Current and Future Treatments in Alzheimer Disease: An Update
Open accessAbstract
Disease-modifying treatment strategies for Alzheimer disease (AD) are still under extensive research. Nowadays, only symptomatic treatments exist for this disease, all trying to counterbalance the neurotransmitter disturbance: 3 cholinesterase inhibitors and memantine. To block the progression of the disease, therapeutic agents are supposed to interfere with the pathogenic steps responsible for the clinical symptoms, classically including the deposition of extracellular amyloid β plaques and intracellular neurofibrillary tangle formation. Other underlying mechanisms are targeted by neuroprotective, anti-inflammatory, growth factor promotive, metabolic efficacious agents and stem cell therapies. Recent therapies have integrated multiple new features such as novel biomarkers, new neuropsychological outcomes, enrollment of earlier populations in the course of the disease, and innovative trial designs. In the near future different specific agents for every patient might be used in a “precision medicine” context, where aberrant biomarkers accompanied with a particular pattern of neuropsychological and neuroimaging findings could determine a specific treatment regimen within a customized therapeutic framework. In this review, we discuss potential disease-modifying therapies that are currently being studied and potential individualized therapeutic frameworks that can be proved beneficial for patients with AD.
Overview
AI snapshot
Written from the paper’s full text.
TL;DR
This narrative review summarizes current FDA-approved symptomatic treatments for Alzheimer disease and the 2019 pipeline of disease-modifying and symptomatic agents. It emphasizes that no disease-modifying therapy is approved and that future treatment may move toward biomarker-guided precision medicine.
Key findings
Current approved pharmacotherapy remains symptomatic: the 3 AChEIs donepezil, galantamine, and rivastigmine plus the NMDA antagonist memantine; no new FDA drug for AD has been approved since 2003 and there are no approved DMTs.
- A clinicaltrials.gov search accessed August 19, 2019 found 165 recruiting or active-but-not-recruiting phase 1–3 AD trials; the February 2019 pipeline review cited found 132 agents in 156 trials (28 drugs in 42 phase 3 trials, 74 drugs in 83 phase 2 trials, and 30 drugs in 31 phase 1 trials), classified as 73% DMTs, 13% symptomatic cognitive enhancers, and 11% for BPSD.
- Anti-amyloid failures include semagacestat, bapineuzumab, solanezumab, and the BACE inhibitors lanabecestat, verubecestat, and atabecestat; BACE inhibitors reduced CSF Aβ42 dose-dependently but without cognitive or functional benefit.
- Tau-directed agents remain earlier-stage: only 1 tau-related agent was in phase 2/3, 10 in phase 2, and 5 in phase 1; other DMT mechanisms include neuroprotection, anti-inflammatory effects, growth factor promotion, metabolic effects, and stem cell therapies.
Methods
Design: narrative review of current nonpharmacological and pharmacological AD management, FDA-approved medications, BPSD treatments, and phase 1–3 investigational agents.
- Data/sample: literature review plus a clinicaltrials.gov search for recruiting or active-but-not-recruiting phase 1–3 AD trials accessed August 19, 2019 (165 outcomes), and citation of the February 2019 AD drug development pipeline review (132 agents in 156 trials).
- Analysis: narrative synthesis and classification of agents by proposed mechanism—amyloid-related, tau-related, other DMT mechanisms, and symptomatic—without a formal systematic review or meta-analysis described.
Limitations
Stated: no effective treatment options and no approved DMTs exist; many trial failures are attributed to starting therapy too late, inappropriate drug doses, wrong treatment targets, inadequate understanding of AD pathophysiology, and variability in diagnostic markers and endpoints.
- Evident from the text: this is a narrative review without a stated systematic search strategy, inclusion/exclusion criteria, or risk-of-bias assessment.
- Evident from the text: pipeline findings are a cross-sectional 2019 snapshot and efficacy claims for many agents are brief, based on cited trials or conference reports rather than independent quantitative synthesis.

“A novel approach to the problem seems more technical and mathematical than biological and suggests that the selected trials’ clinical endpoint may be extremely premature, and additionally, the variability in diagnostic markers and end points may result in inaccurate diagnosis of patients’ disease state and is finally a definite source of errors.28”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
