Amyotrophic Lateral Sclerosis

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

Amyotrophic lateral sclerosis (ALS) is represented in SciDEX as a motor-neuron vulnerability syndrome where RNA-binding protein pathology, proteostasis failure, mitochondrial stress, glial inflammation, and axonal degeneration converge. The comparison infographic above links ALS to PD and AD through mechanisms that recur across neurodegeneration while preserving the motor-neuron-specific biology that distinguishes ALS.

ALS-specific SciDEX hypotheses emphasize TDP-43 nuclear depletion and cytoplasmic aggregation, SOD1 proteotoxic stress, STMN2 splicing loss, TBK1-linked microglial senescence, motor-neuron axon degeneration, and selective vulnerability created by disrupted autophagy and mitophagy. These mechanisms connect directly to the shared disease axes of protein aggregation, mitochondrial dysfunction, lysosomal-autophagy failure, and neuroinflammation.

This page uses the infographic as a compact orientation layer for readers moving between ALS hypotheses, wiki pages, debates, and future Forge validation tasks.
