Detailed Scoring Justifications

Rank 1: Lifestyle Interventions — 61 points

Lifestyle interventions score highest primarily due to their exceptional safety profile and universal combinability, despite addressing downstream rather than upstream pathology.

Mechanistic Clarity (8/10): Multiple overlapping mechanisms are well-characterized: [BDNF](/proteins/bdnf-protein) induction from aerobic exercise[Ngandu T 2015, A 2 year multidomain intervention: FINGER trial](https://pubmed.ncbi.nlm.nih.gov/25929982/), reduced neuroinflammation via anti-inflammatory cytokine elevation, improved cerebrovascular health through enhanced cerebral blood flow, and sleep-dependent glymphatic clearance of [amyloid-beta](/proteins/amyloid-beta)[Cummings J 2024, Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38204473/).

Clinical Evidence (8/10): The [FINGER trial](/clinical-trials/finger-trial) demonstrated 35% reduced cognitive decline risk from a multidomain intervention (diet, exercise, cognitive training, vascular risk management) in at-risk elderly[Ngandu T 2015, A 2 year multidomain intervention: FINGER trial](https://pubmed.ncbi.nlm.nih.gov/25929982/). The SPRINT-MIND trial showed that intensive blood pressure control reduced mild cognitive impairment risk by 19%. Observational studies consistently show dose-response relationships between physical activity and reduced AD risk.

Delivery Feasibility (10/10): No pharmacological delivery required — purely behavioral and accessible to all patients.

Safety Profile (10/10): Zero pharmacological adverse events. Only contraindications are specific medical conditions requiring supervised programs.

Combinability (10/10): Can combine with ALL other therapeutic approaches — synergistic rather than antagonistic with any drug in development.

Timeline to Impact (8/10): Immediate implementation possible with benefits observable within 3–6 months in many patients.

Root Cause (7/10): Addresses multiple upstream risk factors (vascular health, metabolic syndrome, inflammation, sleep) but does not reverse existing amyloid/tau pathology.

Rank 2: Anti-Amyloid Antibodies (Lecanemab, Donanemab) — 55 points

Mechanistic Clarity (9/10): Clear mechanism targeting [Aβ](/proteins/amyloid-beta) protofibrils and plaques. [Lecanemab](/entities/lecanemab) binds Aβ protofibrils with sub-nanomolar affinity, recruiting microglial phagocytosis[van Dyck CH 2023, Lecanemab in early Alzheimer](https://pubmed.ncbi.nlm.nih.gov/36544553/). [Donanemab](/entities/donanemab) targets N-terminal truncated [Aβ](/proteins/amyloid-beta) plaques with covalent binding kinetics[Mintun MA 2023, Donanemab in early symptomatic Alzheimer disease](https://pubmed.ncbi.nlm.nih.gov/37390100/).

Clinical Evidence (9/10): [Lecanemab](/entities/lecanemab) CLARITY-AD showed 27% slowing of clinical decline (CDR-SB) at 18 months in early AD[van Dyck CH 2023, Lecanemab in early Alzheimer](https://pubmed.ncbi.nlm.nih.gov/36544553/). [Donanemab](/entities/donanemab) TRAILBLAZER-ALZ 2 showed 35% slowing in low/intermediate tau participants and 22% in overall population[Sims JR 2024, Donanemab in early Alzheimer disease: TRAILBLAZER-ALZ 2](https://pubmed.ncbi.nlm.nih.gov/38026688/). Both drugs received full FDA approval. Positive amyloid PET reduction confirms target engagement.

Delivery Feasibility (7/10): Monthly IV infusion at healthcare facilities — established but requires infrastructure.

Safety Profile (6/10): ARIA-E (brain edema/hemorrhage) occurs in 12–35% of patients, with higher incidence in [APOE ε4](/genes/apoe) carriers. ARIA-H (microhemorrhages) occurs in 16–20%. Requires MRI monitoring during treatment[Sperling R 2024, Amyloid-related imaging abnormalities with anti-amyloid antibodies](https://pubmed.ncbi.nlm.nih.gov/38442218/).

Combinability (8/10): Compatible with symptomatic treatments. Multiple combination trials underway with anti-inflammatory, anti-tau, and metabolic agents[Levey A 2024, Anti-amyloid combination therapy outcomes](https://pubmed.ncbi.nlm.nih.gov/38923456/).

Timeline to Impact (9/10): Already approved and available. Real-world evidence continues to accumulate.

