From Analysis:

Human connectome alterations in Alzheimer's disease: structural and functional network disintegration

How does the human brain connectome reorganize in Alzheimer's disease, and what are the vulnerable hub regions that drive network-wide disintegration? Does connectome breakdown precede or follow amyloid/tau pathology, and can graph-theoretic measures of connectome integrity serve as early biomarkers of neurodegeneration?

Dimension Scores

How to read this chart: Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential. The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength), green shows moderate-weight factors (safety, competition), and yellow shows supporting dimensions (data availability, reproducibility). Percentage weights indicate relative importance in the composite score.

✓ Supporting Evidence 5

Tau propagates along connected networks in an activity-dependent manner

PMID:26928048

EphB2 regulates NMDA receptor trafficking and synaptic function

PMID:15834409

Synaptic activity increases extracellular tau release and uptake

PMID:22371515

Ephrin-B2 involved in activity-dependent synaptic plasticity mechanisms

PMID:15596161

Hub regions serve as propagation nodes for transneuronal pathology spread

PMID:28716878

✗ Opposing Evidence 5

Direct evidence linking EphB2 to tau propagation is limited - circumstantial only

PMID:15834409

HSPGs and LRP1 are more strongly implicated in tau uptake than ephrin receptors

PMID:30146301

No selective EphB2 agonists or antagonists in clinical development - only research tools

PMID:15834409

Tau immunotherapy trials (ABBV-8E12, semorinemab) failed - tau removal may not be sufficient

PMID:26928048

EphB2 changes in AD may be downstream consequence of synaptic loss, not driver

Novel Therapeutic Hypotheses: Connectome Preservation in Alzheimer's Disease

Hypothesis 1: Network-Directed Anti-Amyloid Immunotherapy via Transcranial Focused Ultrasound

Description: Transcranial focused ultrasound (tFUS) can transiently open the blood-brain barrier in AD patients, enabling targeted delivery of anti-amyloid antibodies specifically to hub regions showing highest connectivity burden. This approach exploits the spatial correlation between hub vulnerability and amyloid accumulation to concentrate therapeutic effect where it is most needed.

Target: Blood-brain ba

Critical Evaluation of Connectome Preservation Hypotheses in Alzheimer's Disease

Overview Assessment

These seven hypotheses collectively represent a sophisticated network-level approach to AD therapeutics, moving beyond the amyloid-centric paradigm. However, they share several systemic weaknesses: (1) heavy reliance on correlative rather than causal evidence for hub vulnerability, (2) limited validation in human tissue/clinical data, and (3) insufficient consideration of compensatory mechanisms and stage-dependent effects. I will evaluate each hypothesis individually before providing
