Gap 006 analysis (archived stub)
Analysis for knowledge gap 006 in the neurodegeneration domain.
These hypotheses emerged from the same multi-agent debate that produced this hypothesis.
VPS41 and HOPS complex dysfunction impairs autophagosome-lysosome fusion, causing accumulation of α-synuclein oligomers and increased exosome release. Mechanistically plausible but causality direction remains ambiguous. Tier 3 feasibility.

Mechanism: TDP-43 proteinopathy leads to progressive nuclear depletion of functional TDP-43, causing widespread alternative splicing defects at synapses, part
Temporal Causality Assumption
The hypothesis assumes nuclear TDP-43 depletion drives splicing dysfunction rather than being a consequence of earlier upstream insults. This assumes causation from correlation—a foundational logical flaw. Nuclear depletion may be a compensatory response, an epiphenomenon, or a parallel process occurring alongside (not before) other pathogenic events.
