Study suggests nicotine addiction might be controlled by influencing brain mechanisms
There is a clear link between GABA - a chemical substance of the central nervous system that inhibits neurons in the brain - and nicotine dependence, according to a study presented today at the American College of Neuropsychopharmacology (ACNP) annual meeting. view more (2007-12-10)
Mental illness and drug addiction may co-occur due to disturbance in part of the brain
Why do mental illness and drug addiction so often go together" New research reveals that this type of dual diagnosis may stem from a common cause: developmental changes in the amygdala, a walnut-shaped part of the brain linked to fear, anxiety and other emotions. view more (2007-12-03)
