This hypothesis proposes that mitochondrial dysfunction represents a primary pathogenic mechanism in Alzheimer's disease, operating through impaired ATP synthesis and increased oxidative stress that precedes and drives amyloid-beta accumulation. Specifically, mutations or age-related damage to TFAM (Transcription Factor A, Mitochondrial) lead to defective mitochondrial DNA replication and reduced expression of respiratory chain complexes I and IV. This mitochondrial impairment creates a bioenerg
## Mechanistic Overview
TFAM overexpression creates mitochondrial donor-recipient gradients for directed organelle trafficking starts from the claim that modulating TFAM within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The transcription factor A, mitochondrial (TFAM) serves as the master regulator of mitochondrial DNA (mtDNA) transcription and copy number maintenance, making it a cri
