Effect of electro-acupuncture intervention on cognition attention bias in heroin addiction abstinence—A dot-probe-based event-related potential study
摘要
To study the changes of cognitive attention-related brain function in the heroin addicts before and after electro-acupuncture (EA) intervention for exploring the concerned neuro-mechanism of addictive relapse and the central action role of EA intervention. Adopting event-related potential (ERP) technique
the ERP at 64 electrode spots in 10 heroin addicts (test group) were recorded before and after EA intervention with dot-probe experimental form during implementing cognitive task on positive emotional clue (PEC)
negative emotional clues (NEC)
and heroin-related clue (HRC). The P200 amplitude components on the selected observation points (Fz
Cz
and Pz) were analyzed and compared with those obtained from 10 healthy subjects as the control. Before EA
the ERP of attention on HRC in the test group was higher than that on PEC and NEC (P<0.05) and significantly higher than that in the control group (P<0.05); after EA
the P200 amplitude of attention on HRC at Cz and Pz was significantly lowered (P<0.05) and that on PEC at Fz was significantly elevated (P<0.05). After EA
the P200 amplitude at Pz was ranked as NEC > PEC > HRC
but in the control group
it showed PEC > HRC at all three observation points and PEC > NEC at Pz. Heroin addicts show attention bias to HRC
which could be significantly reduced by EA intervention
illustrating that EA could effectively inhibit the attention bias to heroin and so might have potential for lowering the relapse rate.
