Transcutaneous electrical acupoint stimulation for the treatment of withdrawal syndrome in heroin addicts.

Objective: To assess the therapeutic effect of transcutaneous electric acupoint stimulation (TEAS) for the treatment of withdrawal syndrome in heroin addicts.

Methods: A total of 63 male heroin addicts with withdrawal score higher than 20 were recruited in the Detoxification Center of Zhongshan city, Guangdong province, China. They were randomly distributed into two groups: TEAS group (n = 31) received TEAS by using a Han's acupoint nerve stimulator (HANS) model 200A with two output channels, 2-3 sessions per day, 30 minutes per session for 10 consecutive days.

ZNF804A variants confer risk for heroin addiction and affect decision making and gray matter volume in heroin abusers.

Drug addiction shares common neurobiological pathways and risk genes with other psychiatric diseases, including psychosis. One of the commonly identified risk genes associated with broad psychosis has been ZNF804A. We sought to test whether psychosis risk variants in ZNF804A increase the risk of heroin addiction by modulating neurocognitive performance and gray matter volume (GMV) in heroin addiction.
