Reimbursement Policy

Reimbursement policies for Alzheimer’s drugs remain highly restrictive and vary across regions, reflecting the high costs and limited efficacy of available treatments. In the United States, Medicare—the primary payer for elderly patients has taken a cautious approach. For example, it initially limited coverage for Aduhelm to clinical trial participants due to uncertainties about clinical benefit versus cost. Similarly, coverage for Leqembi was expanded in 2023 but only under a “coverage with evidence development” model, requiring patients to be part of a registry to monitor real-world effectiveness. Japan has approved Leqembi for national health insurance reimbursement, but with strict monitoring and budget controls. A growing trend across countries is the adoption of conditional reimbursement frameworks, such as risk-sharing agreements or registry-linked coverage, where funding is tied to actual treatment outcomes. These measures aim to contain public spending while ensuring that only clinically effective drugs receive broad reimbursement.

Alzheimer’s Drugs Market Insights, By Drug Class

Cholinesterase Inhibitors Segment Leads the Market Due to Its Ability to Meet Unmet Needs

In terms of drug class, cholinesterase inhibitors segment is estimated to contribute the highest Alzheimer’s drugs market share of 40.5% in 2025, owing to its ability to meet significant unmet needs. Cholinesterase inhibitors work by increasing levels of a chemical messenger in the brain called acetylcholine, which can help slow decline in thinking skills, memory and other functions. These are some of the first treatments approved specifically for Alzheimer's disease and remain a core therapeutic option for many patients. The mechanism of action targeting acetylcholine neurotransmission addresses a key pathological process in Alzheimer's and provides symptomatic benefit. Cholinesterase inhibitors offer oral administration convenience as compared to other treatment approaches in development. The efficacy demonstrated on cognitive and functional outcomes has led to their widespread adoption as the frontline pharmacotherapy for mild-to-moderate Alzheimer’s disease.

In August 2024, A Swedish registry study led by Karolinska Institute, published in Alzheimer’s & Dementia, evaluated 1,095 dementia with Lewy bodies (DLB) patients over a decade. Findings show that cholinesterase inhibitors (ChEIs), such as rivastigmine, donepezil and galantamine, significantly slowed cognitive decline, dropping MMSE (Mini-Mental State Examination) scores by just ‑0.39 points yearly versus ‑2.49 (memantine) and ‑2.50 (no treatment). Additionally, ChEI users faced a 34% lower risk of death in the first-year post-diagnosis (adjusted HR 0.66). 

Alzheimer’s Drugs Market Insights, By Route of Administration

Oral Segment Dominates by Maximizing Patient Adherence

In terms of route of administration, oral segment is estimated to contribute the highest market share of 58.5% in 2025, owing to its advantage of maximizing patient adherence to treatments. For most Alzheimer's patients in the mild-to-moderate stages of the disease, oral administration of medicines is preferred as it is non-invasive and can be self-administered at home without need for clinic visits. The convenience of oral dosing encourages compliance with the treatment regimen over an extended period of time that may span years. This is critically important for Alzheimer's where continuous management is required as symptoms progress. Administering medicines orally also avoids introduction of potential infection risks as compared to parenteral routes and additional cost burdens to healthcare systems as compared to injection administration. Positive effects on cognition and function rely upon consistent intake of therapies as prescribed over the long term.

In May 2023, the FDA granted supplemental approval for Rexulti (brexpiprazole) oral tablets, the first drug certified to treat agitation in dementia due to Alzheimer’s disease. Two 12‑week Phase 3 trials demonstrated significant reductions in caregiver‑reported agitation at 2–3 mg doses. Starting at 0.5 mg, doses can escalate to 3 mg based on patient response.

Alzheimer’s Drugs Market Insights, By Distribution Channel

Hospital Pharmacies Segment Drives Due to Reinforcing Care Models

In terms of distribution channel, hospital pharmacies segment is estimated to contribute the highest market share of 45.5% in 2025, owing to its role in reinforcing integrated care models for Alzheimer’s patients. Alzheimer's treatment necessitates a multidisciplinary approach beyond just pharmacotherapy alone. Hospital pharmacies play a central part in coordinating the delivery of comprehensive Alzheimer's care. These work closely with memory clinics, geriatric specialists, nursing staff and social workers to ensure medications are prescribed appropriately and patients transition smoothly between inpatient and outpatient settings as their needs change. Many hospitals also run specialized dementia day programs, providing therapy and respite to delay nursing home placements. The hospital pharmacies act as an anchor, supporting a holistic care model where medication optimization occurs in the context of multifactorial assessment and non-drug interventions.

In December 2024, IDIBAPS–Hospital Clínic Barcelona took part in the HUB Alzheimer Barcelona initiative.

