The neurobiology of addiction
Introduction
Neuroscience is started to reveal the neurochemical changes that occur within particular functional regions of the brain that are responsible for the behaviour in addiction, so neuroscience and motivational impairment that require treatment. Our cognitive abilities enables us to quickly identify which activities are worth pursuing in our environment . In addiction , drug use become over –learned because repeated drug use can over activities

Such as relationship, work and education. These changes are also believed to explain why the pursuit of drugs can come to dominate the lives of many addicts, at the expense of most other interest (Adrian Carter, Wayne Hall & Benjamin Capps,2009,p.29)
Addiction also impairs a number of other cognitive process that perpetuate drug use many of these are included in the diagnostic criteria for drug dependence or addiction (WHO, 1993b; APA,2000) They include
• A feeling of compulsion to use drugs
• An impaired ability to avoid using drugs when opportunities arise
• An impaired understanding of the consequence of continued drug taking ;and
• The ability for cues associated with drug use and stress to produce a relapse to drug use in an abstinent individual , even months or year after stopping.
This essay will review the relation of neuroscience with addiction and will explain how the chronic abuse of addictive drug can alter the neurochemical structure and function of the brain in ways that lead to the psychology of addiction.
Neuroscience and

(2009, p.31 ) discuss the idea that neuroscience offer that addiction is a pathological behaviour in which addictive drugs co-opt normal learning and motivating pathways in the brain so that drug taking comes to dominate all other goal directed activities such a view has the potential to not only unlike a wide array of new and powerful treatment of addiction that target or ameliorate these changes. Given the central important of the brain and the strong moral attitude that many people feel towards who abuse or are addicted to drugs , the nature and impact of these changes needs to be considered such an analysis will need to critically examine the emerging neuroscience research on
