Multifactorial risk accumulation model

Multifactorial Risk Accumulation Model enters the Adult Cognitive Disease corpus through the work of Leonard Nelson (submission 149), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Leonard Nelson's submission is summarised in this corpus as:

Alzheimer's disease originates from cerebral capillary microbleeds. The author proposes that aging-related autonomic imbalance and orthostatic blood-pressure swings cause intermittent cerebral hypoxia/reoxygenation that injures the capillary blood-brain barrier, producing micro-haemorrhages; amyloid-beta is then generated by astrocytes and platelets as a fibrotic scaffold to repair the breached barrier, so the amyloid plaque is a wound-repair scar rather than a misfolded toxin. Chronic, unsuccessful repair sustains inflammation and glutamate excitotoxicity that drives cytoskeletal disrepair, tau tangles, and neurodegeneration, positioning the microbleed as the missing link that unifies the amyloid-cascade and vascular hypotheses.

Where it sits

The submission scores against the framework's convergence nodes as: ApoE4 hub 5 · compensatory paradigm 4 · transcriptional / epigenetic 3 · cytoskeletal collapse 2 · neuroimmune interface 2.

Its declared subject matter: cerebral-microbleeds, vascular-hypothesis, blood-brain-barrier, amyloid-as-repair, cerebral-amyloid-angiopathy, neurovascular-unit, wnt-gsk3beta, capillary-injury.

Named by the same submission

3 other concepts enter the corpus through the same paper, so they cover adjacent ground: Resilience as key to understanding AD clinical expression · Somatic mutations as novel therapeutic targets · SuperAgers demonstrate pathology-cognition dissociation.

Assembled from the corpus rather than written: the summary is quoted from the submission that named it; the node scores are read from its dossier. It has not yet been expanded into an article.