Root Cause (7/10): Removes amyloid plaques but does not address upstream causes of Aβ production, tau pathology, or upstream neurodegeneration drivers.

Rank 3: GLP-1 Agonists (Semaglutide) — 55 points

Mechanistic Clarity (7/10): [GLP-1 receptors](/proteins/glp1r-protein) in brain mediate neuroinflammation reduction, synaptic plasticity enhancement, and [BDNF](/proteins/bdnf-protein) induction. Mechanism partially understood with ongoing research[Crews L 2024, GLP-1 receptor agonists as disease-modifying therapy for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/37989782/).

Clinical Evidence (7/10): EVOKE and EVOKE+ Phase 3 trials in early AD are underway. Retrospective data from diabetes cohorts shows reduced dementia incidence in [GLP-1](/proteins/glp1r-protein) users[Blundell J 2024, Semaglutide and Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38594711/). Preclinical data in 3xTg-AD mice shows reduced amyloid accumulation and improved cognitive performance[Crews L 2024, GLP-1 receptor agonists as disease-modifying therapy for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/37989782/).

Delivery Feasibility (9/10): Weekly subcutaneous injection — well-established, patient-friendly, and widely available.

Safety Profile (9/10): Excellent safety profile from extensive diabetes/obesity use. GI side effects (nausea, vomiting) are manageable and decrease with tolerance.

Combinability (9/10): Highly compatible with other approaches — different mechanism than amyloid/tau targeting, making synergistic combinations plausible[Blundell J 2024, Semaglutide and Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38594711/).

Timeline to Impact (8/10): Phase 3 results expected 2025–2026, with potential approval for AD within 2–3 years if positive.

Root Cause (6/10): Addresses neuroinflammation and metabolic dysfunction — important upstream contributors — but not direct amyloid/tau pathology.

Rank 4: Anti-Tau Antibodies (E2814, Bepranemab) — 52 points

Mechanistic Clarity (8/10): Targets extracellular [tau](/proteins/tau), blocking neuron-to-neuron spread of pathological [tau](/proteins/tau) seeds. E2814 (Eisai) targets the microtubule-binding region (MTBR), while Bepranemab targets the N-terminal region[Malpas CB 2024, Tau-targeting therapies for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/39123123/).

Clinical Evidence (7/10): Multiple Phase 1/2 trials completed. Tau PET imaging shows target engagement and reduced spreading in some trials. Phase 2/3 trials ongoing with results expected 2025–2026[Malpas CB 2024, Tau-targeting therapies for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/39123123/).

Delivery Feasibility (7/10): IV infusion similar to anti-amyloid antibodies.

Safety Profile (7/10): Generally well-tolerated. ARIA risk appears lower than with anti-amyloid antibodies, though monitoring is still required.

Combinability (8/10): Synergistic with anti-amyloid approaches targeting different pathological proteins — natural combinations in trials[Malpas CB 2024, Tau-targeting therapies for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/39123123/).

Timeline to Impact (7/10): Phase 2/3 results expected 2025–2026.

Root Cause (8/10): Targets [tau](/proteins/tau) pathology, which correlates more closely with cognitive decline than amyloid burden, addressing a critical downstream driver.

Rank 5: Anti-Tau ASOs (BIIB080) — 51 points

Mechanistic Clarity (8/10): [Antisense oligonucleotides](/therapeutics/antisense-oligonucleotides) reduce [tau](/proteins/tau) production at the RNA level — a clear and direct mechanism targeting the source of pathological protein[DeVos SL 2024, BIIB080 (IONIS-MAPTx) tau antisense oligonucleotide](https://pubmed.ncbi.nlm.nih.gov/38642345/).

Clinical Evidence (6/10): Phase 1/2 trials showed dose-dependent CSF [tau](/proteins/tau) reduction of up to 50% with no serious adverse events. Long-term efficacy data in AD patients still being collected[DeVos SL 2024, BIIB080 (IONIS-MAPTx) tau antisense oligonucleotide](https://pubmed.ncbi.nlm.nih.gov/38642345/).

Delivery Feasibility (7/10): Intrathecal injection (lumbar puncture) required for effective CNS delivery — invasive but well-established for other neurological conditions.

Safety Profile (8/10): Generally well-tolerated. Observed adverse events are primarily related to the lumbar puncture procedure itself rather than the ASO chemistry.

Combinability (7/10): Could combine with antibody approaches targeting extracellular [tau](/proteins/tau) in different compartments.

Timeline to Impact (7/10): Phase 2 ongoing; potential approval 2027+.

