Global Alzheimer’s Disease Therapeutics Market - 2025-2033

The global alzheimer’s disease therapeutics market size reached US$ 24.27 billion in 2024 and is expected to reach US$ 46.47 billion by 2033, growing at a CAGR of 7.5% during the forecast period 2025-2033.

Alzheimer’s disease is a progressive neurodegenerative disorder that primarily affects older adults, leading to a decline in memory, thinking abilities, and overall cognitive function. It is the most common cause of dementia. The disease is characterized by the accumulation of beta-amyloid plaques and neurofibrillary tangles in the brain, which disrupt communication between neurons and eventually cause cell death. As the disease progresses, individuals lose the ability to perform daily activities, and in advanced stages, may become completely dependent on caregivers.

Alzheimer’s disease therapeutics encompass a range of treatments aimed at managing symptoms, slowing disease progression, and improving patients' quality of life. Current pharmacological therapies are primarily categorized into symptomatic treatments and disease-modifying approaches. Symptomatic treatments, such as cholinesterase inhibitors and the NMDA receptor antagonist memantine, help maintain cognitive function by enhancing neurotransmitter activity, particularly in the early to moderate stages of the disease.

Market Dynamics: Drivers & Restraints

Rising Prevalence of Alzheimer's Disease

The growing prevalence of Alzheimer’s disease is poised to be a major driver of the healthcare market in the coming years. With aging populations, the number of Alzheimer’s cases is rising rapidly, creating an urgent demand for improved diagnostic tools, effective treatments, and comprehensive care solutions. Alzheimer’s affects approximately 50-60% of people suffering from dementia.

For instance, according to CSIR-NIScPR, Alzheimer's disease presents a significant global health burden in 2023, with the latest estimates indicating that more than 57.4 million people are currently affected by the condition. The Global Burden of Disease Study (GBDS) 2019 predicts that between 2019 and 2050, the number of dementia cases will increase by a staggering 166%, impacting approximately 152.8 million individuals. These projections align closely with those made by the World Health Organization (WHO), highlighting the growing prevalence of the disease and its substantial impact on global healthcare systems.

According to the Alzheimer’s Disease International Organization estimated that, the number of individuals with dementia will reach about 78 million in 2030 and 139 million in 2050. With the increasing dementia, the individuals with alzheimer’s is expected to grow, increasing the demand for alzheimer’s therapeutics and further driving the market growth.

This trend is prompting increased investment from pharmaceutical companies, healthcare providers, and biotech firms focused on developing innovative therapies and early detection methods. At the same time, governments and private organizations are boosting funding for public awareness, caregiver support, and long-term care infrastructure.

As a result, the Alzheimer’s care ecosystem is expanding, presenting both a pressing public health challenge and a significant opportunity for growth across multiple sectors of the healthcare industry.

Regulatory and Approval Challenges

Regulatory and approval challenges pose a significant barrier to the growth of the Alzheimer’s disease therapeutics market. Developing drugs for Alzheimer’s is particularly complex due to the disease’s slow and variable progression, which makes it difficult to demonstrate clear clinical benefits in trials. Regulatory bodies such as the FDA and EMA require extensive data to prove not only safety but also long-term efficacy, often through large, multi-year Phase III studies. These requirements significantly extend development timelines and increase costs, while offering no guarantee of approval.

Segment Analysis

The global alzheimer’s disease therapeutics market is segmented based on stage, drug class, and region.

Drug Class:

The cholinesterase inhibitors segment is expected to dominate the alzheimer’s disease therapeutics market with the highest market share

The cholinesterase inhibitors segment is expected to remain dominant in the alzheimer’s disease therapeutics market due to their established efficacy, affordability, and broad clinical application. Drugs like donepezil, rivastigmine, and galantamine work by inhibiting the breakdown of acetylcholine, a neurotransmitter crucial for memory and cognitive function. This mechanism helps alleviate symptoms, particularly in patients with mild to moderate Alzheimer’s, offering modest improvements in cognitive abilities.

The rising global prevalence of Alzheimer’s disease, which is expected to affect over 150 million people by 2050, further strengthens the demand for these therapies.

Additionally, ongoing clinical trials aim to assess its efficacy and safety across various patient populations, ensuring continued innovation within this drug class. The approval of new formulations that reduce gastrointestinal side effects also enhances the market's appeal. As the global prevalence of Alzheimer’s increases, the continued research, effectiveness, and cost-effectiveness of cholinesterase inhibitors will solidify their dominant position in the market.

Geographical Analysis

North America is expected to hold a significant position in the global alzheimer’s disease therapeutics market

North America is expected to maintain a dominant position in the global Alzheimer’s disease therapeutics market, driven by several key factors. The growth is supported by a high prevalence of Alzheimer’s, significant investments in research and development. For instance, according to the Alzheimer's Association, an estimated 7.2 million Americans aged 65 and older are living with Alzheimer's disease in 2025, with 74% of them being 75 years or older. By 2050, this number is expected to nearly double, reaching close to 13 million. Approximately 1 in 9 individuals aged 65 and older will be affected by Alzheimer's. Furthermore, the health and long-term care costs for people living with dementia are projected to reach $384 billion in 2025 and nearly $1 trillion by 2050.

The presence of major pharmaceutical companies, favorable reimbursement policies, and strong government support for Alzheimer’s research further bolsters the region's market growth. North America continues to lead in Alzheimer's treatment developments. For instance, in July 2024, Eli Lilly and Company announced that the U.S. Food and Drug Administration had approved Kisunla (donanemab-azbt). This once-monthly injection for early symptomatic Alzheimer's, including mild cognitive impairment (MCI) and mild dementia with confirmed amyloid pathology, is the first amyloid plaque-targeting therapy with evidence supporting stopping treatment after plaque removal.

This breakthrough therapy not only offers potential clinical benefits but also promises lower treatment costs and fewer infusions, further solidifying North America's dominant position in the Alzheimer's therapeutics market. Additionally, advancements in treatment options contribute to North America's market leadership.
