Part I. Focuses on the effects of drug addiction on the brain. How addictive drugs affect the nucleus accumbens (NAC); Effects of drugs on dopamine and motivation; Capacity of drugs to disturb the different processes in the brain.EBSCO_AspHarvard Mental Health Letter...
Because substances of abuse act directly on the reward center of the brain to deliver their high—this involves speedy and intense release of the neurotransmitter dopamine—addiction can be seen as a shortcut to reward, one that, over time, can have a high cost to physical and mental health....
But did you realize that your brain has a direct effect on addiction? The Genetics of Addiction Studies have been completed that expose identical twins to the same stimulus but don’t always result in addiction. In fact, approximately 50% of the time an addiction occurs, suggesting a genetic...
Alcohol addiction: A disorder of self-regulation but not a disease of the brain However, it is the wider perspective on addiction, and not the more local one on alcohol addiction per se, that I am primarily interested in here. I do not claim to present anything like a theory of addiction...
Based on brain imaging findings, we present a model according to which addiction emerges as an imbalance in the information processing and integration among various brain circuits and functions. The dysfunctions reflect (a) decreased sensitivity of reward circuits, (b) enhanced sensitivity of memory ...
I combine neuroscience with genetics to understand how alcohol and drugs influence the brain. In the past decade, I have seen changes in our understanding of the molecular mechanisms of addiction, largely due to a better understanding of how genes are dynamically regulated in the brain. New ways...
Advances in neuroscience identified addiction as a chronic brain disease with strong genetic, neurodevelopmental, and sociocultural components. We here discuss the circuit- and cell-level mechanisms of this condition and its co-option of pathways regulating reward, self-control, and affect. Drugs of ...
Addiction and the Teenage Brain Learning Target: I can explain how addictive substances work in the brain, creating tolerance, dependence and addiction. Do Now: Write one question about addictive substances (tobacco, alcohol, illegal drugs and prescription drug abuse) on the board. We’ll come ba...
To deepen understanding of efforts to consider addiction a brain disease, we review critical appraisals of the disease model in conjunction with responses from in-depth semistructured stakeholder interviews with (1) patients in treatment for addiction and (2) addiction scientists. Sixty-three patients...
