DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Brain cells may age faster in people with cocaine use disorder

A new study finds evidence from the DNA methylome that the biological age – different from the chronological age – of cells in Brodmann Area 9 of the prefrontal cortex might be greater in people with cocaine use disorder.

Cocaine use disorder leads to changes in the 'methylome' of a brain region

Scientists tend to view substance addiction as primarily a disease of the brain. When we enjoy sex, food, music, or hobbies, regions of our brain within the reward pathway are flooded with pleasure-inducing dopamine.