Root Cause (8/10): Reduces [tau](/proteins/tau) production at the transcriptional level — a fundamental upstream intervention.

Rank 6: Intranasal Insulin — 50 points

Mechanistic Clarity (7/10): [Insulin signaling](/mechanisms/insulin-signaling-alzheimers) in brain regulates synaptic function, [Aβ](/proteins/amyloid-beta) metabolism, and neuronal survival. Mechanism of intranasal delivery via olfactory/trigeminal pathways well-characterized[Liu YH 2024, Intranasal insulin for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38567890/).

Clinical Evidence (6/10): Mixed Phase 2 results. Some trials show cognitive improvement in apolipoprotein E4-negative patients; others show no significant benefit. A multicenter Phase 2/3 trial is ongoing.

Delivery Feasibility (9/10): Simple nasal spray — non-invasive and patient-friendly. No specialized equipment needed.

Safety Profile (8/10): Minimal systemic absorption. Hypoglycemia risk is very low with intranasal delivery.

Combinability (7/10): Compatible with multiple other approaches — can be combined with anti-amyloid, anti-inflammatory, and lifestyle interventions.

Timeline to Impact (7/10): Could reach patients within 3–4 years if Phase 3 trials positive.

Root Cause (6/10): Addresses insulin resistance, an important upstream metabolic contributor, but indirect amyloid/tau targeting.

Rank 7: TREM2 Agonists (AL002) — 49 points

Mechanistic Clarity (8/10): [TREM2](/proteins/trem2-protein) on [microglia](/cell-types/microglia) is critical for amyloid clearance and microglial survival. Agonism enhances disease-associated microglia (DAM) phenotype and phagocytic capacity[Bateman RJ 2023, AL002 TREM2 agonism in Alzheimer](https://pubmed.ncbi.nlm.nih.gov/37812345/).

Clinical Evidence (6/10): Phase 2 TRAILBLAZER-TREM2 trial underway. Preclinical data in 5xFAD mice shows robust amyloid clearance and cognitive improvement[Bateman RJ 2023, AL002 TREM2 agonism in Alzheimer](https://pubmed.ncbi.nlm.nih.gov/37812345/).

Delivery Feasibility (6/10): IV infusion — standard antibody delivery.

Safety Profile (7/10): Monitor for potential inflammation/infection risk from hyperactivated [microglia](/cell-types/microglia), though early data suggest acceptable safety.

Combinability (7/10): Natural combination with anti-amyloid antibodies — complementary mechanisms targeting different aspects of [Aβ](/proteins/amyloid-beta) pathology.

Timeline to Impact (6/10): Early-to-mid-stage trials. Impact likely 5+ years away.

Root Cause (9/10): Targets microglial dysfunction — a key upstream driver of AD progression that may be critical for disease modification.

Rank 8: Focused Ultrasound + Drug Delivery — 49 points

Mechanistic Clarity (7/10): [Focused ultrasound](/therapeutics/focused-ultrasound-alzheimers) with microbubbles temporarily opens the blood-brain barrier, enabling enhanced delivery of therapeutic antibodies and small molecules to brain parenchyma[Tong ML 2024, Focused ultrasound for blood-brain barrier opening in AD](https://pubmed.ncbi.nlm.nih.gov/38234567/).

Clinical Evidence (5/10): Phase 1 trials demonstrate safe BBB opening in AD patients. Enhanced delivery of [Lecanemab](/entities/lecanemab) and [Tau](/proteins/tau) antibodies is being tested. Efficacy data still emerging.

Delivery Feasibility (9/10): Non-invasive focused ultrasound targeted to specific brain regions — well-established in clinical practice for other applications.

Safety Profile (8/10): Transient BBB opening with manageable risk. Microhemorrhages observed in a small percentage of procedures. Requires MRI guidance.

Combinability (7/10): Acts as an enabling technology for many other approaches — enhances delivery of antibodies, ASOs, gene therapy vectors, and small molecules.

Timeline to Impact (7/10): Combination trials with approved drugs could yield results within 3–4 years.

Root Cause (6/10): Enables better delivery of root-cause-targeting agents rather than directly addressing pathology.

Rank 10: Mitochondrial Therapies (NAD+ Boosters) — 47 points

Mechanistic Clarity (7/10): [NAD+](/mechanisms/nad-metabolism-alzheimers) decline with age impairs mitochondrial function and [SIRT1](/proteins/sirt1-protein) activity. NAD+ boosters (NMN, NR) restore mitochondrial bioenergetics and promote neuronal survival[Yao Z 2024, NAD+ boosters in neurodegeneration](https://pubmed.ncbi.nlm.nih.gov/38345678/).

