Cocaine addiction may affect how the body processes iron, leading to a build-up of the mineral in the brain, according to new research from the University of Cambridge. The study, published today in Translational Psychiatry, raises hopes that there may be a biomarker – a biological measure of addiction – that could be used as a target for future treatments.
People who are addicted to cocaine are particularly prone to developing habits that render their behaviour resistant to change, regardless of the potentially devastating consequences, suggests new research from the University of Cambridge. The findings may have important implications for the treatment of cocaine addiction as they help explain why such individuals take drugs even when they are aware of the negative consequences, and why they find their behaviour so difficult to change.
The discovery of a brain circuit ‘shortcut’ could explain why some addicts unintentionally relapse, and suggests that a shift in focus for therapies might help those who want to stay off drugs.
Individuals addicted to cocaine may have difficulty in controlling their addiction because of a previously-unknown ‘back door’ into the brain, circumventing their self-control, suggests a new study led by the University of Cambridge.
Medicines which increase levels of the brain chemical dopamine may hold the key to helping those addicted to cocaine and amphetamines kick the habit, researchers from the University of Cambridge have found.
