| High metabolic demand | Neurons have high oxidative phosphorylation, producing reactive oxygen species (ROS) that cause oxidative DNA damage |
| Non-dividing state | Unlike other cell types, neurons cannot use cell division to dilute accumulated DNA damage |
| Long lifespan | Human neurons must maintain genome integrity for decades |
| Associated Diseases | Alzheimer's disease, Parkinson's disease |
