Mitochondrial aging plays a central role in the functional decline of the central nervous system (CNS), with profound consequences for neurological health. As the brain is one of the most energy-demanding organs, neurons are particularly susceptible to mitochondrial dysfunction that arises with aging. Key features of mitochondrial aging include impaired mitochondrial dynamics, reduced mitophagy, increased production of reactive oxygen species (ROS), and accumulation of mitochondrial DNA (mtDNA) mutations. These alterations dramatically compromise neuronal bioenergetics, disrupt synaptic integrity, and promote oxidative stress and neuroinflammation, paving the path for the development of neurodegenerative diseases. This review also examines the complex mechanisms driving mitochondrial aging in the central nervous system (CNS), including the disruption of mitochondrial-organelle communication, and explores how mitochondrial dysfunction contributes to neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis. By synthesizing current evidence and identifying key knowledge gaps, we emphasize the urgent need for targeted strategies to restore mitochondrial function, maintain cognitive health, and delay or prevent age-related neurodegeneration.
