Addiction cravings due to lack of a protein

Mice that do not have a protein called PSD-95 tend to be more addicted to drugs such as cocaine, say researchers at Edinburgh University, Scotland.


Researchers say that their experiments could lead to drugs that would help drug addicts and people with learning difficulties.


The scientists said that their experiments on mice led them to conclude that the protein PSD-95, when there is not enough of it in the body, is responsible for addiction and learning difficulties.


It is common for drug addicts to have memory problems and coordination difficulties.

The researchers in Wales say that this is because they suffer from molecular brain damage.


Their research could lead to drugs that reverse the damage.
