<p>Alzheimer's disease (AD) is a neurodegenerative disorder that causes progressive neurodegeneration and a variety of cognitive deficits. Of note, mitochondrial malfunctions occur early in the disease's development. Mitophagy impairment leads to the build-up of damaged mitochondria inside the cells, causing malfunction and eventual death of the cells. This review summarizes the mechanisms linking mitochondrial damage and autophagy dysregulation to AD and highlights potential therapeutic opportunities. We summarize how mitochondrial dysfunction contributes to AD, including defects in mitochondrial biogenesis, impaired dynamics, the impact of AD-related protein aggregates on mitochondrial integrity, and defective axonal transport. We also explore the roles of mitophagy in AD, including its function in the removal of harmed proteins and organelles. Finally, we highlight the therapeutic strategies for the treatment of AD, targeting molecular components involved in mitochondrial damage and autophagy dysregulation in AD, i.e., antioxidants, mitochondrial modulators, and mitophagy enhancers.</p>
