The effect of trancecranial Direct Current Stimulation (tDCS) on reduction of craving, depression and anxiety in students with tramadol abuse: Preliminary study

The aim of the present study is to examine the effectiveness of trancecranial Direct Current Stimulation (tDCS) on reduction of craving, depression and anxiety in students with tramadol abuse.
This research is an experimental single subject (ABA) study. The population of this research is total students of tramadol abuser of Mohaghegh Ardabili University that among them, three students were selected by non-accidental sampling method that were volunteer to participate in this research. For gathering the data, Franken craving quesionnare (2002) and Lewinda depression anxiey scale (1995) were utilized. Treatment sessions of trancecranial Direct Current Stimulation (tDCS) in 10 sessions 20 minutes was performed which anode electrode was placed on left dorsolateral prefrontal cortex (F3) and cathode electrode was placed on right dorsolateral prefrontal cortex (F4) and 2M/A severity of electrical current was traced from scalp. According to being single subject of this research, for analyzing of data, procedural changes, slope, improvement percentage, and effect size level were used for every patient.
The results indicate the effectiveness of this method on reduction of craving, depression of tramadol abusers, therefore it is suggested for addiction therapist and psychotherapist to use trancecranial Direct Current Stimulation (tDCS) as a intervention method in treatment of these patients.
