 2023.

Favorable initiatives are being undertaken by government and non-government bodies to improve the overall healthcare services for patients and spread awareness among people. In December 2023, the U.S. Department of Health & Human Services (HHS) released a roadmap of strategies to support research activities, increase treatment rates, improve health services to support dementia patients, and encourage action to reduce risk factors associated with the disease. Similarly, in September 2022, Corium, Inc. announced the availability of Adlarity (donepezil transdermal system) for prescription in the U.S. for the treatment of mild, moderate, or severe dementia related to Alzheimer’s disease. In March 2022, the U.S. FDA approved Adlarity for the treatment of Alzheimer’s disease dementia.

Moreover, government bodies are providing financial aid to accelerate clinical research to develop novel drugs for the targeted disease. For instance, in November 2023, the National Institutes of Health announced a funding opportunity for the development of novel therapeutic drugs for Alzheimer’s disease and related dementia. The funding will be provided to support phase 1 and 2 clinical trials to accelerate the evaluation of promising drug candidates. The presence of strong pipeline candidates under clinical trials for dementia is expected to boost market expansion. As of January 2023, there were 36 drugs in phase-3, 87 drugs in phase-2, and 31 drugs in phase-1 clinical trials.

Increasing R&D activities to develop novel biological and other drug classes are anticipated to fuel market growth. Clinical studies related to anti-amyloid antibodies show promising results in clinical trials. For instance, lecanemab and donanemab drug candidates showed cognitive decline by 27% at 18 months of treatment and about 35% at 18 months of treatment, respectively. Moreover, amyloid clearance was observed in 68% of participants in the phase-3 trial of lecanemab and 80% in the donanemab phase-3 trial.

Market Dynamics

The Dementia Treatment Market is experiencing steady growth driven by the rising prevalence of dementia disorders and the increasing aging population worldwide. Growing awareness of early diagnosis and disease management is supporting demand for pharmacological therapies and supportive care solutions. Healthcare systems are focusing on improving access to treatment options as the economic and social burden of dementia continues to increase. For instance, in 2025, healthcare providers and pharmaceutical companies expanded efforts to integrate newly approved disease modifying therapies for Alzheimer’s disease into clinical practice, reflecting a shift toward treatments that target underlying disease mechanisms rather than symptom management alone. Ongoing investments in neurological research, biomarker-based diagnostics, and personalized treatment approaches are further strengthening market development. At the same time, challenges related to high treatment costs, limited curative options, and reimbursement complexities continue to influence adoption rates. Increasing collaboration between healthcare organizations, research institutions, and drug manufacturers is expected to support innovation and improve long term treatment outcomes across the dementia care landscape.
