Abstract: Neurodegenerative disorders are distinguished by the progressive loss of anatomically or physiologically
relevant neural systems. Atypical mitochondrial morphology and metabolic malfunction are found in
many neurodegenerative disorders. Alteration in mitochondrial function can occur as a result of aberrant mitochondrial
DNA, altered nuclear enzymes that interact with mitochondria actively or passively, or due to unexplained
reasons. Mitochondria are intimately linked to the Endoplasmic reticulum (ER), and ER-mitochondrial
communication governs several of the physiological functions and procedures that are disrupted in neurodegenerative
disorders. Numerous researchers have associated these disorders with ER-mitochondrial interaction disturbance.
In addition, aberrant mitochondrial DNA mutation and increased ROS production resulting in ionic
imbalance and leading to functional and structural alterations in the brain as well as cellular damage may have
an essential role in disease progression via mitochondrial malfunction. In this review, we explored the evidence
highlighting the role of mitochondrial alterations in neurodegenerative pathways in most serious ailments,
including Alzheimer’s disease (AD), Parkinson’s disease (PD), and Huntington’s disease (HD).
