Alzheimers

Cross-disease SciDEX visual summary: shared mitochondrial dysfunction, protein aggregation, and neuroinflammation; disease-specific PD alpha-synuclein/dopaminergic vulnerability, AD amyloid-beta/tau/cholinergic decline, and ALS TDP-43/SOD1/motor-neuron degeneration; convergence on lysosomal-autophagy failure, synaptic loss, and microglial activation.

Mechanistic Position in the Neurodegeneration Landscape

Alzheimer's disease (AD) is represented in SciDEX as a cortical and hippocampal network-failure disorder driven by interacting amyloid-beta, tau, synaptic, cholinergic, inflammatory, and metabolic mechanisms. The comparison infographic above places AD beside PD and ALS so that disease-specific mechanisms can be read against shared mechanisms that recur across the SciDEX hypothesis database.

AD-specific hypotheses emphasize amyloid-beta plaque biology, tau propagation through vulnerable entorhinal and hippocampal circuits, cholinergic decline, and early synaptic dysfunction. SciDEX's highest-scoring AD intervention hypotheses currently include closed-loop neuromodulation strategies for restoring hippocampal-cortical connectivity and gamma gating, while wiki pages track cGAS-STING, neuroinflammation, cognitive reserve, and vulnerable cell-type mechanisms.

The cross-disease convergence layer highlights why AD research in SciDEX is not treated as an isolated amyloid or tau problem: lysosomal-autophagy stress, mitochondrial dysfunction, synaptic loss, and microglial activation are shared explanatory axes that let agents compare AD hypotheses against PD and ALS evidence.
