🧪 Overview

Motor neurons exhibit unique metabolic dependencies on glycolysis and lipid metabolism that become dysregulated in ALS. Targeting PDH kinase or SGLT2 to shift toward glucose oxidation may restore energy homeostasis. However, causal linkage to ALS progression is weak, and SOD1 metabolic rescue is a poor predictor for sporadic ALS.

⚖️ Evidence

⚖️ Evidence Matrix3 supports3 contradicts
Supports
Motor neurons have reduced PDH activity and prefer glycolysis
PMID:29656893
Supports
SGLT2 expression elevated in ALS motor neurons; inhibition extends survival in SOD1 mice
PMID:34193629
Supports
PGC-1α dysregulation observed in ALS patients and models
PMID:18391957
Contradicts
SOD1-G93A mice show high variability in metabolic phenotypes
PMID:unreported
Contradicts
SGLT2 inhibitors in humans did not show cognitive benefits
PMID:unreported
Contradicts
PDK/glycolysis shift may be compensatory, not causative
PMID:unreported
