Brains of addicts are inherently abnormal: study
It is interesting how the scientists doing the research see only two possibilities in explaining behavior: social environment or genetic predisposition; what ever happened to "moral choice"?
Or maybe there is only a predisposition to addiction and their behavvior cemented this predisposition by altering their brain even further by their behavior?
It has been shown that behavior affects brain development and shanges it even in adulthood over years of repeated behavior.
I feel very skeptical that the brain DETERMINES our behvaior, but only can stack the deck some so that we are more likely to follow in that direction.
But all of us always have a choice with each thing we do.
Drug addicts have inherited abnormalities in some parts of the brain which interfere with impulse control, said a British study published in the United States on Thursday.
Previous research has pointed to these differences, but it was unclear if they resulted from the ravages of addiction or if they were there beforehand to predispose a person to drug abuse.
Scientists at the University of Cambridge compared the brains of addicts to their non-addicted siblings as well as to healthy, unrelated volunteers and found that the siblings shared many of the same weaknesses in their brains.
That indicates that the brain vulnerabilities had a family origin, though somehow the siblings of addicts -- either due to environmental factors or other differences in brain structure -- were able to resist addiction.
"Presumably, the siblings must have some other resilience factors that counteract the familial vulnerability to drug dependence," said the study led by Karen Ersche of the University of Cambridge, published in the journal Science.
"An individual's predisposition to become addicted to stimulant drugs may be mediated by brain abnormalities linked to impaired self-control."