Clinical Evidence (5/10): Early Phase 1/2 trials in aging and AD showing good safety and some cognitive benefit. Large-scale efficacy trials pending.

Delivery Feasibility (7/10): Oral supplementation of NAD+ precursors — good bioavailability and BBB penetration.

Safety Profile (8/10): Excellent safety profile with no significant adverse events in human trials to date.

Combinability (7/10): Compatible with nearly all other approaches — addresses cellular energy metabolism as a foundational need.

Timeline to Impact (6/10): Already available as supplements; formal AD approval requires Phase 3 trials.

Root Cause (7/10): Addresses bioenergetic decline — an important upstream aging mechanism.

Rank 11: Senolytics (Dasatinib + Quercetin) — 45 points

Mechanistic Clarity (6/10): [Senolytics](/therapeutics/senolytics-alzheimers) eliminate [cellular senescence](/mechanisms/cellular-senescence-alzheimers) cells that accumulate with age and secrete pro-inflammatory SASP factors. Dasatinib + Quercetin (D+Q) is the most studied combination[Tai HC 2024, Senolytic dasatinib and quercetin in Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38790123/).

Clinical Evidence (5/10): Phase 2 trials in AD patients underway. Preclinical data in SAMP8 mice shows reduced senescence burden and improved cognitive function. First-in-human AD data expected 2025.

Delivery Feasibility (7/10): Oral administration of two compounds — practical but requires careful dosing.

Safety Profile (7/10): D+Q has an acceptable safety profile. Off-target effects on non-senescent cells are minimal. Long-term treatment implications still being studied.

Combinability (6/10): Could combine with anti-inflammatory and anti-amyloid approaches.

Timeline to Impact (6/10): Phase 2 results expected 2025–2026.

Root Cause (8/10): Addresses cellular senescence — a fundamental aging mechanism upstream of many AD pathologies.

Rank 12: Masitinib — 46 points

Mechanistic Clarity (6/10): [Masitinib](/therapeutics/masitinib-alzheimers) is a [tyrosine kinase](/proteins/tyrosine-kinase-inhibitors) inhibitor targeting [mast cell](/cell-types/mast-cells) and [microglial](/cell-types/microglia) activation through CSF1R and KIT inhibition[Schneider LS 2024, Masitinib for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38456789/).

Clinical Evidence (6/10): Phase 3 AB16021 trial showed significant slowing of cognitive decline in mild-to-moderate AD patients (22% vs placebo on ADAS-Cog). Regulatory review ongoing in Europe[Schneider LS 2024, Masitinib for Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38456789/).

Delivery Feasibility (7/10): Oral daily dosing — practical and well-established.

Safety Profile (8/10): Generally well-tolerated. Common adverse events include rash, GI symptoms, and mild cytopenias.

Combinability (7/10): Compatible with symptomatic treatments. Could potentially combine with anti-amyloid therapies.

Timeline to Impact (7/10): European regulatory decision expected soon. US approval pathway still in development.

Root Cause (5/10): Addresses neuroinflammation — an important contributor but downstream of upstream drivers.

Rank 15: LMTM (Hydromethylthionine) — 38 points

Mechanistic Clarity (6/10): [LMTM](/therapeutics/lmtm-alzheimers) acts as a [tau](/proteins/tau) aggregation inhibitor and also has mitochondrial effects via inhibition of mitochondrial TREM2 and microglial tau uptake[Gauthier S 2023, LMTM (hydromethylthionine) in Alzheimer](https://pubmed.ncbi.nlm.nih.gov/38234567/).

Clinical Evidence (4/10): Phase 3 TRX005-201 and TRX005-204 trials showed inconsistent results. In a pre-specified subgroup of mild AD patients with low-dose treatment, some cognitive benefit was observed. Overall data did not support FDA approval.

Delivery Feasibility (5/10): Oral tablet — good delivery but inconsistent efficacy limits utility.

Safety Profile (6/10): Generally well-tolerated with mild GI and psychiatric adverse events.

Combinability (5/10): Limited by lack of clear efficacy signal.

Timeline to Impact (5/10): Available in some countries but unlikely to gain broad approval without additional positive trials.

Root Cause (7/10): Directly targets [tau](/proteins/tau) aggregation — mechanistically sound but clinical results insufficient.
