Olfactory vector hypothesis

Olfactory Vector Hypothesis enters the Adult Cognitive Disease corpus through the work of Brian Balin (submission 77), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Brian Balin's submission is summarised in this corpus as:

Chlamydia pneumoniae infection in the brain is a causative factor in late-onset sporadic Alzheimer's disease. The bacterium enters the CNS via the olfactory pathway and blood-brain barrier, establishes chronic persistent infection, and triggers neuroinflammation, amyloid deposition, and tau phosphorylation. APOE epsilon-4 allele enhances bacterial attachment to host cells, explaining the genetic-infection interaction in AD risk.

The source paper puts the concept to work directly:

The “olfactory vector hypothesis” suggests that diseases such as AD and Parkinson’s disease (PD) may be caused or triggered by agents entering the brain through the nose, and is not a new concept.

Where it sits

The submission scores against the framework's convergence nodes as: neuroimmune interface 8 · ApoE4 hub 8 · endosomal nexus 3 · cytoskeletal collapse 1 · compensatory paradigm 1 · transcriptional / epigenetic 1.