Market Report Scope

Alzheimer’s Drugs Market Driver

Aging Population and Prevalence of Alzheimer's

Due to rising life expectancy, there has been increase in number of elderly people aged 65 years and over. According to WHO, the proportion of the world's population over 60 years will nearly double from 12% to 22% between 2015 and 2050. Elderly population is particularly susceptible to neurodegenerative conditions such as Alzheimer's and dementia due to natural age-related cognitive decline. Alzheimer's disease is the most common cause of dementia among older adults. As more people survive into their 80s and beyond, even a small increase in diagnosis rates in the very old can cause a dramatic rise in prevalence numbers. In 2023, According to Alzheimer’s Disease International report, around 55 million people have dementia worldwide, the number of people affected is set to rise to 139 million by 2050, with the greatest increases in low- and middle-income countries. Growing elderly populations can increase Alzheimer's cases without effective prevention or cure strategies.

Novel Drug Targets and Pipeline Progress

After multiple past failures in treatment development for Alzheimer's, the currently approved medicines can only manage symptoms temporarily without altering disease progression. There has been promising pipeline activity that explores novel mechanisms and molecular targets beyond the amyloid hypothesis. Several companies are developing disease-modifying drugs targeting tau tangles, neuroinflammation, synaptic dysfunction, and other pathways increasingly implicated in Alzheimer's pathology. Large late-stage trials are ongoing to evaluate anti-amyloid antibodies as well as anti-tau antibodies and small molecules for preventing or slowing cognitive decline. Some potential first-in-class therapies for early Alzheimer's include anti-Tau antibody crenezumab from Genentech and anti-amyloid gamma secretase modulator verubecestat from Merck.

Alzheimer’s Drugs Market Opportunity

Growth in Geriatric Population

The global rise in the elderly population presents a significant opportunity for Alzheimer’s drugs market forecast, driven by increased demand for effective treatments among aging demographics. Alzheimer’s typically affects individuals 65 years and older, and as global life expectancy climbs, so does the number of potential patients. For instance, a recent tool developed by Duke, Harvard, and the University of Otago called DunedinPACNI uses MRI data to predict dementia risk, highlighting the urgency for early intervention before irreversible damage occurs. Moreover, new therapies are emerging: in late 2023, the FDA granted accelerated approval to donanemab (Kisunla) and approved Zunveyl, a prodrug version of galantamine with fewer gastrointestinal side effects, offering patients more tolerable options. These advances underscore a shifting focus toward interventions that delay the onset or progression of Alzheimer’s. As a result, pharmaceutical companies and healthcare providers are well-positioned to serve an expanding cohort of older adults seeking cognitive-preserving treatments, positioning the Alzheimer's drugs market for sustained growth.

Analyst Opinion (Expert Opinion)

• The Alzheimer’s drugs market is at an inflection point, shaped less by the incremental approval of symptomatic treatments and more by a deepening recognition of the biology of neurodegeneration. Despite decades of clinical stagnation, recent regulatory shifts and clinical trial outcomes are redefining the treatment landscape, albeit with challenges that remain underappreciated in public discourse.
• The U.S. FDA’s approval of lecanemab (Leqembi) in 2023 under the Accelerated Approval pathway, followed by its full traditional approval, is emblematic of a shift toward disease-modifying therapies (DMTs) targeting amyloid-beta.
• Moreover, the market’s trajectory is constrained by the biological complexity of Alzheimer’s. Tau-targeting drugs, once considered the logical successors to anti-amyloid therapies, have yet to demonstrate convincing clinical efficacy in Phase III trials. For instance, semorinemab failed to show significant benefit in slowing disease progression in Genentech's LAURIET study. This has raised doubts about the translatability of biomarker changes into meaningful cognitive outcomes.
• In our view, the market remains fragmented between high-investment, low-return DMT candidates and legacy cholinesterase inhibitors and NMDA receptor antagonists, which still dominate prescriptions globally due to affordability and familiarity. Donepezil, rivastigmine, and memantine continue to account for over 60% of all Alzheimer’s prescriptions globally, particularly in Asia and Latin America, where regulatory approvals of newer agents are slow and healthcare systems are cost-sensitive.
• Crucially, innovation is shifting toward combination approaches and precision targeting. Companies such as Acumen Pharmaceuticals and Cassava Sciences are exploring early-stage interventions and novel mechanisms beyond amyloid and tau, such as soluble Aβ oligomers and neuroinflammation. The success or failure of these platforms will determine whether the market continues its high-risk, capital-intensive trajectory or recalibrates toward more sustainable development models.
• In conclusion, while recent regulatory approvals have injected optimism, the Alzheimer’s drugs market is driven by regulatory accommodation and biotech speculation. Without clinically meaningful outcomes, payer support, and patient-centric models, the long-term viability of this market, especially for high-cost biologics remains uncertain. As the industry shifts from biomarker-driven optimism to functional efficacy, true innovation will depend on broader biological targets, better trial designs, and a willingness to move beyond the decades-old paradigms that have thus far yielded underwhelming therapeutic results.
