July 2015 A can-do attitude, ability to cope with potential triggers for drug use, readiness to change, and participation in self-help programs are major assets for people trying to recover from cocaine addiction.
September 2015 A NIDA-supported study has found that a cocaine-addicted person’s chance of managing 1 whole year of abstinence correlates with activity levels in these impaired motivational and decision-making brain areas.
September 2015 In mice, a cocaine-induced imbalance in the activity of two key populations of neurons in the reward system persists for a longer period after repeated exposure to the drug. For long-term users, this change could both weaken the cocaine “high” and strengthen the compulsion to seek the drug.
Two researchers share their reasons for researching transcranial magnetic stimulation (TMS) for treating cocaine addiction, and describe challenges to moving forward this potentially promising therapy.
January 2016 Giving mice a modified version of a naturally occurring gene blocks cocaine’s stimulant effects without affecting the animals’ physiological or metabolic health. The new evidence advances the proposed therapy a step closer to readiness for testing in people.
February 2016 The protein acid-sensing ion channel 1A (ASIC1A) is naturally present in the brain and reduces laboratory animals' attraction to environments in which they have experienced cocaine's effects.
During investigations into using transcranial brain stimulation (TMS) to treat cocaine abuse, two projects take diverging paths. One researcher moves to the next stage, while another is forced to cut his trial short.
