Drug addiction also carries genetic factors

A recent study in the UK shows that drug addicts have genetic abnormalities in some parts of the brain that make addicts lose their ability to control behavior.

Previous research has shown these differences, but it is unclear how the brain is destroyed by addiction and the reason why it is easier for them to get into addiction than others.

Scientists at Cambridge University compared the brain of an addicted to the brains of non-addicted relatives as well as healthy volunteers who are not related by blood. The results show that relatives of the drug addicts share many similarities with the brains of the "brown fairy's disciples".

This suggests that brain defects are family-based, although relatives of addicts may not fall into the path of addiction through habitat or other brain structures.

Research group Karen Ersche, of the University of Cambridge, said: 'It is not uncommon to argue that common people with addicts must have some self-healing factors that prevent them from being affected calculating the family line in the brain makes them dependent on drugs. The fact that people are addicted to certain drugs may be a way to find a balance between brain defects that are inextricably linked to self-control. "

The scientists also found that cohabiting couples - an addict and a non-addicted person - participated in the study in response to worse investigations than other healthy volunteers. This shows that addiction is actually a family factor and explains why there are families with a lot of addicts while other families do not.
