The gene variant, CYP2E1 appears to make people more sensitive to alcohol and can generate free radicals. Researchers consider a future application for drugs containing CYP2E1 for both making people more sensitive to alcohol prior to drinking, and to assist in the process of sobering up.
Neuroscientists at the University of Copenhagen have developed a model which demonstrates how the brain releases dopamine. The model could provide a key insight into how the brain perceives punishment and reward. The researchers hope that their newly developed model could assist other scientists to better understand drug addiction and provide new treatments for schizophrenia.
New research suggests heavy alcohol use in teens can detrimentally affect neural development. Researchers have concluded that binge drinking can negatively disrupt normal developmental processes, leading to problems with learning and social adjustment in the long term. The study also discovered that increased use of alcohol can result in a decrease in attention and executive function. Additionally, increased marijuana use was discovered to decrease memory performance.
Researchers at the University of Liverpool have discovered that high levels of cortisol could increase the risk of relapse for recovering alcoholics. Cortisol, a hormone produced in the adrenal gland as a result of stress, is found in elevated levels both in alcoholics and those in recovery.
New research released in the Journal of Neuropsychopharmacology has shown that the drug Disulfiram, commonly used to treat alcoholism, can also help treat cocaine addiction.
