In the first long-term follow-up of patients treated with buprenorphine/naloxone for addiction to opioid pain relievers, half reported that they were abstinent from the drugs 18 months after starting the therapy.
Young adults who had been maltreated as children differed from others who had not been maltreated in the connectivity of nine cortical regions. The differences could compromise the maltreated group’s basic social perceptual skills, ability to maintain a healthy balance between introversion and extroversion, and ability to self-regulate their emotions and behavior.
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.
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.
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.
