On the cause of Alzheimer’s disease

Research papers, references, and analysis by Richelle Gayle Cutler, Ph.D.

This site presents a body of work submitted as an entry for the Oskar Fischer Prize — an international challenge, funded through the University of Texas at San Antonio, to synthesize the literature and put forward a comprehensive explanation for the cause of Alzheimer’s disease. The central paper argues that occult herpesvirus infection is a non-genetic driver of the disease. The entry, its references, and an independent evaluation of the work are gathered here and made openly available as a public disclosure for scientific review.

01

The working hypothesis

Occult herpesvirus infection as a non-genetic driver of Alzheimer’s — set within a multifactorial model of the disease.

Dr. Cutler’s central proposal is that the common, lifelong herpesviruses most adults carry — usually silently are a major non-genetic driver of sporadic Alzheimer’s disease. Rather than one pathogen acting alone, several human herpesviruses (HSV-1 and -2, VZV, HCMV, HHV-6A/B, HHV-7, and EBV) converge beginning with alphaherpesvirus infection of neurons in the locus coeruleus. From there, infected locus coeruleus neuron axons projecting throughout the brain can selectly send infectious particles, non-infectious particles and viral exosomes to brain regions highly innervated by locus coeruleus processes that use kinesin for transporting vesicles. One regions that is particular susceptible is laminar I of the cerebral cortex. Laminar I is filled with interneurons that release GABA and modulate apical tuft dendrites of pyramidal neurons whose cell bodies reside in Layers II, III, and V. Latently infected neurons and other infected cell types can still secrete viral exosomes with viral proteins that cause neurodegeneration, e.g., VP22.

Thus, a distinctive feature of the model is that significant damage is carried by non-infectious secreted factors, so a small number of infected cells can injure many neighbours — “non-cell-autonomous” neurodegeneration. That helps explain a long-standing puzzle: why viral DNA is so hard to detect in end-stage Alzheimer’s brain tissue even if a virus set the disease in motion decades earlier.

The infectious idea is not new. Oskar Fischer and Alois Alzheimer both suspected, in 1907, that microbes might help form the plaques they described, and modern work has revived the theory — showing that herpesviruses can trigger the amyloid, tau, and neuroinflammatory hallmarks of the disease, and that amyloid-β itself can act as an antimicrobial peptide whose protective response turns harmful when infection becomes chronic.

Crucially, this is not a single-cause theory. Alzheimer’s is understood as a complex, multifactorial disease, in which the herpesvirus burden a person carries — their viral load and how often it reactivates — together with their genetics, age, and environmental and lifestyle factors such as diet and a sedentary lifestyle, determine both the age of onset and the rate of disease progression.

These factors interact rather than simply add up:

  • Viral load & reactivation — which herpesviruses a person carries, how much, and how often they reactivate to secrete damaging factors.
  • Genetics — risk alleles such as APOEε4: carriers who have recently reactivated HSV-1 have been reported to develop Alzheimer’s at roughly three times the rate of those who merely carry the virus, while non-carriers show no such effect — a clear gene-by-environment interaction.
  • Age — the single largest risk factor; with time, herpesviruses reactivate more readily and immune surveillance wanes.
  • Environment & lifestyle — stress, diet, physical activity, and other exposures that shape how often the virus reactivates and how well the brain withstands it.

This systems-level view fits Dr. Cutler’s own scientific training. Her doctoral research, in the neurogenetics laboratory of Dr. Robert W. Williams, mapped how genetic and environmental factors interact to shape a complex biological trait, and her postdoctoral work characterised non-cell-autonomous degeneration — the very mechanism the hypothesis places at the centre of Alzheimer’s pathology.

The researcher

A neurobiologist and registered patent agent whose work spans the bench and the patent office.

Richelle Gayle Cutler holds a Ph.D. in Neurobiology from the University of Tennessee Health Science Center and a B.S. in Biochemistry and Molecular Biology from the University of Maryland, Baltimore County. She trained in the Department of Anatomy and Neurobiology, in the neurogenetics laboratory of Dr. Robert W. Williams, where quantitative-trait-locus (QTL) mapping let her dissect how genetic and environmental factors together shape complex traits — quantifying their control over neuron number and brain size across mouse strains. The work grounded her in both complex-trait genetics and detailed neuroanatomy — mapping and counting neuronal populations across the brain and retina — and she taught medical students both gross anatomy and neuroanatomy. That gene-by-environment, whole-system training is the same thinking that runs through her multifactorial view of Alzheimer’s disease.

Her engagement with the disease is long-standing. Among her earliest peer-reviewed work is a study of altered muscarinic (cholinergic) signal transduction in aging and Alzheimer’s brain (Brain Research, 1994). She went on to study neurodegeneration directly: as a post-doctoral fellow at the Johns Hopkins Wilmer Eye Institute she led the development and characterization of a tetracycline-inducible transgenic mouse model of retinitis pigmentosa, examining the mechanism of non-cell-autonomous cone-cell degeneration — the same non-cell-autonomous principle that anchors the herpesvirus theory presented here.

At the Fred Hutchinson Cancer Research Center she developed a competitive binding assay to optimize the targeting of pH-responsive micelles carrying siRNA to lymphoma cells, and ran siRNA-mediated gene-knockdown experiments using RT-qPCR and high-throughput fluorometric enzyme assays. That combination of molecular neuroscience and therapeutic delivery underlies the technical range she later brought to patent practice.

Registered before the U.S. Patent and Trademark Office in 2015, she has more than six years drafting and prosecuting U.S. and international patent applications across the life sciences — virology, immunology, recombinant fusion proteins, genomics, antibodies, CRISPR gene editing, RNA interference, recombinant bacteria, and small-molecule drugs — including work supporting academic inventors and university technology transfer. She is the sole inventor on U.S. Patent No. 12,428,643, directed to RNA interference in therapeutic compositions and methods of treatment. A continuation of that patent is pending, published as U.S. 2026/0098267 A1, and a further application, published as PCT WO 2025/097185 A1, is pending in the U.S. national phase.

Oskar Fischer Prize entry

Herpesviruses as a non-genetic driver of Alzheimer’s disease — the full paper, transcribed for open reading with all figures.

Executive summary

Occult herpesvirus infections could be the non-genetic driver of sporadic Alzheimer’s disease. Neurotropic alphaherpesviruses can infect adrenergic neurons of the locus coeruleus, where secreted viral factors — such as herpesvirus glycoprotein B — disrupt endosomal trafficking, displace amyloid precursor protein (APP) from the cell surface, and drive amyloidogenesis and tau hyperphosphorylation.

Loss of APP destabilizes inhibitory α2-adrenergic autofeedback, producing persistent norepinephrine release and a cascade that links immunosuppression, insulin deficiency, vascular inflammation, and hypoxia. Because the damage is carried by secreted factors, a small number of infected cells can produce the diffuse degeneration seen in Alzheimer’s — explaining why viral DNA is so hard to detect. The paper argues that multiple herpesvirus types act together in disease pathogenesis.

AI analysis of the entry

An independent, AI-generated critical evaluation of the entry — scored against the Oskar Fischer Prize criteria.

The evaluation

A doctoral-thesis-style review assesses the herpesvirus theory against the Convergent Autophagic Collapse model of Alzheimer’s — a six-stage account of lysosomal failure. It maps the entry’s viral mechanisms (pp150–Rab6 displacement, UL56/APP mimicry, gB-seeded amyloidosis) onto that pathway and proposes a unified “viral-secretory-lytic” synthesis, before scoring the work against the prize criteria.
